Antiparkinson drugs

If 100/10 mg tablet is used: Dosage may be initiated with one tablet three or four times a day. Titration upward may be required in some patients to achieve optimum dosage of carbidopa. The dosage may be increased by one tablet every day or every other day until a total of eight tablets (two tablets q.d.s.) is reached.

For patients starting with 250/25 mg tablet: The initial dose is one half taken once or twice daily. However, this may not provide the optimal amount of Carbidopa needed by many patients. If necessary, add one-half every day or every other day until optimal response is reached. The suggested starting dosage for most patients taking more than 1500 mg of Levodopa a day is one tablet of 250/25 mg three or four times a day.

Maintenance dose: Therapy should be individualized and adjusted according to the desired therapeutic response. When more levodopa is requried, 250/25 mg tablet should be substituted at a dosage of one tablet three or four times a day. If necessary, the dosage of 250/25 mg tablet may be increased by half to one tablet every other day to a maximum of eight tablets a day. Experience with a total daily dosage greater than 200 mg Carbidopa is limited.

Adverse effects that occur frequently in patients receiving Carbidopa-Levodopa are those due to the central neuropharmacologic activity of dopamine. These reactions usually can be diminished by dosage reduction. The most common adverse effects are dyskinesias including choreiform, dystonic, and other involuntary movements and nausea.

• Body as a whole: syncope, chest pain, anorexia.
• Cardiovascular: palpitation, orthostatic effects including hypotensive episodes, hypertension, phlebitis.
• Gastrointestinal: vomiting, gastrointestinal bleeding, development of duodenal ulcer, diarrhoea, dark saliva.
• Haemotologic: leukopenia, haemolytic and non-haemolytic anaemia, thrombocytopenia, agranulocytosis.
• Hypersensitivity: angioedema, urticaria, pruritus, Henoch-Schonlein purpura.
• Nervous System: dizziness, somnolence, paresthesia, delusions, hallucinations and paranoid ideation, depression with or without development of suicidal tendencies, dementia, dream abnormalities, agitation, confusion, increased libido.
• Respiratory: dyspnea.
• Skin: alopecia, rash, dark sweat.
• Urogenital: dark urine.

Carbidopa-Levodopa tablet is contraindicated in patients with hypersensitivity to Carbidopa and Levodopa, and in patients with narrow-angle glaucoma. Since Levodopa may activate a malignant melanoma, Carbidopa-Levodopa should not be used in patients with suspicious undiagnosed skin lesions or a history of melanoma.

Carbidopa-Levodopa is not recommended for the treatment of medicine-induced extrapyramidal reactions. Carbidopa Levodopa may be given to patients already taking Levodopa alone; however, the Levodopa must be discontinued at least 12 hours before Carbidopa-Levodopa started. Dyskinesias may occur in patients previously treated with Levodopa alone because Carbidopa permits more Levodopa to reach the brain and, thus, more dopamine to be formed. The occurrence of dyskinesias may require dosage reduction. All patients should be observed carefully for the development of depression with concomitant suicidal tendencies. Patients with past or current psychoses should be treated with caution. Carbidopa-Levodopa should be administered cautiously to patients with severe cardiovascular or pulmonary disease, bronchial asthma, renal, hepatic or endocrine disease, or a history of peptic ulcer disease or of convulsions.

Care should be exercised to patients with a history of myocardial infarction who have atriai, nodal, or ventricular arrhythmia. In such patients, cardiac function should be monitored with particular care during the period of initial dosage administration and titration. Patients with chronic wide-angle glaucoma may be treated cautiously with Carbidopa-Levodopa, provided the intraocular pressure is weli controlled and the patient monitored carefully for changes in intraocular pressure during therapy.

Symptomatic postural hypotension has occurred when Carbidopa-Levodopa is added to the treatment of a patient receiving antihypertensive medicines. Therefore, when therapy with CarbidopaLevodopa is started, dosage adjustment of the antihypertensive medicine may be required. There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and Carbidopa-Levodopa. Studies demonstrate a decrease in the bioavailability of Carbidopa and/or Levodopa when it is ingested with ferrous sulphate or ferrous gluconate. Dopamine-2 receptor antagonists (e.g., phenothiazines, butyrophenones and risperidone) and isoniazid may reduce the therapeutic effects of Levodopa. In addition, the beneficial effects of Levodopa in Parkinson's disease have been reported to be reversed by phenytoin and papaverine. Patients taking these medicines with Carbidopa-Levodopa should be carefully observed for loss of therapeutic response. Concomitant therapy with selegiline and Carbidopa-Levodopa may be associated with severe orthostatic hypotension not attributable to Carbidopa-Levodopa alone.

Although the effects of CarbidopaLevodopa on human pregnancy are unknown both Levodopa and combinations of Carbidopa and Levodopa have caused visceral and skeletal malformations in rabbits. Therefore, use of CarbidopaLevodopa in women of childbearing potential requires that the anticipated benefits of the medicine be weighed against possible hazards should pregnancy occur. It is not known whether Carbidopa is excreted in human milk. Because many medicines are excreted in human milk and because of the potential for serious adverse reactions in infants, a decision should be made whether to discontinue nursing or to discontinue the use of Carbidopa-Levodopa, taking into account the importance of the medicine to the mother.

Use in children: Safety and effectiveness of Carbidopa-Levodopa in infants and children have not been established, and its use in patients below the age of 18 years is not recommended.

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

Epalrestat consequently improves peripheral neuropathy due to sorbitol accumulation. It is usually used to improve numbness, pain and abnormality of vibration sensation/heart rate variability associated with diabetic peripheral neuropathy.

Aldose reductase inhibitor

Epalrestat is aldose reductase inhibitor. The aldose reductase inhibitors have a distinct mechanism of action, affecting the underlying disease process in diabetic neuropathy, although the extent of the polyol pathway involvement is yet to be determined. This medicine suppresses accumulation of sorbitol in cells by inhibiting action of aldose reductase which converts glucose of sugar to sorbitol. Epalrestat may improve motor and sensory nerve conduction velocity and subjective neuropathy symptoms.

In general, for adults, take 1 tablet (50 mg of the active ingredient) at a time, 3 times a day before meals. The dosage may be adjusted according to your age and symptoms.

The most commonly reported adverse reactions include abdominal pain, nausea, rash, itch, erythema and blister.

Your urinary color may turn yellowish brown or red due to color of the component of this medicine. Do not worry about the change.

Albendazole is indicated in single and mixed infestations of-

• Hookworm (Ancylostoma, Necator)
• Roundworm (Ascaris)
• Threadworm (Enterobius)
• Whipworm (Trichuris)
• Strongyloides
• Tapeworm
• Opisthorchi
• Hydatid.

Anthelmintic

Albendazole is a broad spectrum anthelmintic. Albendazole exhibits vermicidal, ovicidal and larvicidal activities. The drug is thought to exert its anthelmintic effect by blocking glucose uptake in the susceptible helminths, thereby depleting the energy level until it becomes inadequate for survival. Immobilization is followed by the parasite. These events may be a consequence of the binding and subsequent inhibition of parasite tubulin polymerization by Albendazole and its metabolites, although the drug also binds to human tubulin. Albendazole is extensively metabolized, probably in the liver. Albendazole is poorly absorbed from the gastrointestinal tract but rapidly undergoes extensive first-pass metabolism. The principal metabolite albendazole sulphoxide has anthelmintic activity and a plasma half-life of about 8.5 hrs. It is excreted in the urine together with other metabolites.

Adults & children over 2 years:

• 400 mg (1 tablet or 10 ml suspension) as a single dose in cases of Enterobius vermicularis, Trichuris trichiura, Ascaris lumbricoides, Ancylostoma duodenale and Necator americanus.
• In cases of strongyloidiasis or taeniasis, 400 mg (1 tablet or 10 ml suspension) daily should be given for 3 consecutive days. If the patient is not cured on follow-up after three weeks, a second course of treatment is indicated. 

Children of 1-2 years: Recommended dose is a single dose of 200 mg (5 ml suspension).

Children under 1 year: Not recommended.

In Hydatid disease (Echinococcosis):

• Albendazole is given by mouth with meals in a dose of 400 mg twice daily for 28 days for patients weighing over 60 kg.
• A dose of 15 mg/kg body weight daily in two divided doses (to a maximum total daily dose of 800 mg) is used for patients weighing less than 60 kg.
• For cystic echinococcosis, the 28 days course may be repeated after 14 days without treatment, to a total of 3 treatment cycles.
• For alveolar echinococcosis, cycles of 28 days of treatment followed by 14 days without treatment, may need to continue for months or years.
• In giardiasis, 400 mg (1 tablet or 10 ml suspension) once daily for five days is used.

Gastrointestinal disturbances, headache, dizziness, changes in liver enzymes, rarely reversible alopecia; rash, fever, blood disorders including leucopenia and pancytopenia reported; allergic shock if cyst leakage; convulsion and meningism in cerebral disease.

Neonates: Albendazole is not normally used in neonates.

Children: Reduction of the dose from 400 mg to 200 mg may be indicated in children weighing less than 10 kg but there are no grounds for a general reduction in dosage to children.

Pregnant woman: Albendazole should not be given during pregnancy or women thought to be pregnant. No information is available on placental transfer.

Concurrent disease: There is no evidence to suggest that dose should be altered in renal, hepatic or cardiac failure.

Blood counts and liver function tests before treatment and twice during each cycle; breastfeeding; exclude pregnancy before starting treatment. Albendazole should only be used in the treatment of Echinococcosis if there is constant medical supervision with regular monitoring of serum-transaminase concentrations and of leucocyte and platelet counts

No interaction involving Albendazole, either pharmacodynamic or pharmacokinetic, has been reported.

US FDA Pregnancy category of Albendazole is C. So, Albendazole should be avoided in pregnancy and lactation unless the potential benefits to the other outweigh the possible risks to the fetus.

Keep in a dry place, away from light and heat. Keep out of the reach of children.

Alectinib indicated for the treatment of patients with anaplastic lymphoma kinase (ALK)-positive, locally advanced or metastatic non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to crizotinib.

Anti neoplastic preparations, Protein kinase inhibitor

Alectinib is a highly selective and potent ALK and RET tyrosine kinase inhibitor.In nonclinicalstudies, inhibition of ALK tyrosine kinase activity led to blockage of downstream signaling pathways including STAT 3 and PI3K/AKT and inducedtumor cell death (apoptosis).

Alectinib demonstratedin vitroand in vivoactivity against mutant forms of the ALK enzyme, including mutations responsible forresistance to crizotinib.The major metabolite of alectinib (M4) has shown similar in vitropotency and activity.

Based on nonclinicaldata, alectinib is not a substrate of p-glycoprotein (P-gp) or breast cancer resistance protein (BCRP), which are both efflux transporters in the blood brain barrier, and is therefore able to distribute into and be retained within the central nervous system. Alectinibinducedtumor regressionin nonclinicalmousexenograft models, including antitumor activity in the brain, and prolonged survival inintracranial tumor animal models.

The recommended dose of Alectinib is 600 mg (four 150 mg capsules) given orally, twice daily (total daily dose of 1200 mg). Patients with underlying severe hepatic impairment should receive a dose of 450 mg given orally twice daily (total daily dose of 900 mg). Alectinib hard capsules should be taken with food, swallowed whole and must not be opened or dissolved.

Duration of Treatment: It is recommended that patients are treated with Alectinib until disease progression or unmanageable toxicity.

Dose Modifications: Management of adverse events may require temporary interruption, dosereduction, or discontinuation of treatment with Alectinib. The dose of Alectinib should be reduced in steps of 150 mg twice daily based on tolerability. Alectinib treatment should be permanently discontinued if patients are unable to tolerate the 300 mg twice-daily dose.

The most common adverse drug reactions were constipation, edema including peripheral, generalized, eyelid, periorbital; myalgia (31% including myalgia and musculoskeletal pain), nausea, increased bilirubin (21% including increased blood bilirubin, hyperbilirubinemia and increased bilirubin conjugated), anemia (20%, including anemia and hemoglobin decreased), and rash (20%, including rash, rash maculopapular, dermatitis acneiform, erythema, rash generalized, rash papular, rash pruritic and rash macular).

Alectinib is contraindicated in patients with a known hypersensitivity to alectinib or any of the excipients.

Interstitial lung disease (ILD)/pneumonitis: Cases of ILD/pneumonitishave been reported in clinical trials with Alectinib. Patients should be monitored for pulmonary symptoms indicative of pneumonitis. Alectinib should be immediately interrupted in patients diagnosed with ILD/pneumonitis and should be permanently discontinued if no other potential causes of ILD/pneumonitis have been identified

Hepatotoxicity: Elevations in alanine amino transferase (ALT) and aspartate amino transferase (AST) greater than 5 times the upper limit of normal (ULN) as well as bilirubin elevations of more than 3 times the ULN occurred in patients in pivotal clinical trials with Alectinib. The majority of these events occurred during the first 3months of treatment. In the pivotal Alectinib clinical trials it was reported that three patients with Grade 3‒4 AST/ALT elevations had drug-induced liver injury. Concurrent elevations in ALT or AST greater than or equal to three times the ULN and total bilirubin greater than or equal to two times the ULN, with normal alkaline phosphatase, occurred in 1 patient treated in Alectinib clinical trials.

In vitro studies indicate that neither alectinib nor its major active metabolite (M4) inhibits CYP1A2, CYP2B6, CYP2C9, CYP2C19, or CYP2D6 at clinically relevant concentrations. Alectinib and M4 show weak time-dependent inhibition of CYP3A4. In vitro, alectinib exhibits a weak induction potential of CYP3A4 and CYP2B6 at clinical concentrations. Results from a clinical drug-drug interaction study in ALK-positive NSCLC patients demonstrated that multiple doses of alectinib had no influence on the exposure of midazolam, a sensitive CYP3A substrate. Therefore, no dose adjustment is required for co-administered CYP3A substrates. Although in vitro studies indicate that alectinib is an inhibitor of CYP2C8, physiologically based pharmacokinetic (PBPK) modeling supports that at clinically relevant concentrations alectinib does not have the potential to increase plasma concentrations of co-administered substrates of CYP2C8.

Pregnancy: Women of childbearing potential must be advised to avoid pregnancy while on Alectinib. No clinical studies of Alectinib in pregnant women have been performed. Based on its mechanism of action, Alectinib may cause fetal harm when administered to a pregnant woman. Female patients or women who are partners of male patients receiving Alectinib, who become pregnant while taking Alectinib or during the 3 months following the last dose of Alectinib must contact their doctor and should be advised of the potential harm to the fetus.

Lactation: It is not known whether Alectinib is excreted in human breast milk. No studies have been conducted to assess the impact of Alectinib on milk production or its presence in breast milk. As many drugs are excreted in human milk and because of the potential harm to the infant, mothers should be advised against breastfeeding while receiving Alectinib.

Contraception: Female patients of child-bearing potential, or women of child-bearing potential who are partners of male patients receiving Alectinib, must use highly effective contraceptive methods during treatment and for at least 3 months following the last dose of Alectinib

Pediatric use: The safety and efficacy of alectinib in children and adolescents (<18 years) have not been studied.

Geriatric use: No dose adjustment of alectinib is required in patients≥65 years of age.

Renal impairment: No dose adjustment is required in patients with mild or moderate renal impairment. alectinib has not been studied in patients with severe renal impairment, however,since alectinib elimination via the kidney is negligible, no dose adjustment is required inpatients with severe renal impairment

Hepatic impairment: No dose adjustment is required in patients with underlying mild or moderate hepatic impairment. Patients with underlying severe hepatic impairment should receive a dose of 450 mg given orally twice daily (total daily dose of 900 mg)

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

Bisphosphonate preparations

Alendronate is a bisphosphonate that binds to bone hydroxyapatite and specifically inhibits the activity of osteoclasts, the bone-resorbing cells. Alendronate reduces bone resorption with no direct effect on bone formation, although the latter process is ultimately reduced because bone resorption and formation are coupled during bone turnover.

Animal studies have indicated the following mode of action. At the cellular level, alendronate shows preferential localization to sites of bone resorption, specifically under osteoclasts. The osteoclasts adhere normally to the bone surface but lack the ruffled border that is indicative of active resorption. Alendronate does not interfere with osteoclast recruitment or attachment, but it does inhibit osteoclast activity. Studies in mice on the localization of radioactive [3H] alendronate in bone showed about 10-fold higher uptake on osteoclast surfaces than on osteoblast surfaces. Bones examined 6 and 49 days after [3H] alendronate administration in rats and mice, respectively, showed that normal bone was formed on top of the alendronate, which was incorporated inside the matrix. While incorporated in bone matrix, alendronate is not pharmacologically active. Thus, alendronate must be continuously administered to suppress osteoclasts on newly formed resorption surfaces. Histomorphometry in baboons and rats showed that alendronate treatment reduces bone turnover (i.e., the number of sites at which bone is remodeled). In addition, bone formation exceeds bone resorption at these remodeling sites, leading to progressive gains in bone mass.

Treatment of Osteoporosis in Postmenopausal Women: The recommended dosage is one 70 mg tablet once weekly or one bottle of 70 mg oral solution once weekly or one 10 mg tablet once daily.

Prevention of Osteoporosis in Postmenopausal Women: The recommended dosage is one 35 mg tablet once weekly or one 5 mg tablet once daily.

Treatment to Increase Bone Mass in Men with Osteoporosis: The recommended dosage is one 70 mg tablet once weekly or one bottle of 70 mg oral solution once weekly or one 10 mg tablet once daily.

Treatment of Glucocorticoid-Induced Osteoporosis: The recommended dosage is one 5 mg tablet once daily, except for postmenopausal women not receiving estrogen, for whom the recommended dosage is one 10 mg tablet once daily.

Treatment of Paget's Disease of Bone: The recommended treatment regimen is 40 mg once a day for six months.

The commonest symptomatic side effects are constipation, diarrhoea, oesophageal ulcer, flatulence, dysphagia, musculoskeletal pain, headache, rarely rash, erythema, transient decrease in serum calcium and phosphate, nausea, vomiting, peptic ulceration, hypersensitivity reactions including urticaria and angio-oedema.

Alendronic acid is contraindicated in patients with the following conditions: 

• Abnormalities of the esophagus which delay esophageal emptying such as stricture or achalasia.
• Inability to stand or sit upright for at least 30 minutes.
• Do not administer Alendronic acid oral solution to patients at increased risk of aspiration.
• Hypocalcemia.
• Hypersensitivity to any component of this product. Hypersensitivity reactions including urticaria and angioedema have been reported.

The incidence of upper gastrointestinal side effects are increased with the concomitant use of non-steroidal anti-inflammatory agents and aspirin. Absorption of Alendronate is reduced in the presence of antacids and calcium supplements.

Alendronic acid should not be given to pregnant women or nursing mother.

Pediatric Use: Alendronic acid is not indicated for use in pediatric patients.

Renal Impairment: Alendronic acid is not recommended for patients with creatinine clearance less than 35 mL/min. No dosage adjustment is necessary in patients with creatinine clearance values between 35-60 mL/min.

Hepatic Impairment: As there is evidence that alendronate is not metabolized or excreted in the bile, no studies were conducted in patients with hepatic impairment. No dosage adjustment is necessary.

Tenofovir Alafenamide is a hepatitis B virus (HBV) nucleoside analog reverse transcriptase inhibitor and is indicated for the treatment of chronic hepatitis B virus infection in adults with compensated liver disease.

Hepatic viral infections (Hepatitis B)

Tenofovir alafenamide is a phosphonamidate prodrug of tenofovir (2'-deoxyadenosine monophosphate analog). Tenofovir alafenamide as a lipophilic cell-permeant compound enters primary hepatocytes by passive diffusion and by the hepatic uptake transporters OATP1B1 and OATP1B3. Tenofovir alafenamide is then converted to tenofovir through hydrolysis primarily by carboxylesterase 1 (CES1) in primary hepatocytes. Intracellular tenofovir is subsequently phosphorylated by cellular kinases to the pharmacologically active metabolite tenofovir diphosphate. Tenofovir diphosphate inhibits HBV replication through incorporation into viral DNA by the HBV reverse transcriptase, which results in DNA chain-termination.

Tenofovir diphosphate is a weak inhibitor of mammalian DNA polymerases that include mitochondrial DNA polymerase γ and there is no evidence of toxicity to mitochondria in cell culture.

Testing Prior To Initiation Of Tenofovir Alafenamide: Prior to initiation of Tenofovir Alafenamide, patients should be tested for HIV-1 infection. Tenofovir Alafenamide alone should not be used in patients with HIV infection

It is recommended that serum creatinine, serum phosphorous, estimated creatinine clearance, urine glucose, and urine protein be assessed before initiating Tenofovir Alafenamide and during therapy in all patients as clinically appropriate

Recommended Dosage In Adults: The recommended dosage of Tenofovir Alafenamide is 25 mg (one tablet) taken orally once daily with food

The following adverse reactions are discussed in other sections of the labeling:

• Lactic Acidosis/Severe Hepatomegaly with Steatosis 
• Severe Acute Exacerbation of Hepatitis B
• New Onset or Worsening of Renal Impairment

The most common side effects are headache, stomach pain, tiredness, cough, nausea, back pain

None

Tenofovir is a substrate of P-glycoprotein (P-gp) and BCRP. Drugs that strongly affect P-gp and BCRP activity may lead to changes in Tenofovir absorption. Consult the full prescribing information prior to and during treatment for potential drug drug interactions.

Before you take Tenofovir Alafenamide, tell your healthcare provider about all of your medical conditions, including if you are pregnant or plan to become pregnant. It is not known if Tenofovir Alafenamide will harm your unborn baby. Tell your healthcare provider if you become pregnant during treatment with Tenofovir Alafenamide. 

Pregnancy Registry: There is a pregnancy registry for women who take antiviral medicines during pregnancy. The purpose of this registry is to collect information about the health of you and your baby. Talk with your healthcare provider about how you can take part in this registry.

Pediatric Use: Safety and effectiveness of Tenofovir Alafenamide in pediatric patients less than 18 years of age have not been established.

Geriatric Use: Clinical trials of Tenofovir Alafenamide did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Renal Impairment: No dosage adjustment of Tenofovir Alafenamide is required in patients with mild, moderate, or severe renal impairment. Tenofovir Alafenamide is not recommended in patients with end stage renal disease (estimated creatinine clearance below 15 mL per minute) 

Hepatic Impairment: No dosage adjustment of Tenofovir Alafenamide is required in patients with mild hepatic impairment (Child-Pugh A). The safety and efficacy of Tenofovir Alafenamide in patients with decompensated cirrhosis (Child-Pugh B or C) have not been established; therefore Tenofovir Alafenamide is not recommended in patients with decompensated (Child-Pugh B or C) hepatic impairment

If overdose occurs, monitor patient for evidence of toxicity. Treatment of overdosage with Tenofovir Alafenamide consists of general supportive measures including monitoring of vital signs as well as observation of the clinical status of the patient. Tenofovir is efficiently removed by hemodialysiswith an extraction coefficient of approximately 54%

Store below 86°F (30°C). Keep in its original container. Keep the container tightly closed.

Olopatadine Nasal Spray is an H1 receptor antagonist indicated for the relief of the symptoms of seasonal allergic rhinitis in adults and children 6 years of age and older.

Nasal Anti-histamine preparations

Olopatadine, an antihistamine, works by blocking the action of histamine in the body, which reduces allergy symptoms. Olopatadine Hydrochloride treats sneezing, itching, runny nose, and other nasal symptoms of allergies. Olopatadine Nasal Spray contains 0.6% w/v Olopatadine (base) in a nonsterile aqueous solution with pH of approximately 3.7. After initial priming (5 sprays), each metered spray from the nasal applicator delivers 100 microliters of the aqueous solution containing 665 mcg of olopatadine Hydrochloride, which is equivalent to 600 mcg of Olopatadine (base). Olopatadine Nasal Spray also contains benzalkonium chloride (0.01%), dibasic sodium phosphate, edetate disodium, sodium chloride, hydrochloric acid and/or sodium hydroxide (to adjust pH), and purified water.

Adults and Adolescents 12 years of age and older: Two sprays per nostril twice daily.

Children 6 to 11 years of age: One spray per nostril twice daily.

Administer Olopatadine Nasal Spray by the intranasal route only.

How to use the Nasal Spray-

• Shake the bottle gently and remove the dust cover.
• Hold the spray with your forefinger and middle finger on either side of the nozzle and your thumb underneath the bottle. Press down until a fine spray appears. If using for the first time or if you have not used it for a week or more, press the nasal applicator several times until a fine moist comes out from the container.
• Gently blow the nose to clear the nostrils.
• Close one nostril and carefully insert the nasal applicator into the open nostril. Tilt your head forward slightly and keep the spray upright. Breathe in through your nose and while breathing in, press the white-collar of nasal applicator firmly down once to release a spray.
• Breathe out through your mouth.
• Repeat the above steps in the same/ other nostril for consecutive doses.

Cleaning: The nasal spray should be cleaned at least once a week. The procedures are as follows-

• Remove the dust cover.
• Gently pull off the nasal applicator.
• Wash the applicator and dust cover in warm water.
• Shake off the excess water and leave to dry in a normal place. Avoid to apply additional heat.
• Gently push the applicator back on the top of the bottle and re-fix the dust cover.

A bitter taste in the mouth, nosebleeds, or irritation/soreness in the nose may occur. Drowsiness may rarely occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Before initial use, Olopatadine Nasal Spray by releasing 5 sprays or until a fine mist appears. When Olopatadine Nasal Spray has not been used for more than 7 days, re-prime by releasing 2 sprays. Avoid spraying Olopatadine Nasal Spray into the eyes. Patients should be informed to avoid spraying Olopatadine Nasal Spray in their eyes.

Interaction with other medications have not been investigated.

Pregnancy Category C. No adequate and well-controlled studies in pregnant women have been conducted. Olopatadine Nasal Spray should be used in pregnant women only if the potential benefit to the mother justifies the potential risk to the embryo or fetus.

Lactation: It is not known whether topical nasal administration could result in sufficient systemic absorption to produce detectable quantities in human breast milk. Olopatadine Nasal Spray should be used by nursing mothers only if the potential benefit to the patient outweighs the potential risks to the infant.

There have been no reported overdoses with Olopatadine Nasal Spray.

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

Olopatadine is indicated for the treatment of ocular itching associated with allergic conjunctivitis.

Ophthalmic Non-Steroid drugs

Olopatadine is an inhibitor of the release of histamine from the mast cell and a relatively selective histamine H1‐antagonist that inhibits the in vivo and in vitro type 1 immediate hypersensitivity reaction including inhibition of histamine induced effects on human conjunctival epithelial cells. Olopatadine is devoid of effects on alpha adrenergic, dopamine and muscarinic type 1 and 2 receptors. Following topical ocular administration in human, olopatadine was shown to have low systemic exposure.

0.1% Sterile Eye Drops: One drop in each affected eye two times per day at an interval of 6 to 8 hours.

0.2% Sterile Eye Drops: One drop in the affected eye once a day.

0.7% Sterile Eye Drops: One drop in each affected eye once a day.

Olopatadine Hydrochloride ophthalmic solution is contraindicated in persons with a known hypersensitivity to Olopatadine Hydrochloride.

Olopatadine HCl ophthalmic solution should not be used to treat contact lens related irritation. Patients who wear soft contact lenses should be instructed to wait at least ten minutes after instilling Olopatadine Hydrochloride ophthalmic solution before they insert their contact lenses.

May result in additive CNS depression with CNS depressants.

There are no adequate and well controlled studies in pregnant women. Because animal studies are not always predictive of human responses, this drug should be used in pregnant women only if the potential benefit to the mother justifies the potential risk to the fetus.

It is not known whether topical ocular administration could result in sufficient systemic absorption to produce detectable quantities in the human breast milk. Nevertheless, caution should be exercised when Olopatadine Hydrochloride ophthalmic solution is administered to a nursing mother.

Geriatric Use: No overall differences in safety or effectiveness have been observed betweents.

Symptoms: Drowsiness in adults and, initially, agitation and restlessness, followed by drowsiness in childn.

Management: Symptomatic or supportive treatment.

Store below 30° C in a cool and dry place protected from light. Keep out of reach of children. Do not touch the dropper tip to surfaces since this may contaminate the solution. Do not use after 30 days of first opening.

Olopatadine is indicated for the treatment of ocular itching associated with allergic conjunctivitis.

Ophthalmic Non-Steroid drugs

Olopatadine is an inhibitor of the release of histamine from the mast cell and a relatively selective histamine H1‐antagonist that inhibits the in vivo and in vitro type 1 immediate hypersensitivity reaction including inhibition of histamine induced effects on human conjunctival epithelial cells. Olopatadine is devoid of effects on alpha adrenergic, dopamine and muscarinic type 1 and 2 receptors. Following topical ocular administration in human, olopatadine was shown to have low systemic exposure.

0.1% Sterile Eye Drops: One drop in each affected eye two times per day at an interval of 6 to 8 hours.

Mizolastine is indicated for the symptomatic relief of the following conditions:

• Seasonal allergic rhinoconjunctivitis (hay fever)
• Perennial allergic rhinoconjunctivitis
• Urticaria

Non-sedating antihistamines

Mizolastine, a non-sedating antihistamine, blocks histamine H1-receptors on effector cells of the GI tract, blood vessels and respiratory tract. It also has mast-cell stabilising properties.

Adult and children above 12 years: The usual recommended dose is one 10 mg tablet daily.
Children below 12 years: Not recommended.

Mizolastine is well tolerated in the recommended doses. The usual side effects are dry mouth, diarrhoea, abdominal pain, nausea, drowsiness, headache, dizziness, raised liver enzymes, hypotension, tachycardia and palpitations. Bronchospasm and aggravation of asthma were reported, but in view of the high frequency of asthma in the treated patient population, a causality relationship remains uncertain.

Mizolastine is contra-indicated in patients with clinically significant cardiac disease or a history of symptomatic arrhythmias and in patients with known or suspected QT prolongation, patients with electrolyte imbalance (particularly hypokalaemia), and in those with clinically significant bradycardia. It is also contra-indicated in patients taking other drugs that decrease its metabolism, patients with significantly impaired liver function, and in patients who are hypersensitive to the drug.

Patients should be warned that a small number of individuals may experience sedation. It is therefore advisable to determine individual response before driving or performing complicated task.

Systemically administered Ketoconazole and Erythromycin, antiarrythmics e.g. Amiodarone moderately increase the plasma concentration of Mizolastine. This could increase the risk of arrythmias. Concurrent use of other potent inhibitor of the cytochrome P 450 3A4 enzyme e.g. Ciclosporin should be approached with caution. No potentiation of the sedation and the alteration in performance caused by alcohol with Mizolastine has been observed.

The safety of Mizolastine for use in human pregnancy has not been established. The evaluation of experimental animal studies does not indicate direct or indirect harmful effects with respect to the development of the embryo or foetus, the course of gestation and peri and post-natal development. Mizolastine should be avoided in pregnancy (particularly the 1 st trimester). Mizolastine is excreted into breast milk, therefore it is not recommended during lactation.

In cases of overdosage, general symptomatic surveillance with cardiac monitoring including QT interval and cardiac rhythm for at least 24 hours is recommended, along with standard measures to remove any unabsorbed drug. Studies in patients with renal insufficiency suggest that haemodialysis does not increase clearance of the drug.

Store in a cool & dry place. Protect from light. It should be kept out of the reach of children.

Sedating Anti-histamine

Cetirizine Hydrochloride is a potent H1 receptor antagonist without any significant anticholinergic and antiserotonic effects. At pharmacologically active dose levels, it has almost no drowsiness effect and does not cause behavioral changes. It inhibits the histamine-mediated early phase of the allergic reaction and also reduces the migration of inflammatory cells and the release of mediators associated with the late phase of the allergic reaction.

Pharmacokinetics: Cetirizine 10 mg achieves peak plasma concentrations of 257 mcg/L within one hour of administration (980 mcg/L in children). Food does not affect the extent of absorption, but it may slightly reduce the rate. Peak blood levels 0.3 micrograms/ml are reached between thirty & sixty minutes after administration of 10 mg dose of Cetirizine. Its plasma half-life is approximately 11 hours. Absorption is very consistent from one subject to the next. Its renal clearance is 30 ml/minute and the excretion half-life is approximately nine hours.

Adults and Children 6 years and older: 1 tablet or 2 teaspoonfuls daily (or 1 teaspoonful twice daily).

Children 2-6 years: 1 teaspoonful once daily or 1/2 teaspoonful twice daily.

Children 6 months to 2 years : 1/2 teaspoonful once daily. The dose in children 12-23 months of age can be increased to a maximum dose as 1/2 teaspoonful every 12 hours.

The most common side effects that occurred more frequently on Cetirizine is somnolence.

It is contraindicated in patients with a history of hypersensitivity to Cetirizine or hydroxyzine.

Caution should be exercised when driving a car or operating a heavy machinery.

No clinically significant drug interactions have been found with Theophylline, Azithromycin, Pseudoephedrine, Ketoconazole or Erythromycin and with other drugs.

US FDA Pregnancy Category of Cetirizine Hydrochloride is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
