Rifaximin is indicaed in-

• Treatment of traveler's diarrhea by noninvasive strains of E. coli
• reduction in risk of overt hepatic encephalopathy
• bacterial overgrowth of irritable bowel syndrome.

4-Quinolone preparations

Rifaximin is a semisynthetic, rifamycin-based non-systemic antibiotic. Very little of the drug will pass the gastrointestinal wall into the circulation as is common for other types of orally administered antibiotics. Rifaximin inhibits bacterial RNA synthesis by its action on the beta-subunit of the DNA-dependent RNA polymerase. It shows the same broad spectrum activity as rifamycin which exerts bactericidal action against many species of Gram-positive and Gram-negative, aerobic and anaerobic bacteria.

Traveler's Diarrhea: For patients ≥12 years of age: 200 mg 3 times daily for 3 days.
Hepatic Encephalopathy: For patients ≥18 years of age: 550 mg 2 times daily.
Bacterial overgrowth of irritable bowel syndrome: 400 mg 3 times daily for 10 days or 550 mg 3 times daily for 14 days. Can be taken with or without food

Side effects include flatulence, headache, abdominal pain, rectal tenesmus, defecation urgency, nausea, constipation, pyrexia, vomiting. Reactions have been reported, including anaphylaxis, angioneurotic edema, and exfoliative dermatitis.

Contraindicated in patients with a hypersensitivity to Rifaximin or to any of the rifamycin antimicrobial agents, or any components of this product

Rifaximin is not found to be effective in patients with diarrhea complicated by fever and/or blood in the stools. Rifaximin therapy should be discontinued if diarrhea symptoms get worse or persist for more than 24-48 hours and alternative antibiotic therapy should be considered. Pseudomembranous colitis has been reported with nearly all antibacterial agents and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.

In an in vitro study has suggested that Rifaximin induces CYP3A4. However, in patients with normal liver function, Rifaximin at the recommended dosing regimen is not expected to induce CYP3A4.

Pregnancy category C. It is not known whether Rifaximin is excreted in human milk or not.

Renal Impairment: The pharmacokinetics of Rifaximin in patients with impaired renal function has not been studied.
Hepatic Impairment: The systemic exposure of Rifaximin was markedly elevated in patients with hepatic impairment compared to healthy subjects.

No specific information is available on the treatment of over dosage with Rifaximin. In case of over dosage, discontinue Rifaximin, treat symptomatically and institute supportive measures as required.

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

Anti-Tubercular Antibiotics

Rifampicin suppresses initiation of chain formation for RNA synthesis in susceptible bacteria by binding to the β subunit of DNA-dependent RNA polymerase, thus blocking RNA transcription.

Rifampin can be administered by the oral route or by IV infusion. IV doses are the same as those for oral.

Tuberculosis:

• Adults: 10 mg/kg, in a single daily administration, not to exceed 600 mg/day, oral or IV
• Pediatric Patients: 10–20 mg/kg, not to exceed 600 mg/day, oral or IV

It is recommended that oral rifampin be administered once daily, either 1 hour before or 2 hours after a meal with a full glass of water.

Rifampin is indicated in the treatment of all forms of tuberculosis. A three-drug regimen consisting of rifampin, isoniazid, and pyrazinamide is recommended in the initial phase of shortcourse therapy which is usually continued for 2 months. The Advisory Council for the Elimination of Tuberculosis, the American Thoracic Society, and the Centers for Disease Control and Prevention recommend that either streptomycin or ethambutol be added as a fourth drug in a regimen containing isoniazid (INH), rifampin and pyrazinamide for initial treatment of tuberculosis unless the likelihood of INH resistance is very low. The need for a fourth drug should be reassessed when the results of susceptibility testing are known. If community rates of INH resistance are currently less than 4%, an initial treatment regimen with less than four drugs may be considered.

Following the initial phase, treatment should be continued with rifampin and isoniazid for at least 4 months. Treatment should be continued for longer if the patient is still sputum or culture positive, if resistant organisms are present, or if the patient is HIV positive.

Should be taken on an empty stomach. Best taken on an empty stomach 1 hr before or 2 hr after meals.

Facial flushing and itching, with or without a rash, flu-like syndrome characterised by episodes of fever, chills, headache, dizziness, bone pain, shortness of breath, and malaise; GI adverse effects (e.g. nausea, vomiting, anorexia, diarrhoea, epigastric distress), pseudomembranous colitis, eosinophilia, leucopenia, haemolytic anaemia; alterations in kidney function and renal failure, menstrual disturbances, oedema, myopathy, muscular weakness; orange-red discolouration of the urine, faeces, sweat, saliva, sputum, tears, and other body fluids; thrombophlebitis, local irritation and inflammation after prolonged IV infusion. Rarely, eye irritation and visual disturbances, anaphylaxis or shock.

Rifampicin is contraindicated in patients with a history of hypersensitivity to rifampin or any of the components, or to any of the rifamycins. Rifampin is contraindicated in patients who are also receiving ritonavir-boosted saquinavir due to an increased risk of severe hepatocellular toxicity.

Rifampin is contraindicated in patients who are also receiving atazanavir, darunavir, fosamprenavir, saquinavir, or tipranavir due to the potential of rifampin to substantially decrease plasma concentrations of these antiviral drugs, which may result in loss of antiviral efficacy and/or development of viral resistance.

Rifampicin has been shown to produce liver dysfunction. Fatalities associated with jaundice have occurred in patients with liver disease and in patients taking rifampin with other hepatotoxic agents. Patients with impaired liver function should be given rifampin only in cases of necessity and then with caution and under strict medical supervision. In these patients, careful monitoring of liver function, especially SGPT/ALT and SGOT/AST should be carried out prior to therapy and then every 2 to 4 weeks during therapy. If signs of hepatocellular damage occur, rifampin should be withdrawn.

In some cases, hyperbilirubinemia resulting from competition between rifampin and bilirubin for excretory pathways of the liver at the cell level can occur in the early days of treatment. An isolated report showing a moderate rise in bilirubin and/or transaminase level is not in itself an indication for interrupting treatment; rather, the decision should be made after repeating the tests, noting trends in the levels, and considering them in conjunction with the patient's clinical condition.

Rifampin has enzyme-inducing properties, including induction of delta amino levulinic acid synthetase. Isolated reports have associated porphyria exacerbation with rifampin administration.

May accelerate the metabolism and reduce the effect of drugs that are metabolised by CYP450 enzymes (e.g. quinidine, phenytoin, theophylline). Decreased concentrations of atovaquone and increased concentrations of rifampicin when taken concomitantly. Concurrent use of ketoconazole and rifampicin may result in decreased serum concentrations of both drugs. May decrease serum concentrations of enalaprilat. Reduced absorption by antacids. Increased risk of hepatotoxicity with halothane or isoniazid.

Pregnancy: When administered during the last few weeks of pregnancy, rifampin can cause post natal hemorrhages in the mother and infant for which treatment with vitamin K may be indicated.

Nursing Mothers: Because of the potential for tumorigenicity shown for rifampin in animal studies, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Geriatric Use: Clinical studies of Rifampicin did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Caution should therefore be observed in using rifampin in elderly patients.

Nausea, vomiting, abdominal pain, pruritus, headache, and increasing lethargy will probably occur within a short time after ingestion; unconsciousness may occur when there is severe hepatic disease. Transient increases in liver enzymes and/or bilirubin may occur. Brownish-red or orange discoloration of the skin, urine, sweat, saliva, tears, and feces will occur, and its intensity is proportional to the amount ingested.

Liver enlargement, possibly with tenderness, can develop within a few hours after severe overdosage; bilirubin levels may increase and jaundice may develop rapidly. Hepatic involvement may be more marked in patients with prior impairment of hepatic function. Other physical findings remain essentially normal. A direct effect upon the hematopoietic system, electrolyte levels, or acid-base balance is unlikely.

Facial or periorbital edema has also been reported in pediatric patients. Hypotension, sinus tachycardia, ventricular arrhythmias, seizures and cardiac arrest were reported in some fatal cases.

Preparation Of Solution For IV Infusion: Reconstitute the lyophilized powder by transferring 10 mL of sterile water for injection to a vial containing 600 mg of rifampin for injection. Swirl vial gently to completely dissolve the antibiotic. The reconstituted solution contains 60 mg rifampin per mL and is stable at room temperature for up to 30 hours. Prior to administration, withdraw from the reconstituted solution a volume equivalent to the amount of rifampin calculated to be administered and add to 500 mL of infusion medium. Mix well and infuse at a rate allowing for complete infusion within 3 hours. Alternatively, the amount of rifampin calculated to be administered may be added to 100 mL of infusion medium and infused in 30 minutes.

Dilutions in dextrose 5% for injection (D5W) are stable at room temperature for up to 8 hours and should be prepared and used within this time. Precipitation of rifampin from the infusion solution may occur beyond this time. Dilutions in normal saline are stable at room temperature for up to 6 hours and should be prepared and used within this time. Other infusion solutions are not recommended.

Store between 15-30° C. Avoid excessive heat and protect from light.

Lopinavir and Ritonavir is an HIV-1 protease inhibitor indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults and pediatric patients (14 days and older).

Drugs for HIV / Anti-retroviral drugs

Lopinavir and Ritonavir tablets may be taken with or without food, swallowed whole and not chewed, broken, or crushed.

Adult Patients:

• 400/100 mg (two 200/50 mg tablets) twice daily, or
• 800/200 mg (four 200/50 mg tablets) once daily in patients with less than three lopinavir resistance-associated substitutions.

Concomitant Therapy in Adults Patients: Dose adjustments of Lopinavir and Ritonavir may be needed when co-administering with efavirenz, nevirapine, or nelfinavir.
Do not use once daily administration of Lopinavir and Ritonavir in: HIV-1 infected patients with three or more of the following lopinavir resistance-associated substitutions: L10F/I/R/V, K20M/N/R, L24I, L33F, M36I, I47V, G48V, I54L/T/V, V82A/C/F/S/T, and I84V. Combination with efavirenz, nevirapine, nelfinavir, carbamazepine, phenobarbital, or phenytoin.

Commonly reported side effects included diarrhea, nausea, vomiting, hypertriglyceridemia and hypercholesterolemia.

Lopinavir and Ritonavir is contraindicated in patients with previously demonstrated clinically significant hypersensitivity (e.g., toxic epidermal necrolysis, Stevens-Johnson syndrome, erythema multiforme, urticaria, angioedema) to any of its ingredients, including lopinavir and ritonavir.

Co-administration of Lopinavir and Ritonavir is contraindicated with drugs that are highly dependent on CYP3A for clearance and for which elevated plasma concentrations are associated with serious and/or life-threatening reactions.

The following have been observed in patients receiving Lopinavir and Ritonavir:

Hepatotoxicity: Patients with underlying hepatitis B or C or marked elevations in transaminase prior to treatment may be at increased risk for developing or worsening of transaminase elevations or hepatic decompensation with use of this combination.

QT Interval Prolongation: In cases of QT interval prolongation and torsade de pointes have been reported although causality of this combination could not be established. Avoid use in patients with congenital long QT syndrome, those with hypokalemia, and with other drugs that prolong the QT interval.

PR Interval Prolongation: Lopinavir/ritonavir prolongs the PR interval in some patients. Cases of second or third degree atrioventricular block have been reported. This combination should be used with caution in patients with underlying structural heart disease, pre-existing conduction system abnormalities, ischemic heart disease or cardiomyopathies, as these patients may be at increased risk for developing cardiac conduction abnormalities.

Diabetes Mellitus/Hyperglycemia: New onset diabetes mellitus, exacerbation of pre-existing diabetes mellitus, and hyperglycemia have been reported in HIV-1 infected patients receiving protease inhibitor therapy. Some patients required either initiation or dose adjustments of insulin or oral hypoglycemic agents for treatment of these events. In some cases, diabetic ketoacidosis has occurred. In those patients who discontinued protease inhibitor therapy, hyperglycemia persisted in some cases.

Lipid Elevations: Treatment with Lopinavir and Ritonavir has resulted in large increases in the concentration of total cholesterol and triglycerides.

Co-administration of Lopinavir and Ritonavir is contraindicated with potent CYP3A inducers where significantly reduced lopinavir plasma concentrations may be associated with the potential for loss of virologic response and possible resistance and cross resistance. It is also contraindicated with Alpha 1 Adrenoreceptor Antagonist (Alfuzosin), Antimycobacterial (Rifampin), Ergot Derivatives ( Dihydroergotamine, ergotamine, methylergonovine), Gl Motility Agent (Cisapride), HMG-CoA Reductase Inhibitors (Lovastatin, simvastatin), PDE5 Enzyme Inhibitor (Sildenafil, when used for the treatment of pulmonary arterial hypertension), Neuroleptic (Pimozide) Sedative/Hypnotics (Triazolam; orally administered midazolam)

Nursing Mothers: The Centers for Disease Control and Prevention recommend that HIV-1 infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV-1. Studies in rats have demonstrated that lopinavir is secreted in milk. It is not known whether lopinavir is secreted in human milk. Because of both the potential for HIV-1 transmission and the potential for serious adverse reactions in nursing infants, mothers should be instructed not to breastfeed if they are receiving this combination

Pediatric Use: The safety, efficacy, and pharmacokinetic profiles of this combination in pediatric patients below the age of 14 days have not been established.

Human experience of acute overdosage with this combination is limited. Treatment of overdose should consist of general supportive measures including monitoring of vital signs and observation of the clinical status of the patient. There is no specific antidote for overdose with this combination. If indicated, elimination of unabsorbed drug should be achieved by gastric lavage. Administration of activated charcoal may also be used to aid in removal of unabsorbed drug. Since lopinavir is highly protein bound, dialysis is unlikely to be beneficial in significant removal of the drug. However, dialysis can remove both alcohol and propylene glycol in the case of overdose with this combination.

Keep in a dry place & store below 30° C. Protect from light & keep out of the reach of children.

Riluzole is indicated for the treatment of amyotrophic lateral sclerosis (ALS).

Neurodegenerative Disease Drugs / Neuromuscular Disorder Drugs

The mode of action of riluzole is unknown. Its pharmacological properties include the following, some of which may be related to its effect:

• An inhibitory effect on glutamate release (activation of glutamate reuptake),
• Inactivation of voltage-dependent sodium channels, 
• Ability to interfere with intracellular events that follow transmitter binding at excitatory amino acid receptors.

The recommended dosage for Riluzole is 50 mg taken orally twice daily. Riluzole should be taken at least 1 hour before or 2 hours after a meal. Measure serum aminotransferases before and during treatment with Riluzole

The following adverse reactions are described below and elsewhere in the labeling: Hepatic Injury, Neutropenia, Interstitial lung disease

Riluzole is contraindicated in patients with a history of severe hypersensitivity reactions to riluzole or to any of its components (anaphylaxis has occurred)

Hepatic Injury: Cases of drug-induced liver injury, some of which were fatal, have been reported in patients taking Riluzole. Asymptomatic elevations of hepatic transaminases have also been reported, and in some patients have recurred upon rechallenge with Riluzole.

In clinical studies, the incidence of elevations in hepatic transaminases was greater in Riluzoletreated patients than placebo-treated patients. The incidence of elevations of ALT above 5 times the upper limit of normal (ULN) was 2% in Riluzole-treated patients. Maximum increases in ALT occurred within 3 months after starting Riluzole. About 50% and 8% of Riluzoletreated patients in pooled Studies 1 and 2, had at least one elevated ALT level above ULN and above 3 times ULN, respectively 

Monitor patients for signs and symptoms of hepatic injury, every month for the first 3 months of treatment, and periodically thereafter. The use of Riluzole is not recommended if patients develop hepatic transaminases levels greater than 5 times the ULN. Discontinue Riluzole if there is evidence of liver dysfunction (e.g., elevated bilirubin).

Neutropenia: Cases of severe neutropenia (absolute neutrophil count less than 500 per mm3) within the first 2 months of Riluzole treatment have been reported. Advise patients to report febrile illnesses.

Interstitial Lung Disease: Interstitial lung disease, including hypersensitivity pneumonitis, has occurred in patients taking Riluzole. Discontinue Riluzole immediately if interstitial lung disease develops.

Strong to moderate CYP1A2 inhibitors: Coadministration may increase Riluzole-associated adverse reactions

Strong to moderate CYP1A2 inducers: Coadministration may result in decreased efficacy 

Hepatotoxic drugs: Riluzole-treated patients that take other hepatotoxic drugs may be at increased risk for hepatotoxicity

Pregnancy: Based on animal data, may cause fetal harm

Lactation: It is not known if riluzole is excreted in human milk. Riluzole or its metabolites have been detected in milk of lactating rat. Women should be advised that many drugs are excreted in human milk and that the potential for serious adverse reactions in nursing infants from Riluzole is unknown.

Reported symptoms of overdose following ingestion of Riluzole ranging from 1.5 to 3 grams (30 to 60 times the recommended dose) included acute toxic encephalopathy, coma, drowsiness, memory loss, and methemoglobinemia. No specific antidote for the treatment of Riluzole overdose is available.

Store at controlled room temperature, 20°C to 25°C, and protect from bright light.

Anti-Tubercular Antibiotics

Rifampicin suppresses initiation of chain formation for RNA synthesis in susceptible bacteria by binding to the β subunit of DNA-dependent RNA polymerase, thus blocking RNA transcription.

Rifampin can be administered by the oral route or by IV infusion. IV doses are the same as those for oral.

Tuberculosis:

• Adults: 10 mg/kg, in a single daily administration, not to exceed 600 mg/day, oral or IV
• Pediatric Patients: 10–20 mg/kg, not to exceed 600 mg/day, oral or IV

It is recommended that oral rifampin be administered once daily, either 1 hour before or 2 hours after a meal with a full glass of water.

Rifampin is indicated in the treatment of all forms of tuberculosis. A three-drug regimen consisting of rifampin, isoniazid, and pyrazinamide is recommended in the initial phase of shortcourse therapy which is usually continued for 2 months. The Advisory Council for the Elimination of Tuberculosis, the American Thoracic Society, and the Centers for Disease Control and Prevention recommend that either streptomycin or ethambutol be added as a fourth drug in a regimen containing isoniazid (INH), rifampin and pyrazinamide for initial treatment of tuberculosis unless the likelihood of INH resistance is very low. The need for a fourth drug should be reassessed when the results of susceptibility testing are known. If community rates of INH resistance are currently less than 4%, an initial treatment regimen with less than four drugs may be considered.

Following the initial phase, treatment should be continued with rifampin and isoniazid for at least 4 months. Treatment should be continued for longer if the patient is still sputum or culture positive, if resistant organisms are present, or if the patient is HIV positive.

Should be taken on an empty stomach. Best taken on an empty stomach 1 hr before or 2 hr after meals.

Facial flushing and itching, with or without a rash, flu-like syndrome characterised by episodes of fever, chills, headache, dizziness, bone pain, shortness of breath, and malaise; GI adverse effects (e.g. nausea, vomiting, anorexia, diarrhoea, epigastric distress), pseudomembranous colitis, eosinophilia, leucopenia, haemolytic anaemia; alterations in kidney function and renal failure, menstrual disturbances, oedema, myopathy, muscular weakness; orange-red discolouration of the urine, faeces, sweat, saliva, sputum, tears, and other body fluids; thrombophlebitis, local irritation and inflammation after prolonged IV infusion. Rarely, eye irritation and visual disturbances, anaphylaxis or shock.

Rifampicin is contraindicated in patients with a history of hypersensitivity to rifampin or any of the components, or to any of the rifamycins. Rifampin is contraindicated in patients who are also receiving ritonavir-boosted saquinavir due to an increased risk of severe hepatocellular toxicity.

Rifampin is contraindicated in patients who are also receiving atazanavir, darunavir, fosamprenavir, saquinavir, or tipranavir due to the potential of rifampin to substantially decrease plasma concentrations of these antiviral drugs, which may result in loss of antiviral efficacy and/or development of viral resistance.

Rifampicin has been shown to produce liver dysfunction. Fatalities associated with jaundice have occurred in patients with liver disease and in patients taking rifampin with other hepatotoxic agents. Patients with impaired liver function should be given rifampin only in cases of necessity and then with caution and under strict medical supervision. In these patients, careful monitoring of liver function, especially SGPT/ALT and SGOT/AST should be carried out prior to therapy and then every 2 to 4 weeks during therapy. If signs of hepatocellular damage occur, rifampin should be withdrawn.

In some cases, hyperbilirubinemia resulting from competition between rifampin and bilirubin for excretory pathways of the liver at the cell level can occur in the early days of treatment. An isolated report showing a moderate rise in bilirubin and/or transaminase level is not in itself an indication for interrupting treatment; rather, the decision should be made after repeating the tests, noting trends in the levels, and considering them in conjunction with the patient's clinical condition.

Rifampin has enzyme-inducing properties, including induction of delta amino levulinic acid synthetase. Isolated reports have associated porphyria exacerbation with rifampin administration.

May accelerate the metabolism and reduce the effect of drugs that are metabolised by CYP450 enzymes (e.g. quinidine, phenytoin, theophylline). Decreased concentrations of atovaquone and increased concentrations of rifampicin when taken concomitantly. Concurrent use of ketoconazole and rifampicin may result in decreased serum concentrations of both drugs. May decrease serum concentrations of enalaprilat. Reduced absorption by antacids. Increased risk of hepatotoxicity with halothane or isoniazid.

Pregnancy: When administered during the last few weeks of pregnancy, rifampin can cause post natal hemorrhages in the mother and infant for which treatment with vitamin K may be indicated.

Nursing Mothers: Because of the potential for tumorigenicity shown for rifampin in animal studies, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Geriatric Use: Clinical studies of Rifampicin did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Caution should therefore be observed in using rifampin in elderly patients.

Nausea, vomiting, abdominal pain, pruritus, headache, and increasing lethargy will probably occur within a short time after ingestion; unconsciousness may occur when there is severe hepatic disease. Transient increases in liver enzymes and/or bilirubin may occur. Brownish-red or orange discoloration of the skin, urine, sweat, saliva, tears, and feces will occur, and its intensity is proportional to the amount ingested.

Liver enlargement, possibly with tenderness, can develop within a few hours after severe overdosage; bilirubin levels may increase and jaundice may develop rapidly. Hepatic involvement may be more marked in patients with prior impairment of hepatic function. Other physical findings remain essentially normal. A direct effect upon the hematopoietic system, electrolyte levels, or acid-base balance is unlikely.

Facial or periorbital edema has also been reported in pediatric patients. Hypotension, sinus tachycardia, ventricular arrhythmias, seizures and cardiac arrest were reported in some fatal cases.

Preparation Of Solution For IV Infusion: Reconstitute the lyophilized powder by transferring 10 mL of sterile water for injection to a vial containing 600 mg of rifampin for injection. Swirl vial gently to completely dissolve the antibiotic. The reconstituted solution contains 60 mg rifampin per mL and is stable at room temperature for up to 30 hours. Prior to administration, withdraw from the reconstituted solution a volume equivalent to the amount of rifampin calculated to be administered and add to 500 mL of infusion medium. Mix well and infuse at a rate allowing for complete infusion within 3 hours. Alternatively, the amount of rifampin calculated to be administered may be added to 100 mL of infusion medium and infused in 30 minutes.

Dilutions in dextrose 5% for injection (D5W) are stable at room temperature for up to 8 hours and should be prepared and used within this time. Precipitation of rifampin from the infusion solution may occur beyond this time. Dilutions in normal saline are stable at room temperature for up to 6 hours and should be prepared and used within this time. Other infusion solutions are not recommended.

Store between 15-30° C. Avoid excessive heat and protect from light.

Rifampicin and Isoniazid belongs to a group of medicines called antituberculosis agents. It is a fixed combination of two very effective antituberculosis agents which stop the growth of mycobacteria. These mycobacteria cause tuberculosis. Rifampicin and Isoniazid is used for the continuation phase treatment of tuberculosis.

Combined anti- Tubercular Preparations

Rifampicin and isoniazid are active bactericidal anti-TB drugs which are particularly active against the rapidly growing extracellular organisms and also have bactericidal activity intracellularly. Rifampicin inhibits DNA-dependent RNA polymerase activity in susceptible cells. Specifically, it interacts with bacterial RNA polymerase but does not inhibit the mammalian enzyme. Cross-resistance to rifampicin has only been shown with other rifamycins. It has activity against slow-and intermittently-growing M. tuberculosis. Isoniazid acts against actively growing tubercle bacilli.

Body weight <50 kg: 3 tablet of 150/100 once daily or 1 tablet of 450/300 once daily
Body weight >50 kg: 2 tablet of 300/150 once daily.
Hepatic impairment: Max: 8 mg/kg daily.

Unwanted effects which may occur during continuous daily or intermittent therapy: Rifampicin: Rifampicin may cause reddish discolouration of body fluids and occasionally other body secretions eg, urine, sputum, lacrimal fluid, faeces, saliva and sweat. It may permanently discolour soft contact lenses.

Hepatic Effects: Very common (>10%) is an asymptomatic increase in liver enzymes; severe life-threatening hepatic reactions eg, hepatic failure and acute fulminant hepatitis are uncommon (>0.1% and <1%). In isolated cases (<0.01 %), a fatal outcome was observed.

Renal Effects: Elevations of BUN and serum uric acid, haemolysis, haematuria, interstitial nephritis, renal insufficiency. Gastrointestinal Effects: Nausea, abdominal pains, vomiting or diarrhoea, pseudomembranous colitis.

Central and Peripheral Nervous System Effects: Tiredness, drowsiness, headache, dizziness, ataxia, mental confusion, muscular weakness, visual disturbances. Haematological Changes: Leucopenia, eosinophilia, thrombocytopenia and thrombocytopenic purpura. Effects on Skin and Appendages: Flushing, itching with or without skin rash, urticaria, reddening of the eyes, exudative conjunctivitis or generalised hypersensitivity reactions involving the skin eg, exfoliative dermatitis, Lyell's syndrome and pemphigoid reactions. Endocrine Effects: Disturbances in the menstrual cycle, induction of crisis in Addison patients. Unwanted effects chiefly occurring during intermittent therapy or upon resumption of treatment after temporary interruption

Known or suspected hypersensitivity to rifamycins and/or to INH, and/or to any of the excipients including a history of drug-induced hepatitis; acute liver diseases, regardless of their origin; peripheral neuritis.

Use of isoniazid should be carefully monitored in the following:

• Daily users of alcohol. Daily ingestion of alcohol may be associated with a higher incidence of isoniazid hepatitis.
• Patients with active chronic liver disease or severe renal dysfunction.
• Age >35.
• Concurrent use of any chronically administered medication.
• History of previous discontinuation of isoniazid.
• Existence of peripheral neuropathy or conditions predisposing to neuropathy. Pregnancy.
• Injection drug use.
• Women belonging to minority groups, particularly in the post-partum period.
• HIV seropositive patients.

May reduce effectivity of hormonal contraceptives. Reduced absorption with antacids. May decrease plasma concentrations of antivirals (e.g. atazanavir, darunavir, fosamprenavir), atovaquone with rifampicin. Rifampicin may reduce serum levels of anticonvulsants (e.g. phenytoin), antiarrhythmics (e.g. disopyramide), oral anticoagulants, antifungals (e.g. ketoconazole), barbiturates, ?-blockers, Ca channel blockers (e.g. diltiazem), chloramphenicol, clarithromycin, corticosteroids, ciclosporin, cardiac glycosides, clofibrate, dapsone, diazepam, doxycycline, fluoroquinolones (e.g. ciprofloxacin), haloperidol, oral hypoglycemic agents (sulfonylureas), levothyroxine, methadone, narcotic analgesics, progestins, quinine, tacrolimus, theophylline, TCAs (e.g. amitriptyline, nortriptyline) and zidovudine. Increased risk of hepatotoxicity with halothane.

Isoniazid may inhibit the metabolism of anticonvulsants (e.g. carbamazepine, phenytoin), benzodiazepines (e.g. diazepam), haloperidol, ketoconazole, theophylline, and warfarin. May enhance the CNS effects of meperidine, cycloserine, and disulfiram with isoniazid. Loss of glucose control in patients on oral hypoglycaemics with isoniazid.

Pregnancy Category C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks

Combined anti- Tubercular Preparations

Rifampicin, isoniazid and pyrazinamide are all active bactericidal antituberculosis drugs. Rifampicin and isoniazid are particularly active against the rapidly growing extracellular organisms and have an intracellular bactericidal activity. Rifampicin also inhibits DNA-dependent RNA polymerase activity in susceptible cells and it has activity against slow and intermittently-growing M tuberculosis. Pyrazinamide, particularly in the acid pH environment of macrophages is active against intracellular organisms. Combination of these agents covers activity against the 3 different bacterial populations.

Total Dosage Requirement:

• Rifampicin: 10 (8-12) mg/kg body mass/day.
• Isoniazid: 5 (4-6) mg/kg body mass/day.
• Pyrazinamide: 25 (20-30) mg/kg body mass/day.

Pediatric Patients: The ratio of the drugs may not be appropriate in pediatric patients under the age of 15 (e.g., higher mg/kg doses of isoniazid are usually given in pediatric patients than adults).

The tablets should be given as a single dose, preferably on an empty stomach, at least 30 min before breakfast to ensure a high peak serum concentration.

Tablets are recommended in the initial intensive phase of the short course treatment of tuberculosis. During this phase which lasts for 2 months

Unwanted effects which may occur during continuous daily or intermittent therapy: Rifampicin: Rifampicin may cause reddish discolouration of body fluids and occasionally other body secretions eg, urine, sputum, lacrimal fluid, faeces, saliva and sweat. It may permanently discolour soft contact lenses.

Hepatic Effects: Very common (>10%) is an asymptomatic increase in liver enzymes; severe life-threatening hepatic reactions eg, hepatic failure and acute fulminant hepatitis are uncommon (>0.1% and <1%). In isolated cases (<0.01 %), a fatal outcome was observed.

Renal Effects: Elevations of BUN and serum uric acid, haemolysis, haematuria, interstitial nephritis, renal insufficiency.

Gastrointestinal Effects: Nausea, abdominal pains, vomiting or diarrhoea, pseudomembranous colitis.

Central and Peripheral Nervous System Effects: Tiredness, drowsiness, headache, dizziness, ataxia, mental confusion, muscular weakness, visual disturbances.

Haematological Changes: Leucopenia, eosinophilia, thrombocytopenia and thrombocytopenic purpura.

Effects on Skin and Appendages: Flushing, itching with or without skin rash, urticaria, reddening of the eyes, exudative conjunctivitis or generalised hypersensitivity reactions involving the skin eg, exfoliative dermatitis, Lyell's syndrome and pemphigoid reactions.

Endocrine Effects: Disturbances in the menstrual cycle, induction of crisis in Addison patients.

Unwanted effects chiefly occurring during intermittent therapy or upon resumption of treatment after temporary interruption

Known or suspected hypersensitivity to rifamycins and/or to isoniazid and to pyrazinamide and/or to any of the excipients including a history of drug-induced hepatitis, acute liver diseases regardless of their origin, and peripheral neuritis.

Caution is advised in patients with impaired renal or liver function, diabetes mellitus, chronic alcoholism and undernourished patients, patients with a history of gout and patients suffering from convulsive disorders and acute porphyria. Precautions need to be taken: Blood counts and liver function tests (SGPT, SGOT) should be performed periodically (especially in prolonged treatment) and at baseline, if possible.

Patients with current chronic liver disease or impaired liver function should be treated with caution and under strict medical supervision. Careful monitoring of liver function should be carried out and attention should be paid to possible prodromal symptoms of hepatitis eg, fatigue, weakness, malaise, anorexia, nausea or vomiting. If these symptoms appear or if signs suggestive of hepatic damage are detected, treatment should be discontinued promptly. The occurrence of severe and sometimes fatal hepatitis associated may develop even after many months of treatment.

Rifampicin may reduce effectivity of hormonal contraceptives, ACE inhibitors (e.g. enalapril, imidapril), antiemetics (e.g. aprepitant), antineoplastics (e.g. imatinib), diuretics (e.g. eplerenone), drugs for erectile dysfunction (e.g. tadalafil), oral hypoglycaemics (e.g. nateglinide, repaglinide), NSAIDs (e.g. etoricoxib). Rifampicin may reduce serum levels of atovaquone, ketoconazole. Antacids may reduce absorption of rifampicin. Anaesthetics and halothane may increase risk for hepatotoxicity with rifampicin and isoniazid.

Isoniazid may increase serum levels of phenytoin and theophylline; and may decrease carbamazepine metabolism. Stavudine may increase risk of distal sensory neuropathy with isoniazid. Antacids may reduce isoniazid absorption. May increase plasma levels of isoniazid with para-aminosalicylic acid. Increased risk of CNS toxicity when isoniazid is used concomitantly with cycloserine.

Pyrazinamide antagonizes the effects of probenecid and sulfinpyrazone.

Potentially Fatal: Concominant use with saquinavir/ritonavir may increase risk of severe hepatotoxicity. May reduce antiviral efficacy of atazanavir, darunavir, fosamprenavir, saquinavir, or tipranavir

Pregnancy Category C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks

Should be stored in cool and dry place

St. John’s Wort is indicated in-

• Depression
• Insomnia
• Seasonal Affective Disorder (SAD)
• Obsessive Compulsive Disorder (OCD)

Herbal and Nutraceuticals

St. John’s Wort is an herb which is most commonly used to treat for mild to moderate depression and conditions that sometimes go along with depression such as anxiety, tiredness, loss of appetite and insomnia. The main components of St. John’s Wort are Hypericin and Hyperforin which are responsible for its effects against depression. Although the exact mechanism of action of St. John’s Wort is unknown but it may inhibit the reuptake of Serotonin and Noradrenaline, inhibit Monoamine Oxidase (MAO), up-regulate Serotonin receptor, and reduce depression.

The recommended dose of St. John’s Wort capsule in adults is 1 capsule 3 times daily or as prescribed by the physician.

St. John’s Wort is generally safe for most people. It sometimes may cause dry mouth, dizziness, constipation and diarrhea.

St. John’s Wort should be used cautiously with drugs metabolized by Cytochrome P450 and drugs that lower the seizure threshold.

Symptoms of St. John’s Wort overdose may include dry mouth, dizziness and diarrhea.

St. John’s Wort is not recommended for use during pregnancy.Because of the possible risk to the infant, breast-feeding while using this drug is not recommended.

Keep out of reach of the children. Keep away from direct sunlight; store in a cool and dry place.

Treatment of both pulmonary and extrapulmonary tuberculosis in the intensive initial phase of treatment.

Combined anti- Tubercular Preparations

Rifampicin: It is a semisynthetic derivative of rifamycin, suppresses bacterial RNA synthesis by binding to the β-subunit of DNA-dependent RNA polymerase, thus inhibiting the attachment of the enzyme to DNA, blocking RNA transcription and elongation. It does not inhibit the counterpart mammalian enzyme.
Rifampicin has a bactericidal action and a potent sterilizing effect against both intracellular and extracellular tubercle bacilli. Cross-resistance has been shown only with other rifamycin derivatives.

Isoniazid: It kills actively growing tubercle bacilli by inhibiting the biosynthesis of mycolic acids, which are the major components of the bacterial cell wall of Mycobacterium tuberculosis.

Pyrazinamide: Pyrazinamide, an antituberculous drug, is the pyrazine analog of nicotinamide. The precise mechanism of action of pyrazinamide is not known. Its metabolite, pyrazinoic acid, which is less active in vitro may possibly be involved in the in vivo activity of pyrazinamide.

Ethambutol: Ethambutol diffuses slowly into actively growing Mycobacteria cells eg, tubercle bacilli. It inhibits the synthesis of 1 or more metabolites, thus causing impaired cell metabolism, arrest cell multiplication and induce cell death. No cross-resistance with other agents has been demonstrated.

Spectrum of Activity: Rifampicin, isoniazid, pyrazinamide, and ethambutol, at therapeutic levels, have demonstrated bactericidal activity against both intracellular and extracellular Mycobacterium tuberculosis organism.

Adults: 3 tablets/day for an average body weight of 50 kg.

Patients weighing- 

• >70 kg: 5 tablets
• 55-70 kg: 4 tablets
• 38-54 kg: 3 tablets
• 30-37 kg: 2 tablets

All doses to be taken once daily for 2 months on intensive phase.

Rifampicin: Reddish discolouration of body fluids, asymptomatic increase in liver enzymes, elevations of BUN & uric acid, hemolysis, hematuria, intestinal nephritis, renal insufficiency, Gl discomfort, CNS effects, hematological changes, skin rash, endocrine effects.

Isoniazid: Disturbances of liver function, hepatitis, Gl disturbances, peripheral neuropathy, dizziness, lightheadedness, hematological changes, allergic reactions.

Pyrazinamide: Transient rise in serum transaminases, hepatotoxicity, hepatomegaly, jaundice, hyperuricemia, intestinal nephritis, dysuria, Gl disturbances, hematological changes, allergic reactions.

Ethambutol: Confusion, disorientation, headache, visual disturbances, jaundice, transient liver dysfunction, Gl disturbances, hematological changes, allergic effects, acute gout (rare).

Hypersensitivity to rifampicin, isoniazid, pyrazinamide or ethambutol.

Isoniazid: Previous isoniazid-associated hepatic injury; severe adverse reactions to isoniazid eg, fever, chills and arthritis; acute liver disease of any etiology, a history of previous hypersensitivity reaction to isoniazid including drug-induced hepatitis.

Children <8 year or patients who are not able to communicate visual disturbances. Check visual ability before starting treatment & monitor during treatment.

Rifampicin: Induces microsomal enzymes (accelerates clearance of methadone, oral anticoagulants, glucocorticoids, oestrogen, oral hypoglycaemic agents, digitoxin, antiarrhythmics, theophylline, anticonvulsants, azole antifungal, cyclosporin).

Isoniazid: Inhibits metabolism of antiepileptics, benzodiazepines, warfarin, theophylline. Increases metabolism of enflurane. Alcohol, ASA, Al-containing antacids, corticosteroids, ketoconazole, propranolol.

Pyrazinamide: Decreases efficacy of gout therapy agents.

Ethambutol: Neurotoxic agents.

Rifampicin: Since rifampicin has been reported to cross the placental barrier and appear in cord blood and in maternal milk, neonates and newborns of rifampicin-treated mothers should be carefully observed for any evidence of untoward effects.

Ethambutol: While administration of ethambutol to pregnant human patients has produced no detectable effect upon the fetus, the possible teratogenic potential in women capable of bearing children would be weighed carefully against the benefits of therapy. There are published reports of 5 women who received ethambutol during pregnancy without apparent adverse effect upon the fetus.

Use in children: Ethambutol is not recommended for use in children <13 years since safe conditions for use have not been established.

Store at temperatures not exceeding 30°C.

Ipratropium Nebuliser Solution is indicated as a bronchodilator for maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease, including chronic bronchitis and emphysema.

Anticholinergic bronchodilators

Ipratropium Bromide is a quaternary ammonium compound with anticholinergic properties. It appears to inhibit vagal reflexes by antagonising the action of acetylcholine (the transmitter agent released from the vagus nerve). Anticholinergics prevent the increase in intracellular concentration of cyclic guanosine monophosphate (cyclic GMP) caused by interaction of acetylcholine with the muscarinic receptor on bronchial smooth muscle.

Children over 3 years: The usual dose is 0.4-2.0 ml Ipratropium Bromide Solution (100-500 micrograms) up to three times daily. 

Adults (including elderly and adolescents) over 12 years of age: The usual dose is 0.4-2.0 ml Ipratropium Bromide Solution (100-500 micrograms) up to four times daily.

Allergic-type reactions such as skin rash, angio-oedema of the tongue, lips and face, urticaria (including giant urticaria), laryngospasm and anaphylactic reactions have been reported, with positive rechallenge in some cases.

Ipratropium Bromide solution should not be taken by patients with known hypersensitivity to atropine or its derivatives or to any other component of the product.

Ipratropium Bromide should be used with caution in patients predisposed to narrow-angle glaucoma, or with prostatic hyperplasia or bladder-neck obstruction.

The safety of Ipratropium Bromide during human pregnancy has not been established. The benefits of using Ipratropium Bromide during a confirmed or suspected pregnancy must be weighed against possible hazards to the unborn child. It is not known whether Ipratropium Bromide is excreted into breast milk.

Should be stored in cool and dry place

Intravenous fluid preparations

Lactated Ringer's solution contains isotonic concentrations of electrolytes in water for inj. It is used for parenteral replacement of extracellular losses of fluid and electrolytes. Lactated Ringer’s Injection, produces a metabolic alkalinizing effect. Lactate ions are metabolized ultimately to carbon dioxide and water, which requires the consumption of hydrogen cations.

Calcium chloride is used to prevent or treat negative calcium balance. It also regulates action potential excitation threshold to facilitate nerve and muscle performance.

Potassium chloride is a major cation of the intracellular fluid. It plays an active role in the conduction of nerve impulses in the heart, brain and skeletal muscle; contraction of cardiac skeletal and smooth muscles; maintenance of normal renal function, acid-base balance, carbohydrate metabolism and gastric secretion.

Sodium chloride is the major extracellular cation. It is important in electrolyte and fluid balance, osmotic pressure control and water distribution as it restores sodium ions. It is used as a source of electrolytes and water for hydration, treatment of metabolic acidosis, priming solution in haemodialysis and treatment of hyperosmolar diabetes. It is also used as diluents for infusion of compatible drug additives.

The IV dose of Ringer's lactate solution is usually calculated by estimated fluid loss and presumed fluid deficit. For fluid resuscitation the usual rate of administration is 20 to 30 ml/kg body weight/hour. RL is not suitable for maintenance therapy (i.e., maintenance fluids) because the sodium content (130 mEq/L) is considered too low, particularly for children, and the potassium content (4 mEq/L) is too low, in view of electrolyte daily requirement. Moreover, since the lactate is converted into bicarbonate, longterm use will cause patients to become alkalotic. Ringer's lactate and other crystalloids are also used as vehicles for the IV delivery of drugs.

In a large-volume resuscitation over several hours, LRS maintains a more stable blood pH than normal saline.

Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia.

Hypersensitivity.

IV infusion is obsolete in metabolic acidosis and carries the risk of producing lactic acidosis, particularly in seriously ill patients with poor tissue perfusion and on impaired hepatic function.

There are no known drug interactions and none well documented.

Pregnancy Category C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks

Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when 5% Dextrose in Lactated Ringer’s Injection is administered to a nursing woman.

Ebastine is indicated for the symptomatic treatment of:

• Seasonal and Perennial Allergic Rhinitis.
• Chronic Idiopathic Urticaria.

Non-sedating antihistamines

Ebastine is a long-acting and selective H1-histamine receptor antagonist. After repeated administration, inhibition of peripheral receptors remains at a constant level. Ebastine is rapidly absorbed and undergoes extensive first-pass metabolism following oral administration. Ebastine is almost totally converted to the pharmacologically active acid metabolite, carebastine.

Tablet:

• Adults (more than 12 years of age): 10 mg (one tablet) once daily.
• Children (6-12 years of age): 5 mg (half tablet) once daily.

Syrup:

• Children (2-5 years of age): 2.5 ml once daily (upto 5 ml in severe cases such as Perennial Allergic Rhinitis).
• Children (6-12 years of age): 5 ml once daily (upto 10 ml in severe cases such as Perennial Allergic Rhinitis).

Ebastine may be taken with or without food.

The most common side-effects are headache, dry mouth and drowsiness. Less commonly reported side effects include abdominal pain, dyspepsia, nausea and insomnia.

Patients with a known hypersensitivity to Ebastine or any of its ingredients.

Ebastine in combination with either ketoconazole or erythromycin increases in plasma level of ebastine and prolonged QTc interval. Ebastine does not interact with the pharmacokinetics of theophylline, warfarin, cimetidine, diazepam or alcohol. The sedation effect of alcohol and diazepam may be enhanced.

No clinically meaningful signs or symptoms were observed up to 100 mg given once daily. There is no specific antidote for Ebastine. In case of accidental overdoses, gastric lavage, monitoring of vital functions including ECG and symptomatic treatment should be carried out.

Store below 30°C at a cool and dry place, away from light. Keep out of reach of children

Bilastine is indicated for symptomatic treatment of allergic rhino-conjunctivitis (seasonal and perennial) and urticaria.

Non-sedating antihistamines

Bilastine is a non-sedating, long-acting histamine antagonist with selective peripheral H 1 receptor antagonist affinity and no affinity for muscarinic receptors. Bilastine inhibits histamine-induced wheal and flare skin reactions for 24 hours following single doses.

Adults & adolescents (12 years of age and over): 20 mg tablet once daily for symptomatic relief of allergic rhinitis, urticaria and allergic rhinoconjunctivitis. The maximum recommended daily dose is 20 mg Bilastine (1 tablet) and should not be exceeded. If a dose is missed, the next scheduled dose should be taken. An extra dose should not be taken. 20 mg Bilastine tablet (1 tablet) once daily should be swallowed with water on an empty stomach to achieve optimal exposure to Bilastine.

Children between 6 to 11 years: 10 mg mouth dissolving tablet for the symptomatic relief of allergic rhinitis, allergic rhinoconjunctivitis and urticaria. The Mouth dissolving tablet is for oral use only. It should be placed in the mouth. It will disperse rapidly in saliva and can be easily swallowed. Alternatively, the mouth dissolving tablet can be dispersed in a tea spoon of water before being swallowed by the children. The maximum recommended daily dose for children in between 6 to 11 years is 10 mg Bilastine mouth dissolving tablet (1 tablet) and should not be exceeded. If a dose is missed, the next scheduled dose should be taken. An extra dose should not be taken.

Children between 2 to 11 years: 4 ml once daily.

The most commonly reported side effects in clinical trial are headache, dizziness, somnolence and fatigue. These adverse events occurred with a comparable frequency in patients receiving placebo.

Bilastine is contraindicated in patients with hypersensitivity to the active substance or to any of the excipients of the tablet.

Co-administration of Bilastine and P-glycoprotein inhibitors (e.g. Ketoconazole, Erythromycin, Cyclosporine, Ritonavir or Diltiazem) should be avoided in patients with moderate or severe renal impairment.

Concomitant intake of Bilastine and Ketoconazole or Erythromycin or Diltiazem increased C max of Bilastine. The psychomotor performance after concomitant intake of alcohol and Bilastine was similar to that observed after intake of alcohol and placebo. Concomitant intake of Bilastine and Lorazepam 3 mg for 8 days did not potentiate the depressant CNS effects of Lorazepam.

There are no or limited amount of data from the use of Bilastine in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity, parturition or postnatal development. As a precautionary measure, it is preferable to avoid the use of Bilastine during pregnancy. The excretion of Bilastine in milk has not been studied in humans. A decision must be made taking into account the benefit of breast-feeding for the child and the benefit of Bilastine therapy for the mother.

Efficacy and safety of Bilastine in children under 2 years of age have not been established and there is little clinical experience in children aged 2 to 5 years, therefore Bilastine should not be used in these age groups.

In clinical trials, after administration of Bilastine at doses 10 to 11 times the therapeutic dose (220 mg as single dose; or 200 mg/day for 7 days) frequency of treatment-emergent adverse events was two times higher than with placebo. The adverse reactions most frequently reported were dizziness, headache and nausea. No serious adverse events and no significant prolongation in the QTc interval were reported.

Keep below 30°C temperature, protected from light and moisture. Keep out of reach of children.

Levocetirizine is indicated in the treatment of symptoms associated with allergic conditions such as perennial allergic rhinitis, seasonal allergic rhinitis and chronic idiopathic urticaria.

Non-sedating antihistamines

This preparation contains Levocetirizine Dihydrochloride. Levocetirizine is the active (Levo) isomer of cetirizine. It is a new highly effective and well-tolerated nonsedating antihistamine with potent antiallergic properties. It has a two-fold higher affinity for H1 receptors than cetirizine. Levocetirizine has a rapid and long-acting action, allowing once-a-day administration.

Adult and children 12 years of age and older: The recommended dose is 5 mg once daily.

Children 6 to 11 years of age: The recommended dose is 2.5 mg (1/2 tablet or 1 teaspoon oral solution) once daily.

Children 6 months to 5 years of age: The recommended dose is 1.25 mg (1/2 teaspoon oral solution) once daily.

Generally, levocetirizine is well tolerated. However, a few side effects like headache, dry mouth, fatigue and skin rash have been reported rarely.

Hypersensitivity to levocetirizine, cetirizine or its parent compound hydroxyzine. Patients with severe renal impairment (creatinine clearance: <10 ml/min) should not be administered levocetirizine.

Epileptic patients and patients at risk of convulsions. Renal impairment. Pregnancy and lactation.

Levocetirizine is not known to have any interactions with other drugs.

Pregnancy Catagory B. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, levocetirizine should be used during pregnancy only if clearly needed. Since levocetirizine is excreted in breast milk it is not recommended for use by nursing mothers.

Pediatric use: The recommended dose for the treatment of the uncomplicated skin manifestations of chronic idiopathic urticaria in patients 6 months to 17 years of age is based on extrapolation of efficacy from adults 18 years of age and older.

Geriatric use: In clinical studies, each approved indication did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently than younger patients.

Hepatic impairment: No dosage adjustment is required in patients with solely hepatic impairment.

Renal impairment:

• Mild renal impairment (creatinine clearance: 50-80 ml/min): a dose of 2.5 mg once daily is recommended.
• Moderate renal impairment (creatinine clearance: 30-50 ml/min): a dose of 2.5 mg once every other day is recommended.
• Severe renal impairment (creatinine clearance: 10-30 ml/min): a dose of 2.5 mg twice weekly (administered once every 3-4 days) is recommended.
• End-stage renal disease patients (creatinine clearance: <10 ml/min) and patients undergoing hemodialysis: should not receive Levocetirizine.

No clinically relevant adverse events have been reported in case of overdose. However in the event of overdosage, symptomatic and supportive treatment is recommended.

Store at a temperature not exceeding 30°C in a dry place. Protect from light.
