Tamoxifen Citrate
Indications
Breast cancer
Indication detailsView
Tamoxifen is indicated for the treatment of breast cancer.
Therapeutic classView
Hormonal Chemotherapy
PharmacologyView
Tamoxifen is a praparation of Tamoxifen which is a non-steroidal, triphenylene based drug and displays a complex spectrum of oestrogen antagonist and oestrogen agonist like pharmacological effects in different tissues. In breast cancer patients, at the tumour level, Tamoxifen acts primarily as an antioestrogen, preventing oestrogen binding to the oestrogen receptor. Additionally Tamoxifen has been reported to lead to maintenance of bone mineral density in post-menopausal women.
DosageView
Adults (including elderly): The dosage range is 20 to 40 mg daily, given either in divided doses twice daily or as a single dose once daily.
Side effectsView
Side effects can be classified as either due to the pharmacological action of the drug, e.g., hot flushes, vaginal bleeding, vaginal discharge, pruritus vulvae and tumour flare or as more general side effects, e.g., gastrointestinal intolerance, headache, light-headedness and occasionally fluid retention and alopecia. When such side effects are severe, it may be possible to control them by a simple reduction of dosage (within the recommended dose range) without loss of control of the disease.
Skin rashes including isolated reports of erythema multiforme, Stevens Johnson syndrome and bullous pemphigoid and rare hypersensitivity reactions, including angio-oedema have been reported. A small number of patients with bony metastases have developed hypercalcaemia on initiation of therapy.
Falls in platelet count, usually only to 80,000-90,000 per/mm3 but occasionally lower, have been reported in patients taking Tamoxifen for breast cancer.
A number of cases of visual disturbances including infrequent reports of corneal changes and retinopathy have been described in patients receiving Tamoxifen therapy. An increased incidence of cataracts has been reported in association with the administration of the drug. Uterine fibroids and endometrial changes including hyperplasia and polyps have been reported. Cystic ovarian swellings have occasionally been observed in premenopausal women receiving Tamoxifen.
Leucopenia has been observed following the administration of Tamoxifen, sometimes in association with anaemia and/or thrombocytopenia. Neutropenia has been reported on rare occasions; this can sometimes be severe. There is evidence of an increased incidence of thromboembolic events including deep vein thrombosis and pulmonary embolism during Tamoxifen therapy.
Tamoxifen has been associated with changes in liver enzyme levels and on rare occasions with a spectrum of more severe liver abnormalities, including fatty liver, cholestasis and hepatitis. Rarely, elevation of serum triglyceride levels, in some cases with pancreatitis, may be associated with the use of Tamoxifen.

ContraindicationsView
Tamoxifen must not be administered during pregnancy. Tamoxifen should not be given to patients who have experienced hypersensitivity to the product or any of its ingredients.
PrecautionsView
Menstruation is suppressed in a proportion of premenopausal women receiving Tamoxifen for the treatment of breast cancer. An increased incidence of endometrial cancer has seen reported in association with Tamoxifen treatment. The underlying mechanism is unknown, but may be related to the oestrogen-like effect of Tamoxifen. Any patients receiving or having previously received Tamoxifen, who report abnormal gynaecological symptoms, especially vaginal bleeding, should be promptly investigated.
A number of second primary tumors, occurring at sites other than the endometrium and the opposite breast, have been reported in clinical trials, following the treatment of breast cancer patients with Tamoxifen. No causal link has been established and the clinical significance of these observations remains unclear.

No causal link has been established and the clinical significance of these observations remains unclear.
InteractionsView
When Tamoxifen is used in combination with coumarin type anticoagulants, a significant increase in anticoagulant effect may occur. Where such co administration is initiated, careful monitoring of the patient is recommended. When Tamoxifen is used in combination with cytotoxic agents, there is an increased risk of thromboembolic events.
Pregnancy & lactationView
Pregnancy: Tamoxifen must not be administered during pregnancy. There have been a small number of reports of spontaneous abortions, birth defects and foetal deaths after women have taken Tamoxifen, although no causal relationship has been established. Reproductive toxicology studies in rats, rabbits and monkeys have shown no teratogenic potential.
Women should be advised not to become pregnant whilst taking Tamoxifen and should use barrier or other nonhormonal contraceptive methods if sexually active. Premenopausal patients must be carefully examined before treatment to exclude pregnancy. Women should be informed of the potential risks to the foetus, if they want to become pregnant whilst taking Tamoxifen or within two months of cessation of therapy.
Lactation: It is not known if Tamoxifen is excreted in human milk and therefore the drug is not recommended during lactation. The decision to discontinue Tamoxifen should take into account in case of the importance of the drug to the lactating mother.

Tamsin
Tamsulosin Hydrochloride
Tamsin
Tamsulosin Hydrochloride
Indications
Benign prostatic hyperplasia (BPH)
Indication detailsView
Tamsulosin Hydrochloride is indicated for the treatment of functional symptoms of Benign Prostatic Hyperplasia (BPH).
Therapeutic classView
BPH/ Urinary retention/ Urinary incontinence
PharmacologyView
Tamsulosin, a selective alpha1 adrenoceptor blocking agent, exhibits its selectivity for alpha1 A adrenoceptors in human prostate. Blockade of these adrenoceptors can cause smooth muscle in the bladder neck and prostate to relax, resulting in an improvement in urine flow rate and a reduction in symptoms of BPH. Absorption of Tamsulosin hydrochloride capsule 0.4mg is essentially complete (90%) following oral administration under fasting conditions. The time to maximum concentration (Tmax) is reached by four to five hours under fasting conditions and by six to seven hours when administered with food. Tamsulosin hydrochloride is extremely bound to human plasma protein (94% to 99%). Tamsulosin hydrochloride is extensively metabolized by cytochrome P 450 enzymes in the liver and less than 10% of the dose is excreted in urine as unchanged form. Following intravenous or oral administration of an immediate-release formulation the elimination half-life of Tamsulosin hydrochloride in plasma ranges from five to seven hours. Because of the absorption rate controlled pharmacokinetics with Prostam capsules, the apparent half-life of Tamsulosin hydrochloride is approximately 9 to 13 hours in healthy volunteers and 14 to 15 hours in the target population.
DosageView
Tamsulosin Hydrochloride 0.4 mg (one capsule) daily, to be taken after meal at night. The dose may be increased after 2 to 4 weeks, if necessary, to Tamsulosin Hydrochloride 0.8 mg (two capsules) once daily. If Tamsulosin Hydrochloride administration is discontinued or interrupted for several days at either the 0.4 mg or 0.8 mg dose, therapy should be started again with the Tamsulosin Hydrochloride 0.4 mg (one capsule) once daily dose. The capsule should be swallowed whole with a glass of water (about 150 ml) in the standing or sitting position. The capsule should not be crunched or chewed, as this will interfere with the modified release of the active ingredient.
Side effectsView
The following adverse reactions have been reported during the use of Tamsulosin: dizziness, abnormal ejaculation and; less frequently headache, asthenia, postural hypotension and palpitations.
ContraindicationsView
Tamsulosin hydrochloride is contraindicated in patients with hypersensitivity to it; history of orthostatic hypotension; severe hepatic insufficiency.
As with other alpha1 blockers, a reduction in blood pressure can occur in individual cases during treatment with Tamsulosin, as a result of which, rarely, syncope can occur, at the first signs of orthostatic hypotension (dizziness, weakness) the patient should sit or lie down until the symptoms have disappeared. And they should be cautioned to avoid situations where injury could result (like driving, operating machinery or performing hazardous tasks).
Before therapy with Tamsulosin is initiated the patient should be examined in order to exclude the presence of other conditions which can cause the same symptoms as Benign Prostatic hyperplasia. Digital rectal examination and when the necessary determination of Prostate Specific Antigen (PSA) should be performed before treatment and at regular intervals afterwards.

PrecautionsView
Rarely, transient postural symptoms have occurred during orthostatic provocation testing after the first dose. Use in patients with micturition syncope is not advised.
Effects on ability to drive and use machines: No data is available on whether Tamsulosin adversely affects the ability to drive or operate machines. However, in this respect, patients should be aware of the fact that dizziness can occur.

InteractionsView
Concurrent administration of other alfa1-adrenoceptor antagonists could lead to hypotensive effects. No interactions have been seen when Tamsulosin was given concomitantly with either atenolol, enalapril or nifedipine. Concomitant cimetidine brings about a rise and frusemide a fall in plasma levels of Tamsulosin, but as levels remain within the normal range posology need not be changed. No interactions at the level of hepatic metabolism have been seen during in vitro studies with liver microsomal fractions (representative of the cytochrome P450-linked drug-metabolizing enzyme system), involving amitriptyline, salbutamol, glibenclamide, and finasteride. Diclofenac and warfarin, however, may increase the elimination rate of Tamsulosin.
Pregnancy & lactationView
Use of Tamsulosin in pregnancy and lactation is not recommended.
Overdose effectsView
No case of acute overdosage has been reported. However, acute hypotension is likely to occur after overdosage in which case cardiovascular support should be given. Blood pressure can be restored and the heart rate brought back to normal by lying the patient down. If this does not help then volume expanders, and when necessary, vasopressors could be employed. Renal function should be monitored and general supportive measures applied. Dialysis is unlikely to be of help as Tamsulosin is very highly bound to plasma proteins. Measures, such as emesis, can be taken to impede absorption. When large quantities are involved, gastric lavage can be applied and activated charcoal and an osmotic laxative, such as sodium sulphate, can be administered.
StorageView
Store in a cool and dry place, below 30°C, protected from light.

- Treatment of moderate to severe symptoms of benign prostatic hyperplasia (BPH).
- Reduction in the risk of acute urinary retention and surgery in patients with moderate to severe symptoms of BPH.
Therapeutic classView
BPH/ Urinary retention/ Urinary incontinence
PharmacologyView
Tamsulosin & Dutasteride is a combination of two drugs with complementary mechanisms of action to improve symptoms in patients with Benign Prostatic Hyperplasia (BPH). Tamsulosin Hydrochloride, an antagonist of alpha1A-adrenoreceptors and Dutasteride, a dual 5 alpha reductase inhibitor (5ARI). Treatment of BPH with alpha1-adrenoreceptor blocking agents and 5ARIs results in an improvement in urine flow rate and a reduction in symptoms of BPH.
Tamsulosin: An alpha1-adrenoreceptor blocking agent that affects the dynamic component of BPH by inhibiting alpha1-adrenoreceptors in the stromal prostatic smooth muscle and bladder neck. Blockade of these adrenoreceptors can cause smooth muscles in the bladder neck and prostate to relax. Specifically, Tamsulosin exhibits selectivity for both alpha 1A and alpha 1D receptors over the alpha1B-adrenoreceptor subtype. These three adrenoreceptor subtypes have a distinct distribution pattern in human tissue. Whereas approximately 70% of the alpha1-receptors in human prostate are of the alpha 1A subtype, the human bladder contains predominantly the alpha 1D subtype while blood vessels express predominantly alpha 1B subtype. It is further believed that blockade of the alpha 1D subtypes in the human obstructed bladder may be responsible for reducing detrusor overactivity and subsequent relief of storage symptoms.
Dutasteride: A synthetic 4-azasteriod compound is a competitive and specific inhibitor of both Type I and Type II 5 alpha-reductase isoenzymes that affects the static component of BPH by inhibiting the conversion of Testosterone to Dihydrotestosterone (DHT) by the enzyme 5 alpha-reductase. 5 alpha-reductase exists as 2 isoforms, Type I and Type II, both of which are present in the prostate. It has been observed that compared to normal tissue, the expression of both isoenzymes are increased in BPH tissue. Dissociation from this complex has been evaluated under in vitro and in vivo conditions and is extremely slow. Dutasteride lowers DHT levels and leads to a reduction in prostatic volume, thereby treating an underlying cause of BPH. Dutasteride does not bind to the human androgen receptor.

DosageView
Adults (including elderly): The recommended dose is one capsule (Tamsulosin Hydrochloride 0.4 mg & Dutasteride 0.5 mg) taken orally approximately 30 minutes after the same meal each day. The capsules should be swallowed whole and not chewed or opened. Where appropriate, this capsule may be used to substitute concomitant Tamsulosin Hydrochloride and Dutasteride in existing dual therapy to simplify treatment. Where clinically appropriate, direct change from Tamsulosin Hydrochloride or Dutasteride monotherapy to this capsule may be considered.
Renal impairment: The effect of renal impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied. No adjustment in dosage is anticipated for patients with renal impairment.
Hepatic impairment: The effect of hepatic impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied so caution should be used in patients with mild to moderate hepatic impairment. In patients with severe hepatic impairment, the use of this capsule is contra-indicated.

Hepatic impairment: The effect of hepatic impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied so caution should be used in patients with mild to moderate hepatic impairment. In patients with severe hepatic impairment, the use of this capsule is contra-indicated.
Side effectsView
The most common adverse reactions reported in subjects receiving combination therapy were impotence, decreased libido, breast disorders (including breast enlargement and tenderness), ejaculation disorders and dizziness. The percentages of subjects with ejaculation disorders, decreased libido and impotence were higher in the combination therapy group compared with either monotherapy groups.
ContraindicationsView
Tamsulosin-Dutasteride combination is contra-indicated in women and children and adolescents, patients with hypersensitivity to Dutasteride, other 5-alpha reductase inhibitors, Tamsulosin (including Tamsulosin- induced angio-edema), soya, peanut or any of other the excipients, patients with a history of orthostatic hypotension and patients with severe hepatic impairment.
PrecautionsView
Combination therapy should be prescribed after careful benefit risk assessment due to the potential increased risk of adverse events (including cardiac failure) and after consideration of alternative treatment options including monotherapies.
Cardiac failure: In two 4-year clinical studies, the incidence of cardiac failure was higher among subjects taking the combination of Dutasteride and an alpha blocker, primarily Tamsulosin, than it was among subjects not taking the combination. In these two trials, the incidence of cardiac failure was low (1%) and variable between the studies.
Effects on prostate specific antigen (PSA) and prostate cancer detection: Digital rectal examination, as well as other evaluations for prostate cancer or other conditions which can cause the same symptoms as BPH, must be performed on patients prior to initiating therapy with Tamsulosin-Dutasteride combination and periodically thereafter. Serum prostate-specific antigen (PSA) concentration is an important component in the detection of prostate cancer. Tamsulosin-Dutasteride combination causes a decrease in mean serum PSA levels by approximately 50%, after 6 months of treatment. Patients receiving Tamsulosin-Dutasteride combination should have a new PSA baseline established after 6 months of treatment. It is recommended to monitor PSA values regularly thereafter. Any confirmed increase from lowest PSA level while on Tamsulosin-Dutasteride combination may signal the presence of prostate cancer or noncompliance to therapy with Tamsulosin-Dutasteride combination and should be carefully evaluated, even if those values are still within the normal range for men not taking a 5 alpha-reductase inhibitor. In the interpretation of a PSA value for a patient taking Tamsulosin-Dutasteride combination, previous PSA values while on Dutasteride treatment should be sought for comparison. Treatment with Tamsulosin-Dutasteride combination does not interfere with the use of PSA as a tool to assist in the diagnosis of prostate cancer after a new baseline has been established. Total serum PSA levels return to baseline within 6 months of discontinuing treatment. The ratio of free to total PSA remains constant even under the influence of Tamsulosin-Dutasteride combination. If clinicians elect to use percent free PSA as an aid in the detection of prostate cancer in men undergoing Tamsulosin-Dutasteride combination therapy, no adjustment to its value appears necessary.
Prostate cancer and high grade tumours: Results of one clinical study in men at increase risk of prostate cancer revealed a higher incidence of Gleason 8-10 prostate cancers in Dutasteride treated men compared to placebo. The relationship between Dutasteride and high grade prostate cancer is not clear. Men taking Tamsulosin-Dutasteride combination should be regularly evaluated for prostate cancer risk including PSA testing.
Renal impairment: The treatment of severely renally impaired patients (creatinine clearance of less than 10 ml/min) should be approached with caution as these patients have not been studied.
Hypotension: Orthostatic- As with other alpha-blockers, a reduction in blood pressure can occur during treatment with Tamsulosin, as a result of which, rarely, syncope can occur. Patients beginning treatment with Tamsulosin-Dutasteride combination should be cautioned to sit or lie down at the first signs of orthostatic hypotension (dizziness, weakness) until the symptoms have resolved. In order to minimize the potential for developing postural hypotension the patient should be haemodynamically stable on alpha-blocker therapy prior to initiating use of PDE5 inhibitors. Symptomatic: Caution is advised when alpha adrenergic blocking agents including Tamsulosin are coadministered with PDE5 inhibitors (e.g. sildenafil, tadalafil, vardenafil). Alpha adrenergic blockers and PDE5 inhibitors are both vasodilators that can lower blood pressure. Concomitant use of these two drug classes can potentially cause symptomatic hypotension.
Intraoperative Floppy Iris Syndrome: Intraoperative Floppy Iris Syndrome (IFIS) has been observed during cataract surgery in some patients on or previously treated with Tamsulosin. IFIS may lead to increased procedural complications during the operation. The initiation of therapy with Tamsulosin-Dutasteride combination in patients for whom cataract surgery is scheduled is therefore not recommended. Discontinuing Tamsulosin 1-2 weeks prior to cataract surgery is anecdotally considered helpful, but the benefit and duration of stopping therapy prior to cataract surgery has not yet been established. Leaking Capsule: Dutasteride is absorbed through the skin, therefore, women, children and adolescents must avoid contact with leaking capsules. If contact is made with leaking capsules, the contact area should be washed immediately with soap and water.
Hepatic impairment: Tamsulosin-Dutasteride combination has not been studied in patients with liver disease. Caution should be used in the administration of Tamsulosin-Dutasteride combination to patients with mild to moderate hepatic impairment.
Breast neoplasia: Breast cancer has been reported in men taking Dutasteride in clinical trials and during the post-marketing period. Physicians should instruct their patients to promptly report any changes in their breast tissue such as lumps or nipple discharge. Currently it is not clear if there is a causal relationship between the occurrence of male breast cancer and long term use of Dutasteride.
Cardiac failure: In two 4-year clinical studies, the incidence of cardiac failure was higher among subjects taking the combination of Dutasteride and an alpha blocker, primarily Tamsulosin, than it was among subjects not taking the combination. In these two trials, the incidence of cardiac failure was low (1%) and variable between the studies.

InteractionsView
There have been no drug interaction studies for Dutasteride-Tamsulosin combination.
Effects of other drugs on the pharmacokinetics of Dutasteride: Use together with CYP3A4 and/or P-glycoprotein-inhibitors: Dutasteride is mainly eliminated via metabolism. In vitro studies indicate that this metabolism is catalysed by CYP3A4 and CYP3A5. No formal interaction studies have been performed with potent CYP3A4 inhibitors. However, in a population pharmacokinetic study, Dutasteride serum concentrations were on average 1.6 to 1.8 times greater, respectively, in a small number of patients treated concurrently with verapamil or diltiazem (moderate inhibitors of CYP3A4 and inhibitors of P-glycoprotein) than in other patients. Long-term combination of Dutasteride with drugs that are potent inhibitors of the enzyme CYP3A4 (e.g. ritonavir, indinavir, nefazodone, itraconazole, ketoconazole administered orally) may increase serum concentrations of Dutasteride. Further inhibition of 5-alpha reductase at increased Dutasteride exposure, is not likely. However, a reduction of the Dutasteride dosing frequency can be considered if side effects are noted. It should be noted that in the case of enzyme inhibition, the long half-life may be further prolonged and it can take more than 6 months of concurrent therapy before a new steady state is reached. Administration of 12 g cholestyramine one hour after a 5 mg single dose of Dutasteride did not affect the pharmacokinetics of Dutasteride.
Effects of Dutasteride on the pharmacokinetics of other drugs: In a small study (N=24) of two weeks duration in healthy men, Dutasteride (0.5 mg daily) had no effect on the pharmacokinetics of Tamsulosin or terazosin. There was also no indication of a pharmacodynamic interaction in this study. Dutasteride has no effect on the pharmacokinetics of warfarin or digoxin. This indicates that Dutasteride does not inhibit/induce CYP2C9 or the transporter P-glycoprotein. In vitro interaction studies indicate that Dutasteride does not inhibit the enzymes CYP1A2, CYP2D6, CYP2C9, CYP2C19 or CYP3A4. Tamsulosin: Concomitant administration of Tamsulosin Hydrochloride with drugs which can reduce blood pressure, including anaesthetic agents, PDE5 inhibitors and other alpha-1 adrenergic blockers could lead to enhanced hypotensive effects. Tamsulosin-Dutasteride should not be used in combination with other alpha-1 adrenergic blockers. Concomitant administration of Tamsulosin Hydrochloride (0.4 mg) and cimetidine (400 mg every six hours for six days) resulted in a decrease in the clearance (26%) and an increase in the AUC (44%) of Tamsulosin Hydrochloride. Caution should be used when Tamsulosin-Dutasteride is used in combination with cimetidine. A definitive drug-drug interaction study between Tamsulosin Hydrochloride and warfarin has not been conducted. Results from limited in vitro and in vivo studies are inconclusive. Caution should be exercised with concomitant administration of warfarin and Tamsulosin Hydrochloride. No interactions have been seen when Tamsulosin Hydrochloride was given concomitantly with either atenolol, enalapril, nifedipine or theophylline. Concomitant furosemide brings about a fall in plasma levels of Tamsulosin, but as levels remain within the normal range posology need not be adjusted. In vitro neither diazepam nor propranolol, trichlormethiazide, chlormadinon, amitryptyline, diclofenac, glibenclamide and simvastatin change the free fraction of Tamsulosin in human plasma. Neither does Tamsulosin change the free fractions of diazepam, propranolol, trichlormethiazide, and chlormadinon. No interactions at the level of hepatic metabolism have been seen during in vitro studies with liver microsomal fractions, involving amitriptyline, salbutamol and glibenclamide. Diclofenac however, may increase the elimination rate of Tamsulosin.

It should be noted that in the case of enzyme inhibition, the long half-life may be further prolonged and it can take more than 6 months of concurrent therapy before a new steady state is reached. Administration of 12 g cholestyramine one hour after a 5 mg single dose of Dutasteride did not affect the pharmacokinetics of Dutasteride.
Effects of Dutasteride on the pharmacokinetics of other drugs: In a small study (N=24) of two weeks duration in healthy men, Dutasteride (0.5 mg daily) had no effect on the pharmacokinetics of Tamsulosin or terazosin. There was also no indication of a pharmacodynamic interaction in this study. Dutasteride has no effect on the pharmacokinetics of warfarin or digoxin. This indicates that Dutasteride does not inhibit/induce CYP2C9 or the transporter P-glycoprotein. In vitro interaction studies indicate that Dutasteride does not inhibit the enzymes CYP1A2, CYP2D6, CYP2C9, CYP2C19 or CYP3A4. Tamsulosin: Concomitant administration of Tamsulosin Hydrochloride with drugs which can reduce blood pressure, including anaesthetic agents, PDE5 inhibitors and other alpha-1 adrenergic blockers could lead to enhanced hypotensive effects. Tamsulosin-Dutasteride should not be used in combination with other alpha-1 adrenergic blockers. Concomitant administration of Tamsulosin Hydrochloride (0.4 mg) and cimetidine (400 mg every six hours for six days) resulted in a decrease in the clearance (26%) and an increase in the AUC (44%) of Tamsulosin Hydrochloride. Caution should be used when Tamsulosin-Dutasteride is used in combination with cimetidine. A definitive drug-drug interaction study between Tamsulosin Hydrochloride and warfarin has not been conducted. Results from limited in vitro and in vivo studies are inconclusive. Caution should be exercised with concomitant administration of warfarin and Tamsulosin Hydrochloride. No interactions have been seen when Tamsulosin Hydrochloride was given concomitantly with either atenolol, enalapril, nifedipine or theophylline. Concomitant furosemide brings about a fall in plasma levels of Tamsulosin, but as levels remain within the normal range posology need not be adjusted. In vitro neither diazepam nor propranolol, trichlormethiazide, chlormadinon, amitryptyline, diclofenac, glibenclamide and simvastatin change the free fraction of Tamsulosin in human plasma. Neither does Tamsulosin change the free fractions of diazepam, propranolol, trichlormethiazide, and chlormadinon. No interactions at the level of hepatic metabolism have been seen during in vitro studies with liver microsomal fractions, involving amitriptyline, salbutamol and glibenclamide. Diclofenac however, may increase the elimination rate of Tamsulosin.
Pregnancy & lactationView
Tamsulosin-Dutasteride combination is contra-indicated for use by women. There have been no studies to investigate the effect of Tamsulosin-Dutasteride combination on pregnancy, lactation and fertility. The following statements reflect the information available from studies with the individual components. Fertility: Dutasteride has been reported to affect semen characteristics (reduction in sperm count, semen volume, and sperm motility) in healthy men. The possibility of reduced male fertility cannot be excluded. Effects of Tamsulosin Hydrochloride on sperm counts or sperm function have not been evaluated.
Pregnancy: As with other 5 alpha reductase inhibitors, Dutasteride inhibits the conversion of testosterone to dihydrotestosterone and may, if administered to a woman carrying a male foetus, inhibit the development of the external genitalia of the foetus. Small amounts of Dutasteride have been recovered from the semen in subjects receiving Dutasteride. It is not known whether a male foetus will be adversely affected if his mother is exposed to the semen of a patient being treated with Dutasteride. As with all 5 alpha reductase inhibitors, when the patient’s partner is or may potentially be pregnant it is recommended that the patient avoids exposure of his partner to semen by use of a condom. Administration of Tamsulosin Hydrochloride to pregnant female rats and rabbits showed no evidence of foetal harm.
Lactation: It is not known whether Tamsulosin or Dutasteride are excreted in human milk.

Overdose effectsView
No data are available with regard to over dosage of Tamsulosin-Dutasteride combination. The following statements reflect the information available on the individual components.
Dutasteride: In volunteer studies, single daily doses of Dutasteride up to 40 mg/day (80 times the therapeutic dose) have been administered for 7 days without significant safety concerns. In clinical studies, doses of 5 mg daily have been administered to subjects for 6 months with no additional adverse effects to those seen at therapeutic doses of 0.5 mg. There is no specific antidote for Dutasteride, therefore, in suspected over dosage symptomatic and supportive treatment should be given as appropriate.
Tamsulosin: Acute overdose with 5 mg Tamsulosin Hydrochloride has been reported. Acute hypotension (systolic blood pressure 70 mm Hg), vomiting and diarrhoea were observed which were treated with fluid replacement and the patient could be discharged the same day. In case of acute hypotension occurring after over dosage cardiovascular support should be given. Blood pressure can be restored and heart rate brought back to normal by lying the patient down. If this does not help then volume expanders, and when necessary, vasopressors could be employed. Renal function should be monitored and general supportive measures applied. Dialysis is unlikely to be of help as Tamsulosin is very highly bound to plasma proteins. Measures, such as emesis, can be taken to impede absorption. When large quantities are involved, gastric lavage can be applied and activated charcoal and an osmotic laxative, such as sodium sulphate, can be administered.

Tamsulosin Hydrochloride
Indications
Benign prostatic hyperplasia (BPH)
Indication detailsView
Tamsulosin Hydrochloride is indicated for the treatment of functional symptoms of Benign Prostatic Hyperplasia (BPH).
Therapeutic classView
BPH/ Urinary retention/ Urinary incontinence
PharmacologyView
Tamsulosin, a selective alpha1 adrenoceptor blocking agent, exhibits its selectivity for alpha1 A adrenoceptors in human prostate. Blockade of these adrenoceptors can cause smooth muscle in the bladder neck and prostate to relax, resulting in an improvement in urine flow rate and a reduction in symptoms of BPH. Absorption of Tamsulosin hydrochloride capsule 0.4mg is essentially complete (90%) following oral administration under fasting conditions. The time to maximum concentration (Tmax) is reached by four to five hours under fasting conditions and by six to seven hours when administered with food. Tamsulosin hydrochloride is extremely bound to human plasma protein (94% to 99%). Tamsulosin hydrochloride is extensively metabolized by cytochrome P 450 enzymes in the liver and less than 10% of the dose is excreted in urine as unchanged form. Following intravenous or oral administration of an immediate-release formulation the elimination half-life of Tamsulosin hydrochloride in plasma ranges from five to seven hours. Because of the absorption rate controlled pharmacokinetics with Prostam capsules, the apparent half-life of Tamsulosin hydrochloride is approximately 9 to 13 hours in healthy volunteers and 14 to 15 hours in the target population.
DosageView
Tamsulosin Hydrochloride 0.4 mg (one capsule) daily, to be taken after meal at night. The dose may be increased after 2 to 4 weeks, if necessary, to Tamsulosin Hydrochloride 0.8 mg (two capsules) once daily. If Tamsulosin Hydrochloride administration is discontinued or interrupted for several days at either the 0.4 mg or 0.8 mg dose, therapy should be started again with the Tamsulosin Hydrochloride 0.4 mg (one capsule) once daily dose. The capsule should be swallowed whole with a glass of water (about 150 ml) in the standing or sitting position. The capsule should not be crunched or chewed, as this will interfere with the modified release of the active ingredient.
Side effectsView
The following adverse reactions have been reported during the use of Tamsulosin: dizziness, abnormal ejaculation and; less frequently headache, asthenia, postural hypotension and palpitations.
ContraindicationsView
Tamsulosin hydrochloride is contraindicated in patients with hypersensitivity to it; history of orthostatic hypotension; severe hepatic insufficiency.
As with other alpha1 blockers, a reduction in blood pressure can occur in individual cases during treatment with Tamsulosin, as a result of which, rarely, syncope can occur, at the first signs of orthostatic hypotension (dizziness, weakness) the patient should sit or lie down until the symptoms have disappeared. And they should be cautioned to avoid situations where injury could result (like driving, operating machinery or performing hazardous tasks).
Before therapy with Tamsulosin is initiated the patient should be examined in order to exclude the presence of other conditions which can cause the same symptoms as Benign Prostatic hyperplasia. Digital rectal examination and when the necessary determination of Prostate Specific Antigen (PSA) should be performed before treatment and at regular intervals afterwards.

- Reduction in the risk of acute urinary retention and surgery in patients with moderate to severe symptoms of BPH.
Therapeutic classView
BPH/ Urinary retention/ Urinary incontinence
PharmacologyView
Tamsulosin & Dutasteride is a combination of two drugs with complementary mechanisms of action to improve symptoms in patients with Benign Prostatic Hyperplasia (BPH). Tamsulosin Hydrochloride, an antagonist of alpha1A-adrenoreceptors and Dutasteride, a dual 5 alpha reductase inhibitor (5ARI). Treatment of BPH with alpha1-adrenoreceptor blocking agents and 5ARIs results in an improvement in urine flow rate and a reduction in symptoms of BPH.
Tamsulosin: An alpha1-adrenoreceptor blocking agent that affects the dynamic component of BPH by inhibiting alpha1-adrenoreceptors in the stromal prostatic smooth muscle and bladder neck. Blockade of these adrenoreceptors can cause smooth muscles in the bladder neck and prostate to relax. Specifically, Tamsulosin exhibits selectivity for both alpha 1A and alpha 1D receptors over the alpha1B-adrenoreceptor subtype. These three adrenoreceptor subtypes have a distinct distribution pattern in human tissue. Whereas approximately 70% of the alpha1-receptors in human prostate are of the alpha 1A subtype, the human bladder contains predominantly the alpha 1D subtype while blood vessels express predominantly alpha 1B subtype. It is further believed that blockade of the alpha 1D subtypes in the human obstructed bladder may be responsible for reducing detrusor overactivity and subsequent relief of storage symptoms.
Dutasteride: A synthetic 4-azasteriod compound is a competitive and specific inhibitor of both Type I and Type II 5 alpha-reductase isoenzymes that affects the static component of BPH by inhibiting the conversion of Testosterone to Dihydrotestosterone (DHT) by the enzyme 5 alpha-reductase. 5 alpha-reductase exists as 2 isoforms, Type I and Type II, both of which are present in the prostate. It has been observed that compared to normal tissue, the expression of both isoenzymes are increased in BPH tissue. Dissociation from this complex has been evaluated under in vitro and in vivo conditions and is extremely slow. Dutasteride lowers DHT levels and leads to a reduction in prostatic volume, thereby treating an underlying cause of BPH. Dutasteride does not bind to the human androgen receptor.

DosageView
Adults (including elderly): The recommended dose is one capsule (Tamsulosin Hydrochloride 0.4 mg & Dutasteride 0.5 mg) taken orally approximately 30 minutes after the same meal each day. The capsules should be swallowed whole and not chewed or opened. Where appropriate, this capsule may be used to substitute concomitant Tamsulosin Hydrochloride and Dutasteride in existing dual therapy to simplify treatment. Where clinically appropriate, direct change from Tamsulosin Hydrochloride or Dutasteride monotherapy to this capsule may be considered.
Renal impairment: The effect of renal impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied. No adjustment in dosage is anticipated for patients with renal impairment.
Hepatic impairment: The effect of hepatic impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied so caution should be used in patients with mild to moderate hepatic impairment. In patients with severe hepatic impairment, the use of this capsule is contra-indicated.

Hepatic impairment: The effect of hepatic impairment on Tamsulosin-Dutasteride pharmacokinetics has not been studied so caution should be used in patients with mild to moderate hepatic impairment. In patients with severe hepatic impairment, the use of this capsule is contra-indicated.
Side effectsView
The most common adverse reactions reported in subjects receiving combination therapy were impotence, decreased libido, breast disorders (including breast enlargement and tenderness), ejaculation disorders and dizziness. The percentages of subjects with ejaculation disorders, decreased libido and impotence were higher in the combination therapy group compared with either monotherapy groups.
ContraindicationsView
Tamsulosin-Dutasteride combination is contra-indicated in women and children and adolescents, patients with hypersensitivity to Dutasteride, other 5-alpha reductase inhibitors, Tamsulosin (including Tamsulosin- induced angio-edema), soya, peanut or any of other the excipients, patients with a history of orthostatic hypotension and patients with severe hepatic impairment.
PrecautionsView
Combination therapy should be prescribed after careful benefit risk assessment due to the potential increased risk of adverse events (including cardiac failure) and after consideration of alternative treatment options including monotherapies.
Cardiac failure: In two 4-year clinical studies, the incidence of cardiac failure was higher among subjects taking the combination of Dutasteride and an alpha blocker, primarily Tamsulosin, than it was among subjects not taking the combination. In these two trials, the incidence of cardiac failure was low (1%) and variable between the studies.
Effects on prostate specific antigen (PSA) and prostate cancer detection: Digital rectal examination, as well as other evaluations for prostate cancer or other conditions which can cause the same symptoms as BPH, must be performed on patients prior to initiating therapy with Tamsulosin-Dutasteride combination and periodically thereafter. Serum prostate-specific antigen (PSA) concentration is an important component in the detection of prostate cancer. Tamsulosin-Dutasteride combination causes a decrease in mean serum PSA levels by approximately 50%, after 6 months of treatment. Patients receiving Tamsulosin-Dutasteride combination should have a new PSA baseline established after 6 months of treatment. It is recommended to monitor PSA values regularly thereafter. Any confirmed increase from lowest PSA level while on Tamsulosin-Dutasteride combination may signal the presence of prostate cancer or noncompliance to therapy with Tamsulosin-Dutasteride combination and should be carefully evaluated, even if those values are still within the normal range for men not taking a 5 alpha-reductase inhibitor. In the interpretation of a PSA value for a patient taking Tamsulosin-Dutasteride combination, previous PSA values while on Dutasteride treatment should be sought for comparison. Treatment with Tamsulosin-Dutasteride combination does not interfere with the use of PSA as a tool to assist in the diagnosis of prostate cancer after a new baseline has been established. Total serum PSA levels return to baseline within 6 months of discontinuing treatment. The ratio of free to total PSA remains constant even under the influence of Tamsulosin-Dutasteride combination. If clinicians elect to use percent free PSA as an aid in the detection of prostate cancer in men undergoing Tamsulosin-Dutasteride combination therapy, no adjustment to its value appears necessary.
Prostate cancer and high grade tumours: Results of one clinical study in men at increase risk of prostate cancer revealed a higher incidence of Gleason 8-10 prostate cancers in Dutasteride treated men compared to placebo. The relationship between Dutasteride and high grade prostate cancer is not clear. Men taking Tamsulosin-Dutasteride combination should be regularly evaluated for prostate cancer risk including PSA testing.
Renal impairment: The treatment of severely renally impaired patients (creatinine clearance of less than 10 ml/min) should be approached with caution as these patients have not been studied.
Hypotension: Orthostatic- As with other alpha-blockers, a reduction in blood pressure can occur during treatment with Tamsulosin, as a result of which, rarely, syncope can occur. Patients beginning treatment with Tamsulosin-Dutasteride combination should be cautioned to sit or lie down at the first signs of orthostatic hypotension (dizziness, weakness) until the symptoms have resolved. In order to minimize the potential for developing postural hypotension the patient should be haemodynamically stable on alpha-blocker therapy prior to initiating use of PDE5 inhibitors. Symptomatic: Caution is advised when alpha adrenergic blocking agents including Tamsulosin are coadministered with PDE5 inhibitors (e.g. sildenafil, tadalafil, vardenafil). Alpha adrenergic blockers and PDE5 inhibitors are both vasodilators that can lower blood pressure. Concomitant use of these two drug classes can potentially cause symptomatic hypotension.
Intraoperative Floppy Iris Syndrome: Intraoperative Floppy Iris Syndrome (IFIS) has been observed during cataract surgery in some patients on or previously treated with Tamsulosin. IFIS may lead to increased procedural complications during the operation. The initiation of therapy with Tamsulosin-Dutasteride combination in patients for whom cataract surgery is scheduled is therefore not recommended. Discontinuing Tamsulosin 1-2 weeks prior to cataract surgery is anecdotally considered helpful, but the benefit and duration of stopping therapy prior to cataract surgery has not yet been established. Leaking Capsule: Dutasteride is absorbed through the skin, therefore, women, children and adolescents must avoid contact with leaking capsules. If contact is made with leaking capsules, the contact area should be washed immediately with soap and water.
Hepatic impairment: Tamsulosin-Dutasteride combination has not been studied in patients with liver disease. Caution should be used in the administration of Tamsulosin-Dutasteride combination to patients with mild to moderate hepatic impairment.
Breast neoplasia: Breast cancer has been reported in men taking Dutasteride in clinical trials and during the post-marketing period. Physicians should instruct their patients to promptly report any changes in their breast tissue such as lumps or nipple discharge. Currently it is not clear if there is a causal relationship between the occurrence of male breast cancer and long term use of Dutasteride.
Cardiac failure: In two 4-year clinical studies, the incidence of cardiac failure was higher among subjects taking the combination of Dutasteride and an alpha blocker, primarily Tamsulosin, than it was among subjects not taking the combination. In these two trials, the incidence of cardiac failure was low (1%) and variable between the studies.
Effects on prostate specific antigen (PSA) and prostate cancer detection: Digital rectal examination, as well as other evaluations for prostate cancer or other conditions which can cause the same symptoms as BPH, must be performed on patients prior to initiating therapy with Tamsulosin-Dutasteride combination and periodically thereafter. Serum prostate-specific antigen (PSA) concentration is an important component in the detection of prostate cancer. Tamsulosin-Dutasteride combination causes a decrease in mean serum PSA levels by approximately 50%, after 6 months of treatment. Patients receiving Tamsulosin-Dutasteride combination should have a new PSA baseline established after 6 months of treatment. It is recommended to monitor PSA values regularly thereafter. Any confirmed increase from lowest PSA level while on Tamsulosin-Dutasteride combination may signal the presence of prostate cancer or noncompliance to therapy with Tamsulosin-Dutasteride combination and should be carefully evaluated, even if those values are still within the normal range for men not taking a 5 alpha-reductase inhibitor.

InteractionsView
There have been no drug interaction studies for Dutasteride-Tamsulosin combination.
Effects of other drugs on the pharmacokinetics of Dutasteride: Use together with CYP3A4 and/or P-glycoprotein-inhibitors: Dutasteride is mainly eliminated via metabolism. In vitro studies indicate that this metabolism is catalysed by CYP3A4 and CYP3A5. No formal interaction studies have been performed with potent CYP3A4 inhibitors. However, in a population pharmacokinetic study, Dutasteride serum concentrations were on average 1.6 to 1.8 times greater, respectively, in a small number of patients treated concurrently with verapamil or diltiazem (moderate inhibitors of CYP3A4 and inhibitors of P-glycoprotein) than in other patients. Long-term combination of Dutasteride with drugs that are potent inhibitors of the enzyme CYP3A4 (e.g. ritonavir, indinavir, nefazodone, itraconazole, ketoconazole administered orally) may increase serum concentrations of Dutasteride. Further inhibition of 5-alpha reductase at increased Dutasteride exposure, is not likely. However, a reduction of the Dutasteride dosing frequency can be considered if side effects are noted. It should be noted that in the case of enzyme inhibition, the long half-life may be further prolonged and it can take more than 6 months of concurrent therapy before a new steady state is reached. Administration of 12 g cholestyramine one hour after a 5 mg single dose of Dutasteride did not affect the pharmacokinetics of Dutasteride.
Effects of Dutasteride on the pharmacokinetics of other drugs: In a small study (N=24) of two weeks duration in healthy men, Dutasteride (0.5 mg daily) had no effect on the pharmacokinetics of Tamsulosin or terazosin. There was also no indication of a pharmacodynamic interaction in this study. Dutasteride has no effect on the pharmacokinetics of warfarin or digoxin. This indicates that Dutasteride does not inhibit/induce CYP2C9 or the transporter P-glycoprotein. In vitro interaction studies indicate that Dutasteride does not inhibit the enzymes CYP1A2, CYP2D6, CYP2C9, CYP2C19 or CYP3A4. Tamsulosin: Concomitant administration of Tamsulosin Hydrochloride with drugs which can reduce blood pressure, including anaesthetic agents, PDE5 inhibitors and other alpha-1 adrenergic blockers could lead to enhanced hypotensive effects. Tamsulosin-Dutasteride should not be used in combination with other alpha-1 adrenergic blockers. Concomitant administration of Tamsulosin Hydrochloride (0.4 mg) and cimetidine (400 mg every six hours for six days) resulted in a decrease in the clearance (26%) and an increase in the AUC (44%) of Tamsulosin Hydrochloride. Caution should be used when Tamsulosin-Dutasteride is used in combination with cimetidine. A definitive drug-drug interaction study between Tamsulosin Hydrochloride and warfarin has not been conducted. Results from limited in vitro and in vivo studies are inconclusive. Caution should be exercised with concomitant administration of warfarin and Tamsulosin Hydrochloride. No interactions have been seen when Tamsulosin Hydrochloride was given concomitantly with either atenolol, enalapril, nifedipine or theophylline. Concomitant furosemide brings about a fall in plasma levels of Tamsulosin, but as levels remain within the normal range posology need not be adjusted. In vitro neither diazepam nor propranolol, trichlormethiazide, chlormadinon, amitryptyline, diclofenac, glibenclamide and simvastatin change the free fraction of Tamsulosin in human plasma. Neither does Tamsulosin change the free fractions of diazepam, propranolol, trichlormethiazide, and chlormadinon. No interactions at the level of hepatic metabolism have been seen during in vitro studies with liver microsomal fractions, involving amitriptyline, salbutamol and glibenclamide. Diclofenac however, may increase the elimination rate of Tamsulosin.

Pregnancy & lactationView
Tamsulosin-Dutasteride combination is contra-indicated for use by women. There have been no studies to investigate the effect of Tamsulosin-Dutasteride combination on pregnancy, lactation and fertility. The following statements reflect the information available from studies with the individual components. Fertility: Dutasteride has been reported to affect semen characteristics (reduction in sperm count, semen volume, and sperm motility) in healthy men. The possibility of reduced male fertility cannot be excluded. Effects of Tamsulosin Hydrochloride on sperm counts or sperm function have not been evaluated.
Pregnancy: As with other 5 alpha reductase inhibitors, Dutasteride inhibits the conversion of testosterone to dihydrotestosterone and may, if administered to a woman carrying a male foetus, inhibit the development of the external genitalia of the foetus. Small amounts of Dutasteride have been recovered from the semen in subjects receiving Dutasteride. It is not known whether a male foetus will be adversely affected if his mother is exposed to the semen of a patient being treated with Dutasteride. As with all 5 alpha reductase inhibitors, when the patient’s partner is or may potentially be pregnant it is recommended that the patient avoids exposure of his partner to semen by use of a condom. Administration of Tamsulosin Hydrochloride to pregnant female rats and rabbits showed no evidence of foetal harm.
Lactation: It is not known whether Tamsulosin or Dutasteride are excreted in human milk.

Overdose effectsView
No data are available with regard to over dosage of Tamsulosin-Dutasteride combination. The following statements reflect the information available on the individual components.
Dutasteride: In volunteer studies, single daily doses of Dutasteride up to 40 mg/day (80 times the therapeutic dose) have been administered for 7 days without significant safety concerns. In clinical studies, doses of 5 mg daily have been administered to subjects for 6 months with no additional adverse effects to those seen at therapeutic doses of 0.5 mg. There is no specific antidote for Dutasteride, therefore, in suspected over dosage symptomatic and supportive treatment should be given as appropriate.
Tamsulosin: Acute overdose with 5 mg Tamsulosin Hydrochloride has been reported. Acute hypotension (systolic blood pressure 70 mm Hg), vomiting and diarrhoea were observed which were treated with fluid replacement and the patient could be discharged the same day. In case of acute hypotension occurring after over dosage cardiovascular support should be given. Blood pressure can be restored and heart rate brought back to normal by lying the patient down. If this does not help then volume expanders, and when necessary, vasopressors could be employed. Renal function should be monitored and general supportive measures applied. Dialysis is unlikely to be of help as Tamsulosin is very highly bound to plasma proteins. Measures, such as emesis, can be taken to impede absorption. When large quantities are involved, gastric lavage can be applied and activated charcoal and an osmotic laxative, such as sodium sulphate, can be administered.

Tamurin
Tamsulosin Hydrochloride
Indications
Benign prostatic hyperplasia (BPH)
Indication detailsView
Tamsulosin Hydrochloride is indicated for the treatment of functional symptoms of Benign Prostatic Hyperplasia (BPH).
Therapeutic classView
BPH/ Urinary retention/ Urinary incontinence
PharmacologyView
Tamsulosin, a selective alpha1 adrenoceptor blocking agent, exhibits its selectivity for alpha1 A adrenoceptors in human prostate. Blockade of these adrenoceptors can cause smooth muscle in the bladder neck and prostate to relax, resulting in an improvement in urine flow rate and a reduction in symptoms of BPH. Absorption of Tamsulosin hydrochloride capsule 0.4mg is essentially complete (90%) following oral administration under fasting conditions. The time to maximum concentration (Tmax) is reached by four to five hours under fasting conditions and by six to seven hours when administered with food. Tamsulosin hydrochloride is extremely bound to human plasma protein (94% to 99%). Tamsulosin hydrochloride is extensively metabolized by cytochrome P 450 enzymes in the liver and less than 10% of the dose is excreted in urine as unchanged form. Following intravenous or oral administration of an immediate-release formulation the elimination half-life of Tamsulosin hydrochloride in plasma ranges from five to seven hours. Because of the absorption rate controlled pharmacokinetics with Prostam capsules, the apparent half-life of Tamsulosin hydrochloride is approximately 9 to 13 hours in healthy volunteers and 14 to 15 hours in the target population.
DosageView
Tamsulosin Hydrochloride 0.4 mg (one capsule) daily, to be taken after meal at night. The dose may be increased after 2 to 4 weeks, if necessary, to Tamsulosin Hydrochloride 0.8 mg (two capsules) once daily. If Tamsulosin Hydrochloride administration is discontinued or interrupted for several days at either the 0.4 mg or 0.8 mg dose, therapy should be started again with the Tamsulosin Hydrochloride 0.4 mg (one capsule) once daily dose. The capsule should be swallowed whole with a glass of water (about 150 ml) in the standing or sitting position. The capsule should not be crunched or chewed, as this will interfere with the modified release of the active ingredient.
Side effectsView
The following adverse reactions have been reported during the use of Tamsulosin: dizziness, abnormal ejaculation and; less frequently headache, asthenia, postural hypotension and palpitations.
ContraindicationsView
Tamsulosin hydrochloride is contraindicated in patients with hypersensitivity to it; history of orthostatic hypotension; severe hepatic insufficiency.
As with other alpha1 blockers, a reduction in blood pressure can occur in individual cases during treatment with Tamsulosin, as a result of which, rarely, syncope can occur, at the first signs of orthostatic hypotension (dizziness, weakness) the patient should sit or lie down until the symptoms have disappeared. And they should be cautioned to avoid situations where injury could result (like driving, operating machinery or performing hazardous tasks).
Before therapy with Tamsulosin is initiated the patient should be examined in order to exclude the presence of other conditions which can cause the same symptoms as Benign Prostatic hyperplasia. Digital rectal examination and when the necessary determination of Prostate Specific Antigen (PSA) should be performed before treatment and at regular intervals afterwards.

PrecautionsView
Rarely, transient postural symptoms have occurred during orthostatic provocation testing after the first dose. Use in patients with micturition syncope is not advised.
Effects on ability to drive and use machines: No data is available on whether Tamsulosin adversely affects the ability to drive or operate machines. However, in this respect, patients should be aware of the fact that dizziness can occur.

InteractionsView
Concurrent administration of other alfa1-adrenoceptor antagonists could lead to hypotensive effects. No interactions have been seen when Tamsulosin was given concomitantly with either atenolol, enalapril or nifedipine. Concomitant cimetidine brings about a rise and frusemide a fall in plasma levels of Tamsulosin, but as levels remain within the normal range posology need not be changed. No interactions at the level of hepatic metabolism have been seen during in vitro studies with liver microsomal fractions (representative of the cytochrome P450-linked drug-metabolizing enzyme system), involving amitriptyline, salbutamol, glibenclamide, and finasteride. Diclofenac and warfarin, however, may increase the elimination rate of Tamsulosin.
Pregnancy & lactationView
Use of Tamsulosin in pregnancy and lactation is not recommended.
Overdose effectsView
No case of acute overdosage has been reported. However, acute hypotension is likely to occur after overdosage in which case cardiovascular support should be given. Blood pressure can be restored and the heart rate brought back to normal by lying the patient down. If this does not help then volume expanders, and when necessary, vasopressors could be employed. Renal function should be monitored and general supportive measures applied. Dialysis is unlikely to be of help as Tamsulosin is very highly bound to plasma proteins.

Paracetamol
Indications
Toothache
Indication detailsView
Paracetamol is indicated for fever, common cold and influenza, headache, toothache, earache, bodyache, myalgia, neuralgia, dysmenorrhoea, sprains, colic pain, back pain, post-operative pain, postpartum pain, inflammatory pain and post vaccination pain in children. It is also indicated for rheumatic & osteoarthritic pain and stiffness of joints.
Therapeutic classView
Non opioid analgesics
PharmacologyView
Paracetamol has analgesic and antipyretic properties with weak anti-inflammatory activity. Paracetamol (Acetaminophen) is thought to act primarily in the CNS, increasing the pain threshold by inhibiting both isoforms of cyclooxygenase, COX-1, COX-2, and COX-3 enzymes involved in prostaglandin (PG) synthesis. Paracetamol is a para aminophenol derivative, has analgesic and antipyretic properties with weak anti-inflammatory activity. Paracetamol is one of the most widely used, safest and fast acting analgesic. It is well tolerated and free from various side effects of aspirin.
DosageView
Tablet:
- Adult: 1-2 tablets every 4 to 6 hours up to a maximum of 4 gm (8 tablets) daily.
- Children (6-12 years): ½ to 1 tablet 3 to 4 times daily. For long term treatment it is wise not to exceed the dose beyond 2.6 gm/day.

Side effectsView
Side effects of paracetamol are usually mild, though haematological reactions including thrombocytopenia, leucopenia, pancytopenia, neutropenia, and agranulocytosis have been reported. Pancreatitis, skin rashes, and other allergic reactions occur occasionally.
ContraindicationsView
It is contraindicated in known hypersensitivity to Paracetamol.
PrecautionsView
Paracetamol should be given with caution to patients with impaired kidney or liver function. Paracetamol should be given with care to patients taking other drugs that affect the liver.
InteractionsView
Patients who have taken barbiturates, tricyclic antidepressants and alcohol may show diminished ability to metabolise large doses of Paracetamol. Alcohol can increase the hepatotoxicity of Paracetamol overdosage. Chronic ingestion of anticonvulsants or oral steroid contraceptives induce liver enzymes and may prevent attainment of therapeutic Paracetamol levels by increasing first-pass metabolism or clearance.
Pregnancy & lactationView
Pregnancy category B according to USFDA. This drug should be used during pregnancy only if clearly needed
Overdose effectsView
Symptoms of Paracetamol overdose in the first 24 hours are pallor, nausea, vomiting, anorexia and abdominal pain. Liver damage may become apparent 12-48 hours after ingestion. Abnormalities of glucose metabolism and metabolic acidosis may occur.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

Betacarotene + Vitamin C + Vitamin E
Tanox
Betacarotene + Vitamin C + Vitamin E
Indications
Vitamin deficiency
Indication detailsView
Antioxidant vitamins are used in a wide range of conditions where free radical damage is playing a role. Antioxidant vitamin combination is used in the prevention of coronary heart diseases, certain types of cancer, aging as well as free radical damage caused by excessive exercise, illness, certain medications, air pollution, smoke, radiation and pesticides. The main role of the antioxidant vitamins is as follows:
β carotene prevents free radical formation by quenching singlet oxygen, a highly reactive form of oxygen. Vitamin C is another free radical scavenger which deactivates free radicals. It works specially in the plasma, lung fluid, aqueous humour and interstitial fluid. It can increase white blood cell activity; play important roles in the biochemistry of antibodies, prostaglandin E 1 , B and T lymphocytes, and interferon. Vitamin E also scavenges free radicals in the blood along with β carotene and vitamin C. Moreover, vitamin E is essential to protect against some of the ill effects of smog and smoke. In relation to other nutrients vitamin E protects vitamin A from being destroyed in the body.

Anti-oxidant Multivitamin preparations
PharmacologyView
Beta carotene of this tablet is converted to vitamin A (Retinol) when required. Retinol has several biochemical functions e.g. on retina, growth, tissue differentiation, immunological response. It has also some anti-cancer activity.
Vitamin C is the most powerful reducing agent known to be present in living tissues. Vitamin C deficiency produces scurvy. It is a cofactor in numerous biological processes. Vitamin C and molecular oxygen are essential for the conversion of proline to hydroxyproline, dopamine to noradrenaline . Vitamin C is also essential for the synthesis of adrenal steroid hormones. Vitamin C is important in the defense against infection and studies shown that vitamin C is important for the normal functioning of T-lymphocyte and leukocyte. Ascorbic acid has some antiinflammatory activity and protects cells against oxidation of essential molecules. In high doses, (1-2 g daily) ascorbic acid increases iron absorption.
vitamin E seems to be as a defense against oxidative stress and lipid peroxidation. In most cell membranes there is one molecule of tocopherol for every 1000 lipid molecules. Tocopherol mops up peroxide radicals and then needs a supply of reduced hydrogen to restore the steady-state situation. This is usually supplied by ascorbic acid or reduced glutathione.

DosageView
This tablet is administered orally. The adult dose of this combination of antioxidant vitamin tablet is 1 tablet daily or as prescribed by the physician.
Side effectsView
β carotene is comparatively safe even at high and prolonged exposure. Individuals who routinely ingest large amounts of carotenoids can develop hypercarotenosis, which is characterised by a yellowish colouration of the skin and a very high concentration of carotenoids in the plasma. This benign condition, although resembling jaundice, gradually disappears upon correcting the excessive intake of carotenoids.
Vitamin C is generally a safe drug for human use in normal doses. Larger doses may lead to gastrointestinal tract upset and renal stone formation.
Vitamin E is considered safe even in large doses. Doses over 800 mg may cause diarrhoea, abdominal pain or cramps, fatigue and reduced resistance to bacterial infection and transiently raised blood pressure.

Vitamin E is considered safe even in large doses. Doses over 800 mg may cause diarrhoea, abdominal pain or cramps, fatigue and reduced resistance to bacterial infection and transiently raised blood pressure.
ContraindicationsView
Carocet is contraindicated in patients with hypersensitivity to any of its components.
PrecautionsView
There are some evidences that β carotene may cause harm to heavy smokers and alcoholics. Therefore, caution should be exercised in these cases. Vitamin C should be given with caution to patients with hyperoxaluria. Vitamin E should be used with caution in patients taking anticoagulant drugs, because vitamin E may enhance the anticoagulant activity of these drugs.
InteractionsView
Cholestyramine, Colestipol, Neomycin cause decreased absorption of β carotene. Circulating vitamin C levels have been shown to be reduced during prolonged administration of oral contraceptives containing Oestrogen, Tetracycline and Aspirin. The decrease in vitamin C level may be due to drug induced impaired absorption or increased utilization of the vitamin for drug metabolism. Vitamin E may enhance the anticoagulant activity of anticoagulant drugs. High doses of vitamin E can impair intestinal absorption of vitamins A and K.
Pregnancy & lactationView
β carotene, vitamin C and vitamin E have no teratogenic effects in humans. However, like any other drugs caution should be taken in prescribing to pregnant women.
StorageView
Should be stored in a dry place below 30˚C.

PharmacologyView
Vitamin A is essential for human health. Vitamin A is highly important for vision, cell development and immunity. Vitamin A's role on immunity contributes to its anti-cancer properties.
Vitamin C is one of the most widely taken supplements and plays a primary role in the formation of collagen, which is important for the growth and repair of cells, gums, blood vessels, bones and teeth. Thus vitamin C helps in faster recovery after surgery or any other trauma. Vitamin C quenches free radicals in the water based cellular components and thus acts as an antioxidant.
Vitamin E is a fat-soluble vitamin, which is stored in the liver, adipose tissues, heart, muscles etc. It is an active antioxidant, which prevents oxidation of fat compounds. It works in synergy with Selenium.
Vitamin K is a key anti-aging vitamin and it prevents heart disease and osteoporosis.
Zinc is an important mineral that can actually rejuvenate the shrinking thymus gland that involves the working of the immune system. Zinc is a co-factor in over 100 enzymes of the body.
Selenium: Apart from being a co-factor in antioxidant enzymes, Selenium by itself has potent antioxidant capabilities. So, it prevents aging and hardening of tissues through oxidation. Vitamin E and Selenium are synergistic and seem to potentiate each other's antioxidant activities.
Copper is an important co-factor of a number of enzymes present in our body. This enzymes act as endogenous antioxidant systems.
Manganese, an antioxidant, is one of the minerals required to form SOD (Super Oxide Dismutase). SOD is an enzyme that protect against cell damaging free radicals.

Therapeutic classView
Angiotensin-ll receptor blocker
PharmacologyView
Losartan Potassium is the first non-peptide orally active angiotensin II receptor blocker. It binds to the AT1 receptor found in many tissues (e.g. vascular smooth muscle, adrenal gland, kidneys and the heart) and reduces several important biological actions including vasoconstriction and the release of aldosterone responsible for hypertension.
DosageView
The usual starting and maintenance dose is 50 mg once daily for most patients. If the antihypertensive effect using 50 mg once daily is inadequate, 25 mg twice daily is recommended prior to increasing the dose. For patients with intravascular volume-depletion (e.g., those treated with high-dose diuretics), a starting dose of 25 mg once daily should be considered. Losartan Potassium can be administered once or twice daily. The total daily dose ranges from 25 mg to 100 mg.
Side effectsView
The side effects with the use of Losartan Potassium are mild and transient in nature. The most common side effects are dizziness, diarrhea, nasal congestion, cough, upper respiratory infection. Other side effects are fatigue, oedema, abdominal pain, chest pain, nausea, headache & pharyngitis.
ContraindicationsView
Losartan Potassium is contraindicated in pregnant women and in patients who are hypersensitive to any component of this product. Losartan Potassium should not be administered with Aliskiren in patients with diabetes.
PrecautionsView
Use of Losartan Potassium during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. In patients who are intravascularly volume-depleted (e.g., those treated with high-dose diuretics), symptomatic hypotension may occur. Plasma concentration of Losartan Potassium is significantly increased in cirrhotic patients. Changes in renal function including renal failure have been reported in renal impaired patient.
InteractionsView
Rifampicin and fluconazole reduce levels of active metabolite of Losartan Potassium. Concomitant use of Losartan Potassium and hydrochlorothiazide may lead to potentiation of the antihypertensive effects. Concomitant use of potassium-sparing diuretics (eg, spironolactone, triamterene, amiloride), potassium supplements or salt substitutes containing potassium may lead to increases in serum potassium. The antihypertensive effect of losartan may be attenuated by the non-steroidal anti-inflammatory drug indomethacin. The use of ACE-inhibitor, angiotensin receptor antagonist, an anti-inflammatory drug and a thiazide diuretic at the same time increases the risk of renal impairment.
Pregnancy & lactationView
Pregnancy Category D. The risk to the fetus increases if Losartan Potassium is administered during the second or third trimesters of pregnancy. It is not known whether Losartan Potassium is excreted in human milk, as many drugs are excreted in human milk and because of the potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Losartan Potassium + Hydrochlorothiazide
Indications
Stroke
Indication detailsView
This is indicated for the treatment of hypertension. It is also indicated to reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy.
Therapeutic classView
Combined antihypertensive preparations
PharmacologyView
Angiotensin II formed from angiotensin I in a reaction catalyzed by angiotensin converting enzyme (ACE), is a potent vasoconstrictor, the primary vasoactive hormone of the renin-angiotensin system and an important component in the pathophysiology of hypertension. It also stimulates aldosterone secretion by the adrenal cortex. Losartan and its principal active metabolite block the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor found in many tissues, (e.g. vascular smooth muscle, adrenal gland). In vitro binding studies indicate that losartan is a reversible, competitive inhibitor of the AT1 receptor. Neither Losartan nor its active metabolite inhibits ACE (kinase II, the enzyme that converts angiotensin I to angiotensin II and degrades bradykinin); nor do they bind to or block other hormone receptors or ion channels known to be important in cardiovascular regulation.
Hydrochlorothiazide is a thiazide diuretic. Thiazides affect the renal tubular mechanisms of electrolyte reabsorption, directly increasing excretion of Sodium and Chloride in approximately equivalent amounts. Indirectly, the diuretic action of Hydrochlorothiazide reduces plasma volume, with consequent increases in plasma renin activity, increases in Aldosterone secretion, increases in urinary Potassium loss, and decreases in serum Potassium. The renin-aldosterone link is mediated by angiotensin II, so co-administration of an angiotensin II receptor antagonist tends to reverse the Potassium loss associated with these diuretics.

DosageView
Hypertension-
- The usual starting dose of 50/12.5 is one tablet once daily.
- For patients who do not respond adequately to one tablet the dosage may be increased to 100/25 once daily.
- A patient whose blood pressure is not adequately controlled with Losartan 100 mg monotherapy may be switched to this combination 100/12.5 once daily.
- In hypertensive patients with left ventricular hypertrophy initial dose is 50/12.5, if additional blood pressure reduction is needed, 100/12.5 may be given, followed by 100/25 if required. The maximum dose is 100/25 once daily.
- In general, the antihypertensive effect is attained within three weeks after initiation of therapy.
- No initial dosage adjustment of 50/12.5 is necessary for elderly patients. But maximum dose of 100/25 once daily dose should not be used as initial therapy in elderly patients.
- The starting dose for initial treatment of severe hypertension is one tablet of 50/12.5 once daily.
- For patients who do not respond adequately to this dose after 2 to 4 weeks of therapy, the dosage may be increased to 100/25 once daily. The maximum dose is one tablet of 100/25 once daily.
AdministrationView
This preparation may be administered with other antihypertensive agents. This may be administered with or without food.
Side effectsView
Side-effects are usually mild. Symptomatic hypotension including dizziness may occur, particularly in patients with intravascular volume depletion (e.g. those taking high-dose diuretics). Hyperkalaemia occurs occasionally; angioedema has also been reported with some angiotensin-II receptor antagonists. Vertigo; less commonly gastro-intestinal disturbances, angina, palpitation, oedema, dyspnoea, headache, sleep disorders, malaise, urticaria, pruritus, rash; rarely hepatitis, atrial fibrillation, cerebrovascular accident, syncope, paraesthesia; also reported pancreatitis, anaphylaxis, cough, depression, erectile dysfunction, anaemia, thrombocytopenia, hyponatraemia, arthralgia, myalgia, renal impairment, rhabdomyolysis, tinnitus, photosensitivity, and vasculitis (including Henoch-Schonlein purpura)
ContraindicationsView
The combination of Losartan and Hydrochlorothiazide is contraindicated in patients who are hypersensitive to any component of this product. Because of the Hydrochlorothiazide component, this product is contraindicated in patients with anuria or hypersensitivity to other sulfonamide-derived drugs.
PrecautionsView
- Hypersensitivity: Angiooedema
- Periodic determination of serum electrolytes to detect possible electrolyte imbalance should be performed at appropriate intervals
- Hypokalemia may rarely develop, especially with brisk diuresis, when severe cirrhosis is present, or after prolonged therapy
- Impaired renal function and
- Symptomatic hypotension
InteractionsView
Losartan Potassium: No significant drug-drug pharmacokinetic interactions have been found in interaction studies with Hydrochlorothiazide, Digoxin, Warfarin, Cimetidine and Phenobarbital. As with other drugs that block angiotensin II or its effects, concomitant use of potassium-sparing diuretics (e.g. Spironolactone, Triamterene, Amiloride), potassium supplements, or salt substitutes containing potassium may lead to increase in serum potassium. As with other antihypertensive agents, the antihypertensive effect of Losartan may be blunted by the non-steroidal anti-inflammatory drug Indomethacin.
Hydrochlorothiazide: When administered concurrently, the following drugs may interact with Thiazide diuretics: alcohol, barbiturates, or narcotics-potentiation of orthostatic hypotension may occur.
Antidiabetic drugs (oral agents and Insulin): dosage adjustment of the antidiabetic drug may be required.
Other antihypertensive drugs: additive effect or potentiation.
Cholestyramine and colestipol resins: absorption of Hydrochlorothiazide is impaired in the presence of anionic exchange resins

Pregnancy & lactationView
Angiotensin-II receptor antagonists should be avoided in pregnancy unless essential. They may adversely affect fetal and neonatal blood pressure control and renal function; skull defects and oligohy dramnios have also been reported. Information on the use of angiotensin-II receptor antagonists in breastfeeding is limited. They are not recommended in breastfeeding and alternative treatment options, with better-established safety information during breastfeeding, are available.
Pediatric usageView
Use in Patients with Renal Impairment: The usual regimens of therapy with 50/12.5 may be followed as long as the patient's creatinine clearance is >30 ml/min. In patients with more severe renal impairment, loop diuretics are preferred to thiazides. In that case, hydrochlorothiazide is not recommended.
Use in Patients with Hepatic Impairment: The combination of Losartan and Hydrochlorothiazide is not recommended for titration in patients with hepatic impairment because the appropriate 25 mg starting dose of Losartan cannot be given.
Use in pediatric patients: The safety and effectiveness in pediatric patients have not been established.
Use in Patients with Hepatic Impairment: The combination of Losartan and Hydrochlorothiazide is not recommended for titration in patients with hepatic impairment because the appropriate 25 mg starting dose of Losartan cannot be given.
Use in pediatric patients: The safety and effectiveness in pediatric patients have not been established.
Overdose effectsView
Losartan Potassium: Limited data are available in regard to overdosage in humans. The most likely manifestation of overdosage would be hypotension and tachycardia; bradycardia could occur from parasympathetic (vagal) stimulation. If symptomatic hypotension should occur, supportive treatment should be instituted. Neither losartan nor its metabolite can be removed by hemodialysis.
Hydrochlorothiazide: The most common signs and symptoms observed are those caused by electrolyte depletion (hypokalemia, hypochloremia, and dehydration resulting from excessive diuresis. If digitalis has also been administered, hypokalemia, may accentuate cardiac arrhythmias. The degree to which Hydrochlorothiazide is removed by hemodialysis has not been established.

The recommended dose in adults is 80 mg taken orally once daily. Consider a Starting dose of 40 mg for patients who are treated with high doses of diuretics. If blood pressure is not controlled with Azilsartan alone, additional blood pressure reduction can be achieved by taking Azilsartan with other antihypertensive agents.
Side effectsView
The most common adverse reaction in adults is diarrhea. The other side effects are nausea, asthenia, fatigue, muscle spasm, dizziness and cough.
ContraindicationsView
It is contraindicated to co-administer Aliskiren with Azilsartan in patients with Diabetes.
PrecautionsView
Use of Azilsartan Medoxomil during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. In patients who are intravascularly volume-depleted (e.g., those treated with high-dose diuretics), symptomatic hypotension may occur. Changes in renal function including renal failure has been reported in renal impaired patient.
InteractionsView
No drug interactions have been observed in studies of Azilsartan Medoxomil or Azilsartan given with amlodipine, antacids, chlorthalidone, digoxin, fluconazole, glyburide, ketoconazole, metformin, pioglitazone and warfarin. The antihypertensive effect of Azilsartan may be attenuated by the non-steroidal anti-inflammatory drugs including selective COX-2 inhibitors. Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors or aliskiren is associated with increased risks of hypotension, hyperkalemia and changes in renal function.
Pregnancy & lactationView
Pregnancy Category D. The risk to the fetus increases if Azilsartan Medoxomil is administered during the second or third trimesters of pregnancy. It is not known whether Azilsartan Medoxomil is excreted in human milk, as many drugs are excreted in human milk and because of the potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric usageView
Safety and effectiveness in pediatric patients under 18 years of ages have not been established.
Overdose effectsView
Limited data are available related to overdose in humans. In the event of and overdose, supportive therapy should be instituted as dictated by the patient’s clinical status. Azilsartan is not dialyzable.
StorageView
keep in a dry place away from light and heat. Keep out of the reach of children.

Indications
Pain
Indication detailsView
Tapentadol is indicated for the relief of moderate to severe acute pain in patients 18 years of age or older.
Therapeutic classView
Opioid analgesics
PharmacologyView
Tapentadol is a centrally-acting synthetic analgesic. It is 18 times less potent than morphine in terms of binding to human mu-opioid receptors. It also increases norepinephrine concentrations in the brains of rats via inhibition of norepinephrine reuptake. Selective mu-opioid antagonists like naloxone can block analgesia from tapentadol. It also has not effect on the QT interval.
Tapendadol causes large increases in levels of extracellular norepinephrine (NE) due to a dual mechanism of action involving mu opioid receptor (MOR) agonism as well as noradrenaline reuptake inhibition.

DosageView
As with many centrally-acting analgesic medications, the dosing regimen should be individualized according to the severity of pain being treated, the previous experience with similar drugs and the ability to monitor the patient.
The dose is 50 mg, 75 mg, or 100 mg every 4 to 6 hours depending upon pain intensity. On the first day of dosing, the second dose may be administered as soon as one hour after the first dose, if adequate pain relief is not attained with the first dose. Subsequent dosing is 50 mg, 75 mg, or 100 mg every 4 to 6 hours and should be adjusted to maintain adequate analgesia with acceptable tolerability.
Daily doses greater than 700 mg on the first day of therapy and 600 mg on subsequent days have not been studied and are not recommended.

Side effectsView
The following treatment-emergent adverse events may happen: heart rate increased, heart rate decreased, visual disturbance, abdominal discomfort, impaired gastric emptying, irritability, edema, drug withdrawal syndrome, hypersensitivity, involuntary muscle contractions, sensation of heaviness, hypoesthesia, paresthesia, disturbance in attention, sedation, dysarthria, memory impairment, ataxia, presyncope, syncope, coordination abnormal, seizure, urticaria, blood pressure decreased etc.
ContraindicationsView
This drug is contraindicated in patients with impaired Pulmonary Function, It is also contraindicated in patients with acute or severe bronchial asthma or hypercapnia in unmonitored settings or the absence of resuscitative equipment. This drug is contraindicated in any patient who has or is suspected of having paralytic ileus.
PrecautionsView
Tapentadol should be administered with caution to patients with conditions accompanied by hypoxia, hypercapnia respiratory problems such as: asthma, chronic obstructive pulmonary disease etc. Besides this in case of patient with sleep apnea syndrome, myxedema, kyphoscoliosis, central nervous system (CNS) depression should have to be cautious prior administration of Tapentadol. Patients receiving other mu-opioid agonist analgesics, general anesthetics, phenothiazines, other tranquilizers, sedatives, hypnotics, or other CNS depressants (including alcohol) concomitantly with Tapentadol may exhibit additive CNS depression.
InteractionsView
Increased risk of serotonin syndrome with other drugs that enhance monoaminergic neurotransmission (e.g. TCAs, triptans, SSRIs, serotonin and norepinephrine reuptake inhibitors). Enhanced sedative effect with benzodiazepines, barbiturates, antipsychotics, H1-antihistamines and other opioids. Increased potential for addiction with mixed μ-opioid agonists/antagonists (e.g. nalbuphine, pentazocine) or partial μ-opioid agonists (e.g. buprenorphine). Increased systemic exposure with strong inhibitors of UGT1A6, UGT1A9 and UGT2B7 isoenzymes. Decreased efficacy with strong enzyme inducers (e.g. rifampicin, phenobarbital).
