Amino acid is indicated as a source of amino acids for protein synthesis in patients needing intravenous nutrition. Amino acid is particularly suitable for patients with basal amino acid requirements. Amino acid is also indicated in faster recovery in surgery, burns, renal insufficiency, hepatic insufficiency and effective management of cancer.

Parenteral nutritional preparations

This IV solution is a sterile aqueous solution of crystalline Amino Acid and D-Sorbitol with electrolytes, which are necessary as the nitrogen source for parenteral nutrition. Nitrogen provided in the form of essential and non-essential amino acids. This IV solution contains all 18 essential and non-essential amino acids needed for protein synthesis. The amino acid composition is such that positive nitrogen balance can be achieved in the postoperative period and during extended periods of intravenous nutrition. The solution is clear, colorless to pale yellow colored, having a p H lying in the range of 5.0 to 7.0.

The nitrogen requirement for maintenance of body protein mass depends on the patient's condition (nutritional state and degree of metabolic stress).

• No or minor metabolic stress and normal nutritional state: 0.10-0.15 g nitrogen/kg/day, 
• Moderate metabolic stress with or without malnutrition: 0.15-0.20 g nitrogen/kg/day, 
• Severe catabolism as in burns, sepsis and trauma: up to 0.20-0.25 g nitrogen/kg/day. 

The dosage range 0.10-0.25 g nitrogen/kg/day corresponds to 15-35 ml Amino acids IV/kg/day. 

In obese patients, the dose should be based on the estimated ideal weight. Depending upon patients requirements, 1000-2000 ml Amino acids IV may be infused intravenously per 24 hours. Amino acids IV should be infused slowly, at rates 1.4-2.8 ml (30-60 drops) per minute.

In children and infants: The rate of infusion is 28-35 ml/kg body weight per day is recommended, with a step-wise increase in the rate of administration during the frst week.

This preparation is usually well tolerated. Nausea occurs rarely. Vomiting, flushing and sweating have been observed during infusion of Amino acid at rates exceeding the recommended maximal rate. Transient increases liver test during intravenous nutrition have been reported. The reasons are at present unclear. Hypersensitivity reactions have been reported. As with all hypertonic infusion solutions, thrombophlebitis may occur when peripheral veins are used. The incidence may be reduced by the simultaneous infusion of 10% fat emulsion. If given to severely ill, premature infants, hyperphenylalaninemia may occur.

This is contraindicated in patients with inborn errors of amino acids metabolism, severe liver dysfunction and in severe uremia when dialysis facilities are not available. Due to the content of glucose, Amino Acids IV infusion and 10% Glucose with Electrolytes is contraindicated in patients with hyperosmolar nonketotic diabetic coma.

IV infusion of amino acids is accompanied by increased urinary excretion of the trace elements copper and in particular zinc, which should be taken into account in the dosing of trace elements, particularly during long-term IV nutrition. Hyperphenylalaninemia may occur in severely ill, premature infants. In these patients, monitoring of the phenylalanine level is recommended and the infusion rate adjusted as needed. Amino Acids IV infusion and 10% Glucose with Electrolytes should be used with caution in patients with diabetes mellitus, severe heart failure or with renal function in combination with fluid restrictions or oliguria/anuria of another origin. In patients with hyperglycemia, administration of exogenous insulin might be necessary. In severely malnourished patients refeeding carbohydrates can trigger thiamine (vitamin B1 ) deficiency syndrome. Those at high risk are patients with a history of alcohol abuse, anorexia nervosa, prolonged fasting or starvation and pregnant women with hyperemesis gravidarum. In this kind of patients, parenteral nutrition containing glucose should be given with caution and parenteral administration of thiamine should be considered before and during the administration of glucose. Monitoring of serum potassium and blood glucose is recommended if Amino Acids IV infusion and 10% Glucose with electrolytes is infused rapidly or in a large quantity. For patients with hypophosphatemia, an additional supply of phosphate is recommended.

At the recommended dosage the amino acid have no pharmacological effects and is not expected to interact with other medicaments.

Successful and safe administration of amino acid solutions during pregnancy in the human has been reported. Animal reproduction studies have not been carried out with Amino acid.

If Amino Acids IV infusion and 10% Glucose with Electrolytes is administered at a higher rate than recommended, there is an augmented risk for nausea, vomiting and sweating. When peripheral veins are used thrombophlebitis may occur. Osmotic diuresis with dehydration may occur if the dosage recommendations are exceeded. There is also a risk of symptoms related to hyperglycemia with Amino Acids IV infusion and 10% Glucose with Electrolytes. In case of symptoms due to overdose, the infusion should be slowed down or discontinued.

Protect from light and store between 15°C to 25°C temperature. Avoid freezing. Keep out of reach of children.

This is indicated in urination problems in benign prostatic hyperplasia stages I & II.

Tamsulosin Hydrochloride is indicated for the treatment of functional symptoms of Benign Prostatic Hyperplasia (BPH).

BPH/ Urinary retention/ Urinary incontinence

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.

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.

The following adverse reactions have been reported during the use of Tamsulosin: dizziness, abnormal ejaculation and; less frequently headache, asthenia, postural hypotension and palpitations.

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.

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.

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.

Use of Tamsulosin in pregnancy and lactation is not recommended.

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.

Store in a cool and dry place, below 30°C, protected from light.

Tamsulosin Hydrochloride & Dutasteride capsule is indicated in-

• 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.

BPH/ Urinary retention/ Urinary incontinence

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 alpha_1A-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 alpha_1B-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.

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.

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.

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.

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.

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.

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.

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.

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.

The following adverse reactions have been reported during the use of Tamsulosin: dizziness, abnormal ejaculation and; less frequently headache, asthenia, postural hypotension and palpitations.

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.

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.

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.

Use of Tamsulosin in pregnancy and lactation is not recommended.

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.

Store in a cool and dry place, below 30°C, protected from light.

BPH/ Urinary retention/ Urinary incontinence

Silodosin is a selective antagonist of post-synaptic alpha-1 adrenoreceptors, which are located in the human prostate, bladder base, bladder neck, prostatic capsule and prostatic urethra. Blockade of these alpha-1 adrenoreceptors can cause smooth muscle in these tissues to relax, resulting in an improvement in urine flow and a reduction in BPH symptoms.

The recommended dose is Silodosin 8 mg orally once daily with a meal. 4 mg capsules taken orally once daily with a meal for those with moderate renal impairment (CrCl 30-50 mL/min).

Most common adverse reactions are retrograde ejaculation, dizziness, diarrhea, orthostatic hypotension, headache, nasopharyngitis and nasal congestion.

Patients with severe renal & hepatic impairment, concomitant administration with strong Cytochrome P450 3A4 (CYP3A4) inhibitors (e.g., ketoconazole, clarithromycin, itraconazole, ritonavir) and patients with a history of hypersensitivity to Silodosin.

Postural hypotension with or without symptoms (e.g. dizziness) may develop when beginning Silodosin treatment. Silodosin should not be used in combination with other alpha-blocker. Inform patients planning cataract surgery to notify their ophthalmologist that they are taking Silodosin because of the possibility of Intraoperative Floppy Iris Syndrome (IFIS)

Strong P-glycoprotein inhibitors (e.g., cyclosporine): Co-administration may increase plasma Silodosin concentration. Concomitant use of PDE5 inhibitors with alpha-blockers including Silodosin can potentially cause symptomatic hypotension.

Pregnancy Category B. Silodosin is not indicated for use in women. An embryo/fetal study in rabbits showed decreased maternal body weight at 200 mg/kg/day (approximately 13-25 times the maximum recommended human exposure or MRHE of Silodosin via AUC). No statistically significant teratogenicity was observed at this dose. Silodosin was not teratogenic when administered to pregnant rats during organogenesis at 1000 mg/kg/day (estimated to be approximately 20 times the MRHE). No maternal or fetal effects were observed at this dose. Rats and rabbits do not produce glucuronidated Silodosin, which is present in human serum at approximately 4 times the level of circulating Silodosin and which has similar pharmacological activity to Silodosin. No effects on physical or behavioral development of offspring were observed when rats were treated during pregnancy and lactation at up to 300 mg/kg/day.

Pediatric patients: Silodosin is not indicated for use in pediatric patients.

Geriatric use: In double-blind, placebo-controlled, 12-week clinical studies of Silodosin, 259 (55.6%) were under 65 years of age, 207 (44.4%) patients were 65 years of age and over, while 60 (12.9%) patients were 75 years of age and over. Orthostatic hypotension was reported in 2.3% of Silodosin patients < 65 years of age (1.2% for placebo), 2.9% of Silodosin patients > 65 years of age (1.9% for placebo), and 5.0% of patients > 75 years of age (0% for placebo). There were otherwise no significant differences in safety or effectiveness between older and younger patients.

Renal impairment: Silodosin is contra-indicated in patients with severe renal impairment (CCr <30 mL/min). In patients with moderate renal impairment (CCr 30-50 mL/min), the dose should be reduced to Silodosin 4 mg once daily taken with a meal. No dosage adjustment is needed in patients with mild renal impairment (CCr 50-80 mL/min).

Hepatic impairment: Silodosin has not been studied in patients with severe hepatic impairment (Child-Pugh score >10) and is therefore contra-indicated in these patients. No dosage adjustment is needed in patients with mild or moderate hepatic impairment.

Silodosin was evaluated at doses of up to 48 mg/day in healthy male subjects. The dose-limiting adverse event was postural hypotension. Should overdose of Silodosin lead to hypotension, support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by maintaining the patient in the supine position. If this measure is inadequate, administration of intravenous fluid should be considered. If necessary, vasopressors could be used, and renal function should be monitored and supported as needed. Dialysis is unlikely to be of significant benefit since Silodosin is highly (97%) protein bound.

Store at below 30°C in a dry place protected from light. Keep out of reach of Children.

Anti-cholinesterases, Drugs used in Myasthenia Gravis

Neostigmine is a parasympathomimetic, specifically, a reversible cholinesterase inhibitor. By interfering with the breakdown of acetylcholine, Neostigmine indirectly stimulates both nicotinic and muscarinic receptors. It does cross the blood-brain barrier but only poorly. Neostigmine binds to the anionic site of cholinesterase. The drug blocks the active site of acetylcholinesterase; so the enzyme can no longer break down the acetylcholine molecules before they reach the postsynaptic membrane receptors. This allows for the threshold to be reached so a new impulse can be triggered in the next neuron. In myasthenia gravis there are too few acetylcholine receptors. So with the acetylcholinesterase blocked, acetylcholine can bind to the few receptors and trigger a muscular contraction.

Reversal of the effects of Non-depolarizing Neurormuscular Blocking Agents: The usual dose is 0.5 to 2 mg given by slow intravenous injection over 60 seconds; repeated as required. Total dose should not exceed 5 mg (in exceptional cases). When Neostigmine is administered intravenously, it is recommended that Atropine Sulphate (0.6-1.2 mg) also be given intravenously using separate syringe.

Prevention of post-operative abdominal distention and urinary retention: 0.25 mg intramuscularly or subcutaneously as soon as possible after operation; repeat every 4 6 hours for 2-3 days.

Treatment of post-operative abdominal distention: 0.5 mg intramuscularly or subcutaneously or as required.

Treatment of urinary retention: 0.5 mg intramuscularly or subcutaneously. If urination does not occur within an hour, the patient should be catheterized. After the patient has voided, or the bladder has been emptied, continue the 0.5 mg injection every 3 hours, for at least 5 injections.

Symptomatic control of Myasthenia Gravis: 0.5 mg intramuscularly or subcutaneously. Subsequent dose should be based on the individual patient's response.

Neonates: 50-250 micrograms (0.1 to 0.5 ml) every 4 hours.

Children: 200-500 micrograms (0.4 ml to 1 ml) as recommended.

Nausea, vomiting, increased salivation, diarrhoea and abdominal cramps (more marked with high doses). Signs of overdose are increased gastrointestinal discomfort, bronchial secretions and sweating, involuntary defecation and micturition, miosis, nystagmus, bradycardia, hypotension, agitation, excessive dreaming and weakness eventually leading to fasciculation and paralysis.

Neostigmine is contraindicated in patients with known hypersensitivity to the drug. It is also contraindicated in patients with peritonitis or mechanical obstruction of the intestinal or urinary tract.

Asthma, bradycardia, recent myocardial infarction, epilepsy, hypotension, parkinsonism, vagotonia, peptic ulceration. Atropine or other antidote to muscarinic effccts may be necessary (particularly when Neostigmine is given by injection), but it should not be given routinely as it may mask signs of overdose.

Anti-arrhythmic Procainamide, Quinidine and possibly Propafenone antagonise effect of Neostigmine. Antibacterials, Aminoglycosides, Clindamycin, Lincomycin and Polymyxins antagonise effect of Neostigmine.

Pregnancy Category C. There are no adequate or well-controlled studies of Neostigmine in either laboratory animals or in pregnantwomen. It is not known whether Neostigmine can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Neostigmine should be given to a pregnant woman only if clearly needed.

Nonteratogenic Effects: Anticholinesterase drugs may cause uterine irritability and induce premature labor when given intravenously to pregnant women near term.

Nursing Mothers: It is not known whether Neostigmine is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions from Neostigmine in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Store in a cool and dry place, protected from light.

Terazosin Hydrochloride is indicated in-

• Single therapy is used to relieve from signs and symptoms of benign prostatic hyperplasia (BPH).
• For the treatment of hypertension.

Alpha adrenoceptor blocking drugs, BPH/ Urinary retention/ Urinary incontinence

Terazosin is selective for alpha-1-adrenoceptors but not their individual subtypes. Inhibition of these alpha-1-adrenoceptors results in relaxation of smooth muscle in blood vessels and the prostate, lowering blood pressure and improving urinary flow. Smooth muscle cells accounts for roughly 40% of the volume of the prostate and so their relaxation reduces pressure on the urethra.

It has also been shown that catecholamines induce factors responsible for mitogenesis and alpha-1-adrenergic receptor blockers inhibit this effect. A final long term mechanism of terazosin and other alpha-1-adrenergic receptor blockers is the induction of apoptosis of prostate cells. Treatment with terazosin enhances the expression of transforming growth factor beta-1 (TGF-beta1), which upregulates p27kip1, and the caspase cascade

Benign Prostatic Hyperplasia-

• Initial dose: 1 mg at bedtime is starting dose of all patients and this dose should not be exceeded.
• Subsequent dose: The dose slowly increases to achieve the desired response. The usual recommended dose range is 5-10 mg administered once a day.

Hypertension-

• Initial dose: 1 mg at bedtime is starting dose of all patients and this dose should not be exceeded.
• Subsequent dose: The dose slowly increases to achieve the desired response. The usual recommended dose range is 2-10 mg administered once a day.

Postural hypotension is more commonly reported side effect. Dizziness, lack of energy, peripheral oedema; urinary frequency and priapism reported.

Terazosin is contraindicated in patients known to be hypersensitive to Terazosin or its analogues.

The safety of Terazosin during pregnancy has not been established. So Terazosin is not recommended during pregnancy unless the potential benefit justifies the potential risk to mother and fetus. It is not known whether Terazosin is excreted in breast milk. As many drugs are excreted in breast milk, caution should be exercised when Terazosin is administered to a nursing mother.

Acute overdose may lead to acute hypotension, cardiovascular support is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in a supine position. At the same time expansion of plasma volume and noradrenergic vasopressor may also be needed.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Tamsulosin Hydrochloride is indicated for the treatment of functional symptoms of Benign Prostatic Hyperplasia (BPH).

BPH/ Urinary retention/ Urinary incontinence

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.

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.

Tamsulosin Hydrochloride & Dutasteride capsule is indicated in-

• 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.

BPH/ Urinary retention/ Urinary incontinence

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 alpha_1A-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 alpha_1B-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.

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.

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.

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.

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.

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.

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.

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.

Store in a cool and dry place, protected from light.

Angiotensin-converting enzyme (ACE) inhibitors

Ramipril is an angiotensin converting enzyme (ACE) inhibitor, which after hydrolysis to ramiprilat, blocks the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. So, inhibition of ACE by ramipril results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and decreased aldosterone secretion. Thus ramipril exerts its antihypertensive activity. It is also effective in the management of heart failure and reduction of the risk of stroke, myocardial infarction and death from cardiovascular events. It is long acting and well tolerated; so, can be used in long term therapy.

Dosage of Ramipril must be adjusted according to the patient tolerance and response.

Hypertension: For the management of hypertension in adults not receiving a diuretic, the usual initial dose of Ramipril is 1.25-2.5 mg once daily. Dosage generally is adjusted no more rapidly than at 2 week intervals. The usual maintenance dosage in adults is 2.5-20 mg daily given as a single dose or in 2 divided doses daily. If BP is not controlled with Ramipril alone, a diuretic may be added.

Congestive heart failure after myocardial infarction: In this case, Ramipril therapy may be initiated as early as 2 days after myocardial infarction. An initial dose of 2.5 mg twice daily is recommended, but if hypotension occurs, dose should be reduced to 1.25 mg twice daily. Therapy is then titrated to a target daily dose of 5 mg twice daily.

Prevention of major cardiovascular events: In this case, the recommended dose is 2.5 mg once daily for the first week of therapy and 5 mg once daily for the following 3 weeks; dosage then may be increased, as tolerated, to a maintenance dosage of 10 mg once daily.

Dosage in renal impairment:

• For patients with hypertension and renal impairment: The recommended initial dose is 1.25 mg Ramipril once daily. Subsequent dosage should be titrated according to individual tolerance and BP response, up to a maximum of 5 mg daily.
• For patients with heart failure and renal impairment: The recommended dose is 1.25 mg once daily. The dose may be increased to 1.25 mg twice daily and up to a maximum dose of 2.5 mg twice daily depending upon clinical response and tolerability.

Ramipril tablets have to be swallowed with sufficient amounts of liquid. The tablets must not be chewed or crushed. Absorption of Ramipril is not significantly affected by food. Ramipril may, therefore, be taken before, during or after a meal.

Ramipril is generally well tolerated. Dizziness, headache, fatigue and asthenia are commonly reported side effects. Other side effects occurring less frequently include symptomatic hypotension, cough, nausea, vomiting, diarrhoea, rash, urticaria, oliguria, anxiety, amnesia etc. Angioneurotic oedema, anaphylactic reactions and hyperkalaemia have also been reported rarely.

Ramipril must not be used

• in patients with hypersensitivity to ramipril, to any other ACE inhibitor, or any of the excipients of Ramipril.
• in patients with a history of angioedema.
• concomitantly with sacubitril/valsartan therapy. Do not initiate Ramipril until sacubitril/valsartan is eliminated from the body. In case of switch from Ramipril to sacubitril/valsartan, do not start sacubitril/valsartan until Ramipril is eliminated from the body.
• in patients with haemodynamically relevant renal artery stenosis, bilateral or unilateral in the single kidney.
• in patients with hypotensive or haemodynamically unstable states.
• with aliskiren-containing medicines in patients with diabetes or with moderate to severe renal impairment (creatinine clearance <60 ml/min).
• with angiotensin II receptor antagonists (AIIRAs) in patients with diabetic nephropathy.
• during pregnancy.

Concomitant use of ACE inhibitors and extracorporeal treatments leading to contact of blood with negatively charged surfaces must be avoided, since such use may lead to severe anaphylactoid reactions. Such extracorporeal treatments include dialysis or haemofiltration with certain high-fux (e.g. polyacrylonitril) membranes and low-density lipoprotein apheresis with dextran sulfate.

Ramipril should be used with caution in patients with impaired renal function, hyperkalaemia, hypotension, and impaired hepatic function.

Concomitant administration with diuretics may lead to serious hypotension and in addition dangerous hyperkalemia with potassium sparing diuretics. Concomitant therapy with lithium may increase the serum lithium concentration. Reduction in BP may affect the ability to drive and operate machinery and this may be exacerbated by alcohol. NSAIDs may reduce the antihypertensive effect of Ramipril and cause deterioration of renal function.

Ramipril must not be taken during pregnancy. Therefore, pregnancy must be excluded before starting treatment. Pregnancy must be avoided in cases where treatment with ACE inhibitors is indispensable. If the patient intends to become pregnant, treatment with ACE inhibitors must be discontinued, i.e. replaced by another form of treatment. If the patient becomes pregnant during treatment, medication with Ramipril must be replaced as soon as possible by a treatment regimen without ACE inhibitors. Otherwise, there is a risk of harm to the fetus. Ramipril is not recommended during breastfeeding.

Elderly: A reduced initial dose of 1.25 mg Ramipril daily must be considered.

Hepatic impairment: Treatment in these patients must therefore be initiated only under close medical supervision. The maximum permitted daily dose in such cases is 2.5 mg Ramipril.

Renal impairment: With a creatinine clearance between 50 and 20 ml/min per 1.73 m2 body surface area, the initial daily dose is generally 1.25 mg Ramipril. The maximum permitted daily dose, in this case, is 5 mg Ramipril. Patients with incompletely corrected fuid or salt depletion, in patients with severe hypertension, as well as in patients in whom a hypotensive reaction would constitute a particular risk, (e.g., with relevant stenoses of the coronary vessels or those supplying the brain) A reduced initial dose of 1.25 mg Ramipril daily must be considered.

Patients pretreated with a diuretic: Consideration must be given to discontinuing the diuretic for at least 2 to 3 days or- depending on the duration of action of the diuretic- longer before starting treatment with Ramipril, or at least to reducing the diuretic dose. The initial daily dose in patients previously treated with a diuretic is generally 1.25 mg Ramipril.

Sign and symptom: Overdosage may cause excessive peripheral vasodilatation (with marked hypotension, shock), bradycardia, electrolyte disturbances, and renal failure.

Management: Primary detoxifcation by, for example, gastric lavage, administration of adsorbents, sodium sulfate; (if possible during the frst 30 minutes). In the event of hypotension administration of α1-adrenergic agonists (e.g. norepinephrine, dopamine) or angiotensin II (angiotensinamide), which is usually available only in scattered research laboratories, must be considered in addition to volume and salt substitution.

Store at 30° or below, protect from light. Keep out of the reach of children. Do not use later than the date of expiry. To be dispensed only on the prescription of a registered physician.

Indicated for the treatment of mild to moderate hypertension in patients (in whom combination therapy is appropriate) who have been stabilised on the individual components given in the same proportion.

Combined antihypertensive preparations

Ramipril is an angiotensin converting enzyme (ACE) inhibitor, which after hydrolysis to ramiprilat, blocks the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. So, inhibition of ACE by ramipril results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and decreased aldosterone secretion. Thus ramipril exerts its antihypertensive activity. It is also effective in the management of heart failure and reduction of the risk of stroke, myocardial infarction and death from cardiovascular events. It is long acting and well tolerated; so, can be used in long term therapy.

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 anangiotensin converting enzyme (ACE) inhibitor tends to reverse the potassium loss associated with these diuretics.

Dose Titration Guided by Clinical Effect. A patient whose blood pressure is not adequately controlled with ramipril (or another ACE inhibitor) alone or with hydrochlorothiazide (or another thiazide diuretic) alone may be switched to combination therapy with Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or Ramipril 5 mg + Hydrochlorothiazide 25 mg tablet.

Replacement Therapy: For convenience, patients receiving ramipril and hydrochlorothiazide from separate tablets may instead wish to receive tablets of combination of Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or Ramipril 5 mg + Hydrochlorothiazide 25 mg. If necessary, the dose may be increased to two tablets of Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or Ramipril 5 mg + Hydrochlorothiazide 25 mg once daily.

Maximum daily dose: 10 mg ramipril and 50 mg hydrochlorothiazide (four tablets of Ramipril 2.5 mg + Hydrochlorothiazide 12.5 mg or two tablets of Ramipril 5 mg + Hydrochlorothiazide 25 mg).

The combination of Ramipril and Hydrochlorothiazide is generally well tolerated. Side effects commonly reported include headache, dizziness, asthenia, nausea, vomiting, hypotension, cough, weakness, diarrhoea, fever, gastric irritation, pulmonary oedema, photosensitivity, electrolyte imbalance, hyperglycaemia, hyperuricaemia and vertigo.

This preparation must not be used in patients with hypersensitivity to ramipril, hydrochlorothiazide or other thiazide diuretics. History of hereditary angioneurotic oedema. Severe impairment of renal function. Haemodynamically relevant unilateral or bilateral renal artery stenosis, mitral stenosis, aortic stenosis, and in patients with low blood pressure (hypotensive patients) or in patients with an unstable circulatory situation (haemodynamically unstable patients) where there might be a risk of life-threatening fall in blood pressure and renal failure. Clinically relevant electrolyte disturbances e.g. hypokalemia, hyponatremia or hypercalcemia which may worsen following treatment.

Treatment with Ramipril and Hydrochlorothiazide combination requires regular medical supervision. Generally dehydration, reduced blood volume (hypovolumia) or salt depletion should be corrected before initiating the treatment (in patients with concomitant heart failure, however, this must be carefully weighed against the risk of volume overload).

Special caution is necessary during the treatment of: Patients with severe and particularly with malignant hypertension. Patients with concomitant and particularly with severe heart failure. Patients in whom fluid or salt deficiency exists or may develop (as a result of inadequate fluid or salt intake) or as a result of diarrhoea, vomiting or excessive sweating in cases where salt and fluid replacement is inadequate. Patients with haemodynamically relevant renal artery stenosis. In patients with pre-existing impairment of renal function or in kidney transplant patients. White blood cell count should be monitored (more frequent in the initial phase of the treatment) so that leucopenia can be detected. Insufficient experience has been gained concerning the use of Ramipril and Hydrochlorothiazide combination in children.

Combination with diuretics or other antihypertensive agents or nitrates and tricyclic antidepressants may potentiate the antihypertensive response to Ramipril and Hydrochlorothiazide combination. Patients previously treated with diuretics may experience a marked drop in blood pressure. Ramipril / Hydrochlorothiazide may weaken the effectiveness of blood sugar lowering medications (antidiabetic agents, e.g. insulin and sulphonylurea derivatives). When Ramipril/Hydrochlorothiazide is administered simultaneously with acetyl salicylic acid or indomethacin, attenuation of antihypertensive effect and moreover acute renal failure may occur. Ramipril / Hydrochlorothiazide may potentiate the effects of alcohol.

ACE inhibitors can cause foetal and neonatal morbidity and death when administered to pregnant women. Also, thiazides cross the placental barrier and appear in cord blood. There is a risk of foetal or neonatal jaundice, thrombocytopenia, and possibly other adverse reactions that have occurred in adults. When pregnancy is detected, Ramipril and Hydrochlorothiazide combination should be discontinued as soon as possible. This product is excreted in breast milk. Because of the potential for serious adverse reactions in nursing infants, women receiving Ramipril and Hydrochlorothiazide combination should not breast feed.

Dosage in renal impairment: In patients with a creatinine clearance between 60 and 30 ml/min, treatment should be initiated with Ramipril 1.25 mg monotherapy. If blood pressure is not adequately controlled, the dose of Ramipril may be increased to 2.5 mg. If blood pressure is still not controlled, patient may be switched to one tablet of Ramoril 2.5 Plus once daily. Dosage may be titrated upward to Ramoril 5 Plus until blood pressure is controlled.

Uue in children: Safety and effectiveness in paediatric patients have not been established

Ramipril: Limited data on human overdosage are available. The most likely clinical manifestations would be symptoms attributable to hypotension. Because the hypotensive effect of Ramipril is achieved through vasodilation and effective hypovolemia, it is reasonable to treat Ramipril overdosage by infusion of normal saline solution.

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.

Clobetasol Propionate is indicated for adults, elderly and children over 1 year in following dermatoses.

• Psoriasis (excluding widespread plaque psoriasis)
• Recalcitrant dermatoses
• Lichen planus
• Discoid lupus erythematosus
• Other skin conditions which do not respond satisfactorily to less potent steroids

Other Topical corticosteroids

Clobetasol Propionate is a very potent topical corticosteroid. It has anti-inflammatory, antipruritic and vasoconstrictive properties. It shows anti-inflammatory activity via multiple mechanisms to inhibit late phase allergic reactions. It decreases the density of mast cells, chemotaxis and activation of eosinophils. It also reduces cytokine production and inhibits the metabolism of arachidonic acid.

Adults, elderly and children over 1 year: Apply a thin layer of Clobetasol Propionate Cream or Ointment to the affected skin areas twice daily and rub in gently and completely. Repeated short courses of Clobetasol Propionate may be used to control exacerbations. In more resistant lesions, especially where there is hyperkeratosis, the effect of Clobetasol can be enhanced, if necessary, by occluding the treatment area with polythene film. Overnight occlusion only is usually adequate to bring about a satisfactory response. Clobetasol Propionate is super-high potency topical corticosteroids; therefore, treatment should be limited to 2 consecutive weeks. The maximum weekly dose should not be exceeded 50 gm/week. In case of children, courses should be limited if possible to five days and reviewed weekly.

Route of administration: Cutaneous. Creams are especially appropriate for moist or weeping surfaces. Ointments are especially appropriate for dry, lichenified or scaly lesions.

The most reported side effects are burning and stinging sensation. Less frequent adverse reactions are itching, skin atrophy, cracking and fissuring of the skin. Cushing syndrome has been reported in infants and adults as a result of prolonged use of topical Clobetasol Propionate formulations.

It is contraindicated in patient with hypersensitivity to any component of the preparation. It should not be used in rosacea, acne vulgaris, perioral dermatitis, perianal and genital pruritus, pruritus without inflammation, untreated cutaneous infections.

In case of using occlusive dressings, the skin should be cleansed before a fresh dressing is applied. Topical corticosteroids should be used with caution in psoriasis as rebound relapses, and development of local or systemic toxicity due to impaired barrier function of the skin may occur. If used on the face, treatment should be limited to 5 days. When Clobetasol Propionate used on eyelids, care should be taken to avoid the eyes as cataract and glaucoma might result from repeated exposure.

Co-administered drugs that can inhibit CYP3A4 (eg ritonavir, itraconazole) have been shown to inhibit the metabolism of corticosteroids leading to increased systemic exposure.

There are limited data from the use of Clobetasol Propionate cream in pregnant women. Topical administration of corticosteroids to pregnant animals can cause abnormalities of foetal development. The relevance of this finding to humans has not been established. However, the administration of Clobetasol Propionate Cream during pregnancy and lactation should only be considered if the expected benefit to the mother outweighs the possible risks of treatment.

It is unknown whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Clobetasol Propionate Cream is administered to a nursing woman.

In infants and children under 12 years of age, long-term continuous topical corticosteroid therapy should be avoided where possible, as adrenal suppression can occur. Children are more susceptible to the use of topical corticosteroids which develops atrophic changes.

Acute overdosage is very unlikely to occur, however, in the case of chronic over-dosage or misuse the features of hypercortisolism may occur and in this situation topical steroid should be discontinued.

Keep below 30°C temperature, protected from light and moisture. Do not freeze. Keep out of the reach of children.
