Therapeutic classView
Primary anti-epileptic drugs
PharmacologyView
Sodium Valproate, the active ingredient of this preparation is endowed with anti-epileptic activity against a variety of seizures. The mechanism by which Sodium Valproate exerts its anti-epileptic effects has not been established. However, it has been suggested that its activity is related to increase brain levels of gamma-aminobutyric acid (GABA).
DosageView
Sodium Valproate tablets may be given once or twice daily. Sodium Valproate syrup should be given in divided doses.
Epilepsy-
Bipolar disorder: Initially 20-30 mg/kg/day in 2-3 divided doses; adjust dosage in 3-5 days. Maintenance dosage is 1000-2000 mg/day.
Prophylaxis of migraine: 300 mg twice daily, although some may require 1000 mg daily.
Epilepsy-
- Adults: Initially 600 mg daily given in 2 divided doses, preferably after food, increasing by 200 mg/day at 3-day intervals to a maximum of 2.5 g daily in divided doses until control of seizure is achieved. Usual maintenance dose is 1-2 g daily (20-30 mg/kg daily)
- Children (up to 20 kg): Initially 20 mg/kg daily in divided doses, may be increased provided plasma concentrations monitored (above 40 mg/kg daily also monitor clinical chemistry and hematological parameters).
- Children (over 20 kg): Initially 400 mg daily in divided doses increased until control (usually in the range of 20-30 mg/kg daily) Maximum 35 mg/kg daily.
Bipolar disorder: Initially 20-30 mg/kg/day in 2-3 divided doses; adjust dosage in 3-5 days. Maintenance dosage is 1000-2000 mg/day.
Prophylaxis of migraine: 300 mg twice daily, although some may require 1000 mg daily.
Side effectsView
The most common side effects are anorexia, nausea and vomiting. However, these side effects are minimized with the use of enteric coated tablets. Effects on the CNS include sedation, ataxia and tremor. These symptoms occur infrequently and usually respond to a decrease in doses. Rash, alopecia and stimulation of appetite have been observed occasionally. Sodium Vaiproate has several effects on hepatic function of which elevation of liver enzymes in plasma is observed in up to 40% of patients and often occurs asymptomatically during the first few months of therapy. Rarely a fulminate hepatitis that may be fatal may develop. Children below 2 years of age with other medical conditions and those being treated with multiple antiepileptic agents are specially prone to suffer from hepatic injury, acute pancreatitis and hyperammonemia have also been frequently associated with the use of Sodium Valproate.
ContraindicationsView
Sodium Valproate is contraindicated to patients who have known hypersensitivity to the drug and liver dysfunction. Use of Sodium Valproate is restricted during pregnancy and in women of childbearing potential.
PrecautionsView
Liver functions should be monitored before therapy and during first 6 months especially in patients most at risk, No undue potential for bleeding before starting and before major surgery must be ensured, Care should be taken in renal impairment, pregnancy, breast-feeding and systemic lupus erythematosus. Sodium Valproate is partially eliminated in the urine as a ketone metabolite, which may lead to a false interpretation of the urine ketone test. Sudden withdrawal of therapy should be avoided. Sodium Valproate should not be used during pregnancy and in women of childbearing potential.
InteractionsView
Sodium Vaiproate appears to act as a non specific inhibitor of drug metabolism. Drugs to which it interacts most significantly are Phenobarbital, Phenytoin, Warfarin, Aspirin etc.
Pregnancy & lactationView
Sodium Vaiproate crosses the placenta and in humans, exposure to valproate in the first trimester has been associated with neural tube defects such as anencephaly and spina bifida in newborn. Pregnant women treated with Sodium Vaiproate should be offered to estimate serum a-fetoprotein. Sodium Valproate is excreted in breast miik. However, breast-feeding by a mother taking Sodium Valproate probably causes no risk to the child.
StorageView
Do not store above 30°C. Keep away from light and out of the reach of children.

Clonazepam
Indication detailsView
It is indicated for the treatment of panic disorder, with or without agoraphobia. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks.
It is also indicated alone or as an adjunct in the treatment of the Lennox-Gastaut Syndrome (petit mal variant), akinetic and myoclonic seizures. It may be indicated in patients with absence seizures (petit mal) who have failed to respond to succinimides.
The effectiveness of Clonazepam in long-term use, that is, for more than 9 weeks, has not been systematically studied in controlled clinical trials. The physician who elects to use Clonazepam for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

Adjunct anti-epileptic drugs, Benzodiazepine hypnotics
PharmacologyView
Clonazepam exhibits pharmacological properties which are common to benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects. The central actions of benzodiazepines are mediated through an enhancement of the GABAergic neurotransmission at inhibitory synapses. In the presence of benzodiazepines the affinity of the GABA receptor for the neurotransmitter is enhanced through positive allosteric modulation resulting in an increased action of released GABA on the postsynaptic transmembrane chloride ion flux.
There are also animal data showing an effect of clonazepam on serotonin. Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absences seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations as well as irregular spikes and waves. Generalized EEG abnormalities are more regularly suppressed than focal abnormalities. According to these findings clonazepam has beneficial effects in generalized and focal epilepsies.

DosageView
Oral:
Injection:
- Adults: The initial dose for adults with seizure disorders should not exceed 1.5 mg/day divided into three doses. Dosage may be increased in increments of 0.5 to 1 mg every 3 days until seizures are adequately controlled or until side effects preclude any further increase. Maintenance dosage must be individualized for each patient depending upon response. Maximum recommended daily dose is 20 mg.
- The initial dose for adults with panic disorder is 0.25 mg given in two divided dose. An increase to the target dose for most patients of 1 mg/day may be made after 3 days.
- Pediatric Patients: In order to minimize drowsiness, the initial dose for infants and children (up to 10 years of age or 30 kg of body weight) should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in two or three divided doses.
Injection:
- Infants and children: half of a vial (0.5 mg) by slow IV injection or by IV infusion.
- Adults: 1 vial (1 mg) by slow IV injection or by IV infusion. This dose can be repeated as required (1-4 mg are usually sufficient to reverse the status). In adults, the rate of injection must not exceed 0.25 - 0.5 mg per minute (0.5-1.0 ml of the prepared solution) and a total dose of 10 mg should not be exceeded.
Side effectsView
The most frequently occurring side effects of Clonazepam are referable to CNS depression. Experience in treatment of seizures has shown that drowsiness has occurred in approximately 50% of patients and ataxia in approximately 30%. In some cases, these may diminish with time; behavior problems have been noted in approximately 25% of patients. Abnormal eye movements, aphonia, coma, tremor, vertigo, confusion, depression, amnesia, hallucinations, hysteria, increased libido, insomnia, psychosis & palpitations may also occur.
ContraindicationsView
It should not be used in patients with a history of hypersensitivity to benzodiazepines, nor in patients with clinical or biochemical evidence of significant liver disease. It may be used in patients with open angle glaucoma who are receiving appropriate therapy but is contraindicated in acute narrow angle glaucoma.
PrecautionsView
When used in patients in whom several different types of seizure disorders coexist, Clonazepam may increase the incidence or precipitate the onset of generalized tonic-clonic seizures. This may require the addition of appropriate anticonvulsants or an increase in their dosages. The concomitant use of valproic acid and Clonazepam may produce absence status.
InteractionsView
Clonazepam does not appear to alter the pharmacokinetics of phenytoin, carbamazepine or phenobarbital. The effect of Clonazepam on the metabolism of other drugs has not been investigated.
Pregnancy & lactationView
Pregnancy: From preclinical studies it cannot be excluded that clonazepam possesses the possibility of producing congenital malformations. From epidemiological evaluations there is evidence that anticonvulsant drugs act as teratogens. However, it is difficult to determine from published epidemiological reports which drug or combination of drugs is responsible for defects in the newborn. The possibility also exists that other factors e.g. genetic factors or the epileptic condition itself may be more important than drug therapy in leading to birth defects. Under these circumstances, the drug should only be administered to pregnant women if the potential benefits outweigh the risk to the foetus. During pregnancy, Clonazepam may be administered only if there is a compelling indication. Administration of high doses in the last trimester of pregnancy or during labour can cause irregularities in the heartbeat of the unborn child and hypothermia, hypotonia, mild respiratory depression and poor feeding in the neonate. It should be borne in mind that both pregnancy itself and abrupt discontinuation of the medication can cause exacerbation of epilepsy. Withdrawal symptoms in newborn infants have occasionally been reported with benzodiazepines.
Nursing Mothers: Although the active ingredient of Clonazepam has been found to pass into the maternal milk in small amounts only, mothers undergoing treatment with this drug should not breastfeed. If there is a compelling indication for Clonazepam, breastfeeding should be discontinued.

Pediatric usageView
Pediatric Use: In infants and small children Rivotril may cause increased production of saliva and bronchial secretion. Therefore special attention must be paid to maintaining patency of the airways.
Geriatric Use: Benzodiazepine pharmacologic effects appear to be greater in elderly patients than in younger patients even at similar plasma benzodiazepine concentrations, possibly because of age-related changes in drug–receptor interactions, post-receptor mechanisms and organ function.
Renal Impairment: Renal impairment does not affect the pharmacokinetics of clonazepam. Based on pharmacokinetic criteria, no dose adjustment is required in patients with renal impairment.
Hepatic Impairment: Plasma protein binding of clonazepam in cirrhotic patients is significantly different from that in healthy subjects (free fraction 17.1±1.0% vs 13.9±0.2%). Although the influence of hepatic impairment on clonazepam pharmacokinetics has not been further investigated, experience with another closely related nitrobenzodiazepine (nitrazepam) indicates that clearance of unbound clonazepam might be reduced in liver cirrhosis.

Overdose effectsView
Symptoms: Benzodiazepines commonly cause drowsiness, ataxia, dysarthria and nystagmus. Overdose of Clonazepam is seldom life-threatening if the drug is taken alone, but may lead to areflexia, apnoea, hypotension, cardiorespiratory depression and coma. Coma, if it occurs, usually lasts a few hours but it may be more protracted and cyclical, particularly in elderly patients. Increased frequency of seizures may occur in patients at supratherapeutic plasma concentrations. Benzodiazepine respiratory depressant effects are more serious in patients with respiratory disease. Benzodiazepines increase the effects of other central nervous system depressants, including alcohol.
Treatment: Monitor the patient’s vital signs and institute supportive measures as indicated by the patient’s clinical state. In particular, patients may require symptomatic treatment for cardiorespiratory effects or central nervous system effects. Further absorption should be prevented using an appropriate method e.g. treatment within 1-2 hours with activated charcoal. If activated charcoal is used airway protection is imperative for drowsy patients. In case of mixed ingestion gastric lavage may be considered, however not as a routine measure. If CNS depression is severe consider the use of flumazenil, a benzodiazepine antagonist. This should only be administered under closely monitored conditions. It has a short half-life (about an hour), therefore patients administered flumazenil will require monitoring after its effects have worn off. Flumazenil is to be used with extreme caution in the presence of drugs that reduce seizure threshold (e.g. tricyclic antidepressants). Refer to the prescribing information for flumazenil, for further information on the correct use of this drug.

ReconstitutionView
Slow intravenous injection: The contents of the vial must be diluted with 1 ml of water for injection prior to administration so as to avoid local irritation of the veins. The injection solution should be prepared immediately before use. IV injection should be administered slowly with continuous monitoring of EEG, respiration and blood pressure.
Intravenous infusion: Clonazepam (the vial) can be diluted for infusion in a ratio of 1 vial (1 mg) to at least 85 ml diluting media. The diluting media can be any of the following: sodium chloride 0.9%; sodium chloride 0.45% + glucose 2.5%; glucose 5% or glucose 10%. These mixtures are stable for 24 hours at room temperature. Infusion bags other than PVC should be used for infusing Clonazepam. If PVC infusion bags are used then the mixture should be infused immediately or within 4 hours. The infusion time should not exceed 8 hours. Do not prepare Clonazepam infusions using sodium bicarbonate solution, as precipitation of the solution may occur.
Intramuscular injection: The IM route should be used only in exceptional cases or if IV administration is not feasible.

Pediatric usageView
Pediatric Use: In infants and small children Rivotril may cause increased production of saliva and bronchial secretion. Therefore special attention must be paid to maintaining patency of the airways.
Geriatric Use: Benzodiazepine pharmacologic effects appear to be greater in elderly patients than in younger patients even at similar plasma benzodiazepine concentrations, possibly because of age-related changes in drug–receptor interactions, post-receptor mechanisms and organ function.
Renal Impairment: Renal impairment does not affect the pharmacokinetics of clonazepam. Based on pharmacokinetic criteria, no dose adjustment is required in patients with renal impairment.
Hepatic Impairment: Plasma protein binding of clonazepam in cirrhotic patients is significantly different from that in healthy subjects (free fraction 17.1±1.0% vs 13.9±0.2%). Although the influence of hepatic impairment on clonazepam pharmacokinetics has not been further investigated, experience with another closely related nitrobenzodiazepine (nitrazepam) indicates that clearance of unbound clonazepam might be reduced in liver cirrhosis.

Overdose effectsView
Symptoms: Benzodiazepines commonly cause drowsiness, ataxia, dysarthria and nystagmus. Overdose of Clonazepam is seldom life-threatening if the drug is taken alone, but may lead to areflexia, apnoea, hypotension, cardiorespiratory depression and coma. Coma, if it occurs, usually lasts a few hours but it may be more protracted and cyclical, particularly in elderly patients. Increased frequency of seizures may occur in patients at supratherapeutic plasma concentrations. Benzodiazepine respiratory depressant effects are more serious in patients with respiratory disease. Benzodiazepines increase the effects of other central nervous system depressants, including alcohol.
Treatment: Monitor the patient’s vital signs and institute supportive measures as indicated by the patient’s clinical state. In particular, patients may require symptomatic treatment for cardiorespiratory effects or central nervous system effects. Further absorption should be prevented using an appropriate method e.g. treatment within 1-2 hours with activated charcoal. If activated charcoal is used airway protection is imperative for drowsy patients. In case of mixed ingestion gastric lavage may be considered, however not as a routine measure. If CNS depression is severe consider the use of flumazenil, a benzodiazepine antagonist. This should only be administered under closely monitored conditions. It has a short half-life (about an hour), therefore patients administered flumazenil will require monitoring after its effects have worn off. Flumazenil is to be used with extreme caution in the presence of drugs that reduce seizure threshold (e.g. tricyclic antidepressants). Refer to the prescribing information for flumazenil, for further information on the correct use of this drug.

ReconstitutionView
Slow intravenous injection: The contents of the vial must be diluted with 1 ml of water for injection prior to administration so as to avoid local irritation of the veins. The injection solution should be prepared immediately before use. IV injection should be administered slowly with continuous monitoring of EEG, respiration and blood pressure.
Intravenous infusion: Clonazepam (the vial) can be diluted for infusion in a ratio of 1 vial (1 mg) to at least 85 ml diluting media. The diluting media can be any of the following: sodium chloride 0.9%; sodium chloride 0.45% + glucose 2.5%; glucose 5% or glucose 10%. These mixtures are stable for 24 hours at room temperature. Infusion bags other than PVC should be used for infusing Clonazepam. If PVC infusion bags are used then the mixture should be infused immediately or within 4 hours. The infusion time should not exceed 8 hours. Do not prepare Clonazepam infusions using sodium bicarbonate solution, as precipitation of the solution may occur.
Intramuscular injection: The IM route should be used only in exceptional cases or if IV administration is not feasible.

- To relieve from chronic heartburn symptoms and other symptoms associated with GERD
- For the healing of erosive esophagitis
- For maintenance of healing of erosive esophagitis
- In combination with amoxicillin and clarithromycin for eradication of Helicobacter pylori infection in patients with duodenal ulcer disease.

PharmacologyView
Esomeprazole is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+-ATPase in the gastric parietal cell. Esomeprazole (S-isomer of omeprazole) is the first single optical isomer of proton pump inhibitor, provides better acid control than racemic proton pump inhibitors.
Absorption: Esomeprazole capsules contain an enteric-coated pellet formulation of esomeprazole magnesium. After oral administration peak plasma levels (Cmax) occur at approximately 1.5 hours (Tmax). The Cmax increases proportionally when the dose is increased, and there is a three-fold increase in the area under the plasma concentration-time curve (AUC) from 20 to 40 mg. At repeated once daily dosing, the systemic bioavailability is approximately 90% compared to 64% after a single dose. The AUC after administration of a single dose of esomeprazole is decreased by 33-53% after food intake compared to fasting conditions. Esomeprazole should be taken at least one hour before meals.
Distribution: Esomeprazole is 97% bound to plasma proteins. Plasma protein binding is constant over the concentration range of 2 20 mmol/L. The apparent volume of distribution at steady state in healthy volunteers is approximately 16 L.
Metabolism: Esomeprazole is extensively metabolized in the liver by the cytochrome P450 (CYP) enzyme system. The metabolites of esomeprazole lack anti-secretory activity. The major part of esomeprazole’s metabolism is dependent upon the CYP2C19 isoenzyme, which forms the hydroxy and desmethyl metabolites. The remaining amount is dependent on CYP3A4 which forms the sulphone metabolite.
Excretion: The plasma elimination half-life of esomeprazole is approximately 1–1.5 hours. Less than 1% of parent drug is excreted in the urine. Approximately 80% of an oral dose of esomeprazole is excreted as inactive metabolites in the urine, and the remainder is found as inactive metabolites in the faeces.
Combination Therapy with Antimicrobials: Esomeprazole magnesium 40 mg once daily is given in combination with clarithromycin 500 mg twice daily and amoxicillin 1000 mg twice daily for 7 days. The mean steady state AUC and Cmax of Esomeprazole increased by 70% and 18%, respectively, during triple combination therapy compared to treatment with Esomeprazole alone. The pharmacokinetic parameters for clarithromycin and amoxicillin are similar during triple combination therapy and administration of each drug alone. However, the mean AUC and Cmax for 14-hydroxyclarithromycin are increased by 19% and 22%, respectively, during triple combination therapy compared to treatment with clarithromycin alone. This increase in exposure to 14-hydroxyclarithromycin is not considered to be clinically significant.

Side effectsView
The most frequently occurring adverse events reported with Esomeprazole include headache, diarrhoea, nausea, flatulence, abdominal pain, constipation and dry mouth. There are no difference in types of related adverse events seen during maintenance treatment upto 12 months compared to short term treatment.
ContraindicationsView
Esomeprazole is contraindicated in-patient with known hypersensitivity to any of the formulation.
PrecautionsView
General: Symptomatic response to therapy with esomeprazole does not preclude the presence of gastric malignancy.
Information for patients: Esomeprazole capsules should be taken at least one hour before meals. For patients who have difficulty swallowing capsules, one tablespoon of applesauce can be added to an empty bowl and the Esomeprazole capsules can be opened, and the pellets inside the capsule carefully emptied onto the applesauce. The pellets should be mixed with the applesauce and then swallowed immediately. The applesauce used should not be hot and should be soft enough to be swallowed without chewing. The pellets should not be chewed or crushed. The pellet/applesauce mixture should not be stored for future use. Antacids may be used while taking esomeprazole.

InteractionsView
Esomeprazole is extensively metabolized in the liver by CYP2C19 and CYP3A4. In vitro and in vivo studies have shown that Esomeprazole is not likely to inhibit CYPs 1A2, 2A6, 2C9, 2D6, 2E1 and 3A4. No clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Drug interaction studies have shown that Esomeprazole does not have any clinically significant interactions with phenytoin, warfarin, quinidine, clarithromycin or amoxicillin.
Esomeprazole may potentially interfere with CYP2C19, the major Esomeprazole metabolizing enzyme. Co-administration of Esomeprazole 30 mg and diazepam, a CYP2C19 substrate has resulted in a 45% decrease in clearance of diazepam. Increased plasma levels of diazepam have been observed 12 hours after dosing and onwards. Esomeprazole inhibits gastric acid secretion. Therefore, Esomeprazole may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (e.g., ketoconazole, iron salts and digoxin).
Co-administration of oral contraceptives, diazepam, phenytoin, or quinidine do not seem to change the pharmacokinetic profile of Esomeprazole.
Combination Therapy with Clarithromycin: Co-administration of esomeprazole, clarithromycin, and amoxicillin has resulted in increases in the plasma levels of esomeprazole and 14-hydroxyclarithromycin.

Pregnancy & lactationView
There are no adequate and well-controlled studies in pregnant women. Animal studies have revealed no teratogenic effects. The excretion of esomeprazole in milk has not been studied. Breast-feeding should be therefore be discontinued if the use of esomeprazole is considered essential.
Pediatric usageView
Paediatric Use: Safety and effectiveness in paediatric patients have not been established.
Geriatric Use: No overall differences in safety and efficacy have been observed between the elderly and younger individuals, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out
Hepatic Insufficiency: No dosage adjustment is recommended for patients with mild to moderate hepatic insufficiency. However, in patients with severe hepatic insufficiency, a dose of 20 mg once daily should not be exceeded.
Renal Insufficiency: The Pharmacokinetics of Esomeprazole in patients with renal impairment are not expected to be altered relative to healthy volunteers as less than 1% of Esomeprazole is excreted unchanged in the urine.

Overdose effectsView
A single oral dose of Esomeprazole at 510 mg/kg (about 103 times the human dose on a body surface area basis), has been lethal to rats. The major signs of acute toxicity are reduced motor activity, changes in respiratory frequency, tremor, ataxia, and intermittent clonic convulsions. There have been no reports of overdose with Esomeprazole. No specific antidote for Esomeprazole is known. Since Esomeprazole is extensively protein bound, it is not expected to be removed by dialysis. In the event of overdosage, treatment should be symptomatic and supportive. As with the management of any overdose, the possibility of multiple drug ingestion should be considered.
ReconstitutionView
Infusion: Reconstitute one sterile single-dose vial of Esomeprazole IV Injection with 5 ml of the solvent (WFI) provided and further diluting the resulting solution within 0.9% Sodium Chloride solution or 5% Dextrose solution to make a final volume of 50 ml. The resultant infusion should be given intravenously over a period of 10-30 minutes. Chemical and physical in-use stability has been demonstrated for 12 hours after reconstitution with 0.9% Sodium Chloride solution or for 6 hours after reconstitution with 5% Dextrose solution. From a microbial point of view, the product should be used immediately. Any unused portion should be discarded.

The reconstituted solution should not be used if it contains visible particulate.
Side effectsView
The most frequently occurring adverse events reported with Esomeprazole include headache, diarrhoea, nausea, flatulence, abdominal pain, constipation and dry mouth. There are no difference in types of related adverse events seen during maintenance treatment upto 12 months compared to short term treatment.
ContraindicationsView
Esomeprazole is contraindicated in-patient with known hypersensitivity to any of the formulation.
PrecautionsView
General: Symptomatic response to therapy with esomeprazole does not preclude the presence of gastric malignancy.
Information for patients: Esomeprazole capsules should be taken at least one hour before meals. For patients who have difficulty swallowing capsules, one tablespoon of applesauce can be added to an empty bowl and the Esomeprazole capsules can be opened, and the pellets inside the capsule carefully emptied onto the applesauce. The pellets should be mixed with the applesauce and then swallowed immediately. The applesauce used should not be hot and should be soft enough to be swallowed without chewing. The pellets should not be chewed or crushed. The pellet/applesauce mixture should not be stored for future use. Antacids may be used while taking esomeprazole.

InteractionsView
Esomeprazole is extensively metabolized in the liver by CYP2C19 and CYP3A4. In vitro and in vivo studies have shown that Esomeprazole is not likely to inhibit CYPs 1A2, 2A6, 2C9, 2D6, 2E1 and 3A4. No clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Drug interaction studies have shown that Esomeprazole does not have any clinically significant interactions with phenytoin, warfarin, quinidine, clarithromycin or amoxicillin.
Esomeprazole may potentially interfere with CYP2C19, the major Esomeprazole metabolizing enzyme. Co-administration of Esomeprazole 30 mg and diazepam, a CYP2C19 substrate has resulted in a 45% decrease in clearance of diazepam. Increased plasma levels of diazepam have been observed 12 hours after dosing and onwards. Esomeprazole inhibits gastric acid secretion. Therefore, Esomeprazole may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (e.g., ketoconazole, iron salts and digoxin).
Co-administration of oral contraceptives, diazepam, phenytoin, or quinidine do not seem to change the pharmacokinetic profile of Esomeprazole.
Combination Therapy with Clarithromycin: Co-administration of esomeprazole, clarithromycin, and amoxicillin has resulted in increases in the plasma levels of esomeprazole and 14-hydroxyclarithromycin.

Pregnancy & lactationView
There are no adequate and well-controlled studies in pregnant women. Animal studies have revealed no teratogenic effects. The excretion of esomeprazole in milk has not been studied. Breast-feeding should be therefore be discontinued if the use of esomeprazole is considered essential.
Pediatric usageView
Paediatric Use: Safety and effectiveness in paediatric patients have not been established.
Geriatric Use: No overall differences in safety and efficacy have been observed between the elderly and younger individuals, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out
Hepatic Insufficiency: No dosage adjustment is recommended for patients with mild to moderate hepatic insufficiency. However, in patients with severe hepatic insufficiency, a dose of 20 mg once daily should not be exceeded.
Renal Insufficiency: The Pharmacokinetics of Esomeprazole in patients with renal impairment are not expected to be altered relative to healthy volunteers as less than 1% of Esomeprazole is excreted unchanged in the urine.

Overdose effectsView
A single oral dose of Esomeprazole at 510 mg/kg (about 103 times the human dose on a body surface area basis), has been lethal to rats. The major signs of acute toxicity are reduced motor activity, changes in respiratory frequency, tremor, ataxia, and intermittent clonic convulsions. There have been no reports of overdose with Esomeprazole. No specific antidote for Esomeprazole is known. Since Esomeprazole is extensively protein bound, it is not expected to be removed by dialysis. In the event of overdosage, treatment should be symptomatic and supportive. As with the management of any overdose, the possibility of multiple drug ingestion should be considered.
ReconstitutionView
Infusion: Reconstitute one sterile single-dose vial of Esomeprazole IV Injection with 5 ml of the solvent (WFI) provided and further diluting the resulting solution within 0.9% Sodium Chloride solution or 5% Dextrose solution to make a final volume of 50 ml. The resultant infusion should be given intravenously over a period of 10-30 minutes. Chemical and physical in-use stability has been demonstrated for 12 hours after reconstitution with 0.9% Sodium Chloride solution or for 6 hours after reconstitution with 5% Dextrose solution. From a microbial point of view, the product should be used immediately. Any unused portion should be discarded.
StorageView
Store at a temperature not exceeding 30°C in a dry place. Protect from light and moisture. Keep out of reach of children.

Epleron
Eplerenone
Indications
Oedema
Indication detailsView
Congestive heart failure after an acute myocardial infarction, Hypertension.
Therapeutic classView
Potassium-sparing diuretics, Potassium-sparing diuretics & Aldosterone antagonists
PharmacologyView
Eplerenone selectively binds to the mineralocorticoid receptor and blocks the binding of aldosterone, a key component in the renin-angiotensin-aldosterone-system, which is involved in the regulation of BP and pathophysiology of CV disease. Aldosterone binds to mineralocorticoid receptors in both epithelial (e.g. kidney, GI tract) and nonepithelial (e.g. heart, blood vessels, brain) tissues; causing increases in BP by inducing Na reabsorption, vascular remodelling, water retention, endothelial dysfunction and possibly other mechanisms.
DosageView
Congestive Heart Failure after an acute Myocardial Infarction: The recommended dose of Eplerenone is 50 mg once daily. Treatment should be initiated at 25 mg once daily and titrated to the target dose of 50 mg once daily preferably within 4 weeks as tolerated by the patient. Eplerenone may be administered with or without food.
Hypertension: Eplerenone may be used alone or in combination with other antihypertensive agents. The recommended starting dose of Eplerenone is 50 mg administered once daily. For patients with an inadequate blood pressure response to 50 mg once daily the dosage of Eplerenone should be increased to 50 mg twice daily. Higher dosages of Eplerenone are not recommended either because they have no greater effect on blood pressure than 100 mg or because they are associated with an increased risk of hyperkalemia.

- Potassium-sparing diuretics are also contraindicated
PrecautionsView
Eplerenone should be used with caution in hyperkalemia, severe kidney disease, diabetic patients with congestive heart failure after an acute myocardial infarction including those with proteinuria.
InteractionsView
May increase risk of hyperkalaemia with ACE inhibitors and/or angiotension receptor blocker, ciclosporin, tacrolimus, trimethoprim. May reduce antihypertensive effect with NSAIDs, glucocorticoids, tetracosactide. May enhance hypotensive effect of α1-blockers (e.g. alfuzosin, prazosin), TCAs, amifostine, baclofen, neuroleptics. May increase plasma level with mild to moderate CYP3A4 inhibitors (e.g. fluconazole, erythromycin, saquinavir, amiodarone, diltiazem, verapamil).
Pregnancy & lactationView
Pregnancy: There are no adequate and well-controlled studies in pregnant women. Eplerenone should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Lactation: The concentration of Eplerenone in human breast milk after oral administration is unknown. Because many drugs are excreted in human milk and because of the unknown potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Zaleplon
Eplon
Zaleplon
Indications
Insomnia and sleep disturbances
Indication detailsView
Zaleplon is indicated for the short-term treatment of insomnia. Zaleplon has been shown to decrease the time to sleep onset for up to 30 days in controlled clinical trials.
Therapeutic classView
Benzodiazepine hypnotics, Benzodiazepine sedatives
PharmacologyView
Zaleplon is a newer non-benzodiazepine hypnotic from the pyrazolopyrimidine class. So, its chemical structure is unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties. It interacts with the gamma aminobutyric acid-benzodiazepine (GABA-BZ) receptor complex.
DosageView
The dose of Zaleplon should be individualized. The recommended dose of Zaleplon for most non elderly adults is 10 mg. For certain low weight individuals, 5 mg may be a sufficient dose. Although the risk of certain adverse events associated with the use of Zaleplon appears to be dose dependent, the 20 mg dose has been shown to be adequately tolerated and may be considered for occasional patient who does not benefit from a trial of lower dose. Dosage above 20 mg has not been adequately evaluated and is not recommended.
Zaleplon should be taken immediately before bedtime. Taking Zaleplon with or immediately after a heavy, high fat meal results in slower absorption and would be expected to reduce the effect of Zaleplon on sleep latency. Elderly patients and debilitated patients appear to be more sensitive to the effects of hypnotic, and respond to 5 mg of Zaleplon. The recommended dose for these patients is therefore 5 mg, doses over 10 mg are not recommended.
For patients with mild to moderate renal impairment, no dose adjustment is necessary.
An initial dose of 5 mg should be given to patients concomitantly taking Cimetidine because Zaleplon clearance is reduced in this population.
Pediatric use: The safety and effectiveness of Zaleplon in pediatric patients have not been established.

An initial dose of 5 mg should be given to patients concomitantly taking Cimetidine because Zaleplon clearance is reduced in this population.
Pediatric use: The safety and effectiveness of Zaleplon in pediatric patients have not been established.
Side effectsView
Side effects of Zaleplon appear to be dose related. So, it is important to use the lowest possible effective dose, specially in the elderly. The side effects are usually mild and transient, the most common are diarrhoea, nausea, vomiting, vertigo, headache, asthenia, nightmare etc.
ContraindicationsView
Zaleplon is contraindicated in patients with known hypersensitivity to any of its components.
PrecautionsView
Timing of drug administration: Zaleplon should be taken immediately before bedtime or after the patient has gone to bed.
Use in the elderly and/or debilitated patients: Impaired motor and/or cognitive performance after repeated exposure or unusual sensitivity to sedative/hypnotic drugs is a concern in the treatment of elderly and/or debilitated patients. A dose of 5 mg is recommended for elderly patients to decrease the possibility of side effects. Elderly and/or debilitated patients should be monitored closely.
Use in patients with concomitant illness: Zaleplon should be used with caution in patients with diseases or conditions that could affect metabolism or haemodynamic responses. Although preliminary studies did not reveal respiratory depressant effects at hypnotic doses of Zaleplon in normal subjects, caution should be observed if Zaleplon is prescribed to patients with compromised respiratory function, because sedative/hypnotic have the capacity to depress respiratory drive. However, patients with compromised respiration due to preexisting illness should be monitored carefully. The dose of Zaleplon should be reduced to 5 mg in patients with mild to moderate hepatic impairment. It is not recommended for use in patients with severe hepatic impairment.
Renal impairment patients: No dose adjustment is necessary in patients with mild to moderate renal impairment. Zaleplon has not been adequately studied in patients with severe renal impairment.
Use in patients with depression: As with other sedative or hypnotic drugs, Zaleplon should be administered with caution to patients exhibiting signs or symptoms of depression
Use in the elderly and/or debilitated patients: Impaired motor and/or cognitive performance after repeated exposure or unusual sensitivity to sedative/hypnotic drugs is a concern in the treatment of elderly and/or debilitated patients. A dose of 5 mg is recommended for elderly patients to decrease the possibility of side effects. Elderly and/or debilitated patients should be monitored closely.
Use in patients with concomitant illness: Zaleplon should be used with caution in patients with diseases or conditions that could affect metabolism or haemodynamic responses.

InteractionsView
Zaleplon has been shown to have minimal effects on the kinetic of Warfarin, Imipramine, Ethanol, Ibuprofen, Diphenhydramine, Thioridazine, and Digoxin.
Pregnancy & lactationView
Pregnancy: There are no studies of Zaleplon in pregnant women; therefore, it is not recommended for use in women during pregnancy. Zaleplon has no established use in labour and delivery.
Lactation: A study in lactating mothers indicated that the clearance and half-life of Zaleplon is similar to that in young normal subjects. A small amount of Zaleplon is excreted in breast milk, with the highest excreted amount occurring during a feeding at approximately 1 hour after Zaleplon administration. Since the small amount of the drug from breast milk may result in potentially important concentrations in infants, and because the effects of Zaleplon on a nursing infant are not known, it is not recommended in nursing mothers.

Indications
Insomnia and sleep disturbances
Indication detailsView
Zaleplon is indicated for the short-term treatment of insomnia. Zaleplon has been shown to decrease the time to sleep onset for up to 30 days in controlled clinical trials.
Therapeutic classView
Benzodiazepine hypnotics, Benzodiazepine sedatives
PharmacologyView
Zaleplon is a newer non-benzodiazepine hypnotic from the pyrazolopyrimidine class. So, its chemical structure is unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties. It interacts with the gamma aminobutyric acid-benzodiazepine (GABA-BZ) receptor complex.
DosageView
The dose of Zaleplon should be individualized. The recommended dose of Zaleplon for most non elderly adults is 10 mg. For certain low weight individuals, 5 mg may be a sufficient dose. Although the risk of certain adverse events associated with the use of Zaleplon appears to be dose dependent, the 20 mg dose has been shown to be adequately tolerated and may be considered for occasional patient who does not benefit from a trial of lower dose. Dosage above 20 mg has not been adequately evaluated and is not recommended.
Zaleplon should be taken immediately before bedtime. Taking Zaleplon with or immediately after a heavy, high fat meal results in slower absorption and would be expected to reduce the effect of Zaleplon on sleep latency. Elderly patients and debilitated patients appear to be more sensitive to the effects of hypnotic, and respond to 5 mg of Zaleplon. The recommended dose for these patients is therefore 5 mg, doses over 10 mg are not recommended.
For patients with mild to moderate renal impairment, no dose adjustment is necessary.
An initial dose of 5 mg should be given to patients concomitantly taking Cimetidine because Zaleplon clearance is reduced in this population.
Pediatric use: The safety and effectiveness of Zaleplon in pediatric patients have not been established.

Side effectsView
Side effects of Zaleplon appear to be dose related. So, it is important to use the lowest possible effective dose, specially in the elderly. The side effects are usually mild and transient, the most common are diarrhoea, nausea, vomiting, vertigo, headache, asthenia, nightmare etc.
ContraindicationsView
Zaleplon is contraindicated in patients with known hypersensitivity to any of its components.
PrecautionsView
Timing of drug administration: Zaleplon should be taken immediately before bedtime or after the patient has gone to bed.

Clonazepam
Indication detailsView
It is indicated for the treatment of panic disorder, with or without agoraphobia. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks.
It is also indicated alone or as an adjunct in the treatment of the Lennox-Gastaut Syndrome (petit mal variant), akinetic and myoclonic seizures. It may be indicated in patients with absence seizures (petit mal) who have failed to respond to succinimides.
The effectiveness of Clonazepam in long-term use, that is, for more than 9 weeks, has not been systematically studied in controlled clinical trials. The physician who elects to use Clonazepam for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

Therapeutic classView
Adjunct anti-epileptic drugs, Benzodiazepine hypnotics
PharmacologyView
Clonazepam exhibits pharmacological properties which are common to benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects. The central actions of benzodiazepines are mediated through an enhancement of the GABAergic neurotransmission at inhibitory synapses. In the presence of benzodiazepines the affinity of the GABA receptor for the neurotransmitter is enhanced through positive allosteric modulation resulting in an increased action of released GABA on the postsynaptic transmembrane chloride ion flux.
There are also animal data showing an effect of clonazepam on serotonin. Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absences seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations as well as irregular spikes and waves. Generalized EEG abnormalities are more regularly suppressed than focal abnormalities. According to these findings clonazepam has beneficial effects in generalized and focal epilepsies.

DosageView
Oral:
Injection:
- Adults: The initial dose for adults with seizure disorders should not exceed 1.5 mg/day divided into three doses. Dosage may be increased in increments of 0.5 to 1 mg every 3 days until seizures are adequately controlled or until side effects preclude any further increase. Maintenance dosage must be individualized for each patient depending upon response. Maximum recommended daily dose is 20 mg.
- The initial dose for adults with panic disorder is 0.25 mg given in two divided dose. An increase to the target dose for most patients of 1 mg/day may be made after 3 days.
- Pediatric Patients: In order to minimize drowsiness, the initial dose for infants and children (up to 10 years of age or 30 kg of body weight) should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in two or three divided doses.
Injection:
- Infants and children: half of a vial (0.5 mg) by slow IV injection or by IV infusion.
- Adults: 1 vial (1 mg) by slow IV injection or by IV infusion. This dose can be repeated as required (1-4 mg are usually sufficient to reverse the status). In adults, the rate of injection must not exceed 0.25 - 0.5 mg per minute (0.5-1.0 ml of the prepared solution) and a total dose of 10 mg should not be exceeded.
Side effectsView
The most frequently occurring side effects of Clonazepam are referable to CNS depression. Experience in treatment of seizures has shown that drowsiness has occurred in approximately 50% of patients and ataxia in approximately 30%. In some cases, these may diminish with time; behavior problems have been noted in approximately 25% of patients. Abnormal eye movements, aphonia, coma, tremor, vertigo, confusion, depression, amnesia, hallucinations, hysteria, increased libido, insomnia, psychosis & palpitations may also occur.
ContraindicationsView
It should not be used in patients with a history of hypersensitivity to benzodiazepines, nor in patients with clinical or biochemical evidence of significant liver disease. It may be used in patients with open angle glaucoma who are receiving appropriate therapy but is contraindicated in acute narrow angle glaucoma.
PrecautionsView
When used in patients in whom several different types of seizure disorders coexist, Clonazepam may increase the incidence or precipitate the onset of generalized tonic-clonic seizures. This may require the addition of appropriate anticonvulsants or an increase in their dosages. The concomitant use of valproic acid and Clonazepam may produce absence status.
InteractionsView
Clonazepam does not appear to alter the pharmacokinetics of phenytoin, carbamazepine or phenobarbital. The effect of Clonazepam on the metabolism of other drugs has not been investigated.
Pregnancy & lactationView
Pregnancy: From preclinical studies it cannot be excluded that clonazepam possesses the possibility of producing congenital malformations. From epidemiological evaluations there is evidence that anticonvulsant drugs act as teratogens. However, it is difficult to determine from published epidemiological reports which drug or combination of drugs is responsible for defects in the newborn. The possibility also exists that other factors e.g. genetic factors or the epileptic condition itself may be more important than drug therapy in leading to birth defects. Under these circumstances, the drug should only be administered to pregnant women if the potential benefits outweigh the risk to the foetus. During pregnancy, Clonazepam may be administered only if there is a compelling indication. Administration of high doses in the last trimester of pregnancy or during labour can cause irregularities in the heartbeat of the unborn child and hypothermia, hypotonia, mild respiratory depression and poor feeding in the neonate. It should be borne in mind that both pregnancy itself and abrupt discontinuation of the medication can cause exacerbation of epilepsy. Withdrawal symptoms in newborn infants have occasionally been reported with benzodiazepines.
Nursing Mothers: Although the active ingredient of Clonazepam has been found to pass into the maternal milk in small amounts only, mothers undergoing treatment with this drug should not breastfeed. If there is a compelling indication for Clonazepam, breastfeeding should be discontinued.

Pediatric usageView
Pediatric Use: In infants and small children Rivotril may cause increased production of saliva and bronchial secretion. Therefore special attention must be paid to maintaining patency of the airways.
Geriatric Use: Benzodiazepine pharmacologic effects appear to be greater in elderly patients than in younger patients even at similar plasma benzodiazepine concentrations, possibly because of age-related changes in drug–receptor interactions, post-receptor mechanisms and organ function.
Renal Impairment: Renal impairment does not affect the pharmacokinetics of clonazepam. Based on pharmacokinetic criteria, no dose adjustment is required in patients with renal impairment.
Hepatic Impairment: Plasma protein binding of clonazepam in cirrhotic patients is significantly different from that in healthy subjects (free fraction 17.1±1.0% vs 13.9±0.2%). Although the influence of hepatic impairment on clonazepam pharmacokinetics has not been further investigated, experience with another closely related nitrobenzodiazepine (nitrazepam) indicates that clearance of unbound clonazepam might be reduced in liver cirrhosis.

Overdose effectsView
Symptoms: Benzodiazepines commonly cause drowsiness, ataxia, dysarthria and nystagmus. Overdose of Clonazepam is seldom life-threatening if the drug is taken alone, but may lead to areflexia, apnoea, hypotension, cardiorespiratory depression and coma. Coma, if it occurs, usually lasts a few hours but it may be more protracted and cyclical, particularly in elderly patients. Increased frequency of seizures may occur in patients at supratherapeutic plasma concentrations. Benzodiazepine respiratory depressant effects are more serious in patients with respiratory disease. Benzodiazepines increase the effects of other central nervous system depressants, including alcohol.
Treatment: Monitor the patient’s vital signs and institute supportive measures as indicated by the patient’s clinical state. In particular, patients may require symptomatic treatment for cardiorespiratory effects or central nervous system effects. Further absorption should be prevented using an appropriate method e.g. treatment within 1-2 hours with activated charcoal. If activated charcoal is used airway protection is imperative for drowsy patients. In case of mixed ingestion gastric lavage may be considered, however not as a routine measure. If CNS depression is severe consider the use of flumazenil, a benzodiazepine antagonist. This should only be administered under closely monitored conditions. It has a short half-life (about an hour), therefore patients administered flumazenil will require monitoring after its effects have worn off. Flumazenil is to be used with extreme caution in the presence of drugs that reduce seizure threshold (e.g. tricyclic antidepressants). Refer to the prescribing information for flumazenil, for further information on the correct use of this drug.

ReconstitutionView
Slow intravenous injection: The contents of the vial must be diluted with 1 ml of water for injection prior to administration so as to avoid local irritation of the veins. The injection solution should be prepared immediately before use. IV injection should be administered slowly with continuous monitoring of EEG, respiration and blood pressure.
Intravenous infusion: Clonazepam (the vial) can be diluted for infusion in a ratio of 1 vial (1 mg) to at least 85 ml diluting media. The diluting media can be any of the following: sodium chloride 0.9%; sodium chloride 0.45% + glucose 2.5%; glucose 5% or glucose 10%. These mixtures are stable for 24 hours at room temperature. Infusion bags other than PVC should be used for infusing Clonazepam. If PVC infusion bags are used then the mixture should be infused immediately or within 4 hours. The infusion time should not exceed 8 hours. Do not prepare Clonazepam infusions using sodium bicarbonate solution, as precipitation of the solution may occur.
Intramuscular injection: The IM route should be used only in exceptional cases or if IV administration is not feasible.

If activated charcoal is used airway protection is imperative for drowsy patients. In case of mixed ingestion gastric lavage may be considered, however not as a routine measure. If CNS depression is severe consider the use of flumazenil, a benzodiazepine antagonist. This should only be administered under closely monitored conditions. It has a short half-life (about an hour), therefore patients administered flumazenil will require monitoring after its effects have worn off. Flumazenil is to be used with extreme caution in the presence of drugs that reduce seizure threshold (e.g. tricyclic antidepressants). Refer to the prescribing information for flumazenil, for further information on the correct use of this drug.
ReconstitutionView
Slow intravenous injection: The contents of the vial must be diluted with 1 ml of water for injection prior to administration so as to avoid local irritation of the veins. The injection solution should be prepared immediately before use. IV injection should be administered slowly with continuous monitoring of EEG, respiration and blood pressure.
Intravenous infusion: Clonazepam (the vial) can be diluted for infusion in a ratio of 1 vial (1 mg) to at least 85 ml diluting media. The diluting media can be any of the following: sodium chloride 0.9%; sodium chloride 0.45% + glucose 2.5%; glucose 5% or glucose 10%. These mixtures are stable for 24 hours at room temperature. Infusion bags other than PVC should be used for infusing Clonazepam. If PVC infusion bags are used then the mixture should be infused immediately or within 4 hours. The infusion time should not exceed 8 hours. Do not prepare Clonazepam infusions using sodium bicarbonate solution, as precipitation of the solution may occur.
Intramuscular injection: The IM route should be used only in exceptional cases or if IV administration is not feasible.

Indication detailsView
It is indicated for the treatment of panic disorder, with or without agoraphobia. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks.
It is also indicated alone or as an adjunct in the treatment of the Lennox-Gastaut Syndrome (petit mal variant), akinetic and myoclonic seizures. It may be indicated in patients with absence seizures (petit mal) who have failed to respond to succinimides.
The effectiveness of Clonazepam in long-term use, that is, for more than 9 weeks, has not been systematically studied in controlled clinical trials. The physician who elects to use Clonazepam for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

PharmacologyView
Clonazepam exhibits pharmacological properties which are common to benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects. The central actions of benzodiazepines are mediated through an enhancement of the GABAergic neurotransmission at inhibitory synapses. In the presence of benzodiazepines the affinity of the GABA receptor for the neurotransmitter is enhanced through positive allosteric modulation resulting in an increased action of released GABA on the postsynaptic transmembrane chloride ion flux.
There are also animal data showing an effect of clonazepam on serotonin. Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absences seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations as well as irregular spikes and waves. Generalized EEG abnormalities are more regularly suppressed than focal abnormalities. According to these findings clonazepam has beneficial effects in generalized and focal epilepsies.

DosageView
Oral:
Injection:
- Adults: The initial dose for adults with seizure disorders should not exceed 1.5 mg/day divided into three doses. Dosage may be increased in increments of 0.5 to 1 mg every 3 days until seizures are adequately controlled or until side effects preclude any further increase. Maintenance dosage must be individualized for each patient depending upon response. Maximum recommended daily dose is 20 mg.
- The initial dose for adults with panic disorder is 0.25 mg given in two divided dose. An increase to the target dose for most patients of 1 mg/day may be made after 3 days.
- Pediatric Patients: In order to minimize drowsiness, the initial dose for infants and children (up to 10 years of age or 30 kg of body weight) should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in two or three divided doses.
Injection:
- Infants and children: half of a vial (0.5 mg) by slow IV injection or by IV infusion.
- Adults: 1 vial (1 mg) by slow IV injection or by IV infusion. This dose can be repeated as required (1-4 mg are usually sufficient to reverse the status). In adults, the rate of injection must not exceed 0.25 - 0.5 mg per minute (0.5-1.0 ml of the prepared solution) and a total dose of 10 mg should not be exceeded.
Side effectsView
The most frequently occurring side effects of Clonazepam are referable to CNS depression. Experience in treatment of seizures has shown that drowsiness has occurred in approximately 50% of patients and ataxia in approximately 30%. In some cases, these may diminish with time; behavior problems have been noted in approximately 25% of patients. Abnormal eye movements, aphonia, coma, tremor, vertigo, confusion, depression, amnesia, hallucinations, hysteria, increased libido, insomnia, psychosis & palpitations may also occur.
ContraindicationsView
It should not be used in patients with a history of hypersensitivity to benzodiazepines, nor in patients with clinical or biochemical evidence of significant liver disease. It may be used in patients with open angle glaucoma who are receiving appropriate therapy but is contraindicated in acute narrow angle glaucoma.
PrecautionsView
When used in patients in whom several different types of seizure disorders coexist, Clonazepam may increase the incidence or precipitate the onset of generalized tonic-clonic seizures. This may require the addition of appropriate anticonvulsants or an increase in their dosages. The concomitant use of valproic acid and Clonazepam may produce absence status.
InteractionsView
Clonazepam does not appear to alter the pharmacokinetics of phenytoin, carbamazepine or phenobarbital. The effect of Clonazepam on the metabolism of other drugs has not been investigated.
Pregnancy & lactationView
Pregnancy: From preclinical studies it cannot be excluded that clonazepam possesses the possibility of producing congenital malformations. From epidemiological evaluations there is evidence that anticonvulsant drugs act as teratogens. However, it is difficult to determine from published epidemiological reports which drug or combination of drugs is responsible for defects in the newborn. The possibility also exists that other factors e.g. genetic factors or the epileptic condition itself may be more important than drug therapy in leading to birth defects. Under these circumstances, the drug should only be administered to pregnant women if the potential benefits outweigh the risk to the foetus. During pregnancy, Clonazepam may be administered only if there is a compelling indication. Administration of high doses in the last trimester of pregnancy or during labour can cause irregularities in the heartbeat of the unborn child and hypothermia, hypotonia, mild respiratory depression and poor feeding in the neonate. It should be borne in mind that both pregnancy itself and abrupt discontinuation of the medication can cause exacerbation of epilepsy. Withdrawal symptoms in newborn infants have occasionally been reported with benzodiazepines.
Nursing Mothers: Although the active ingredient of Clonazepam has been found to pass into the maternal milk in small amounts only, mothers undergoing treatment with this drug should not breastfeed. If there is a compelling indication for Clonazepam, breastfeeding should be discontinued.

Pediatric usageView
Pediatric Use: In infants and small children Rivotril may cause increased production of saliva and bronchial secretion. Therefore special attention must be paid to maintaining patency of the airways.
Geriatric Use: Benzodiazepine pharmacologic effects appear to be greater in elderly patients than in younger patients even at similar plasma benzodiazepine concentrations, possibly because of age-related changes in drug–receptor interactions, post-receptor mechanisms and organ function.
Renal Impairment: Renal impairment does not affect the pharmacokinetics of clonazepam. Based on pharmacokinetic criteria, no dose adjustment is required in patients with renal impairment.
Hepatic Impairment: Plasma protein binding of clonazepam in cirrhotic patients is significantly different from that in healthy subjects (free fraction 17.1±1.0% vs 13.9±0.2%). Although the influence of hepatic impairment on clonazepam pharmacokinetics has not been further investigated, experience with another closely related nitrobenzodiazepine (nitrazepam) indicates that clearance of unbound clonazepam might be reduced in liver cirrhosis.

Overdose effectsView
Symptoms: Benzodiazepines commonly cause drowsiness, ataxia, dysarthria and nystagmus. Overdose of Clonazepam is seldom life-threatening if the drug is taken alone, but may lead to areflexia, apnoea, hypotension, cardiorespiratory depression and coma. Coma, if it occurs, usually lasts a few hours but it may be more protracted and cyclical, particularly in elderly patients. Increased frequency of seizures may occur in patients at supratherapeutic plasma concentrations. Benzodiazepine respiratory depressant effects are more serious in patients with respiratory disease. Benzodiazepines increase the effects of other central nervous system depressants, including alcohol.
Treatment: Monitor the patient’s vital signs and institute supportive measures as indicated by the patient’s clinical state. In particular, patients may require symptomatic treatment for cardiorespiratory effects or central nervous system effects. Further absorption should be prevented using an appropriate method e.g. treatment within 1-2 hours with activated charcoal. If activated charcoal is used airway protection is imperative for drowsy patients. In case of mixed ingestion gastric lavage may be considered, however not as a routine measure. If CNS depression is severe consider the use of flumazenil, a benzodiazepine antagonist. This should only be administered under closely monitored conditions. It has a short half-life (about an hour), therefore patients administered flumazenil will require monitoring after its effects have worn off. Flumazenil is to be used with extreme caution in the presence of drugs that reduce seizure threshold (e.g. tricyclic antidepressants).

- Uncontrolled hypertension
- Known hypersensitivity to mammalian cell-derived products
- A history of hypersensitivity to Erythropoietin or any component of the preparation.
PrecautionsView
Erythropoietin should be used with caution in those patients with controlled hypertension, ischaemic vascular disease, history of seizures, or suspected allergy to the product.
Iron evaluation: Prior to and during Erythropoietin therapy, the patient's iron stores, including transferrin saturation and serum ferritin, should be evaluated. Transferrin saturation should be at least 20%, and ferritin should be at least 100 ng/ml. Virtually all patients will require supplemental Iron to increase or maintain transferrin saturation to levels that will adequately support erythropoiesis.

Pregnancy & lactationView
Pregnancy Category C. Since there are no controlled studies of erythropoietin in pregnant women, and because animal reproduction studies are not always predictive of human responses, erythropoietin should be used during pregnancy only if clearly needed. 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 erythropoietin is administered to a nursing woman.
Overdose effectsView
Doses of up to 1500 lU/kg TIW for 3 to 4 weeks have been administered to adults without any direct toxic effects. If the suggested target range is exceeded, drug therapy may be temporarily withheld until the hemoglobin returns to the suggested target range. If polycythemia is of concern, phlebotomy may be indicated to decrease the hemoglobin.
StorageView
Erythropoietin should be stored at 2°C to 8°C. Protect from light. Do not freeze & avoid shaking.

Indications
Increase yield of autologous blood
Indication detailsView
Erythropoietin is indicated for the treatment of-
- Anemia associated with Chronic Renal Failure, including patients on dialysis and patients not on dialysis.
- Anemia in patients with non-myeloid malignancies where anemia is due to the effect of concomitantly administered chemotherapy.
- Anemic patients (hemoglobin >10 to <13 g/dL) are scheduled to undergo elective, noncardiac, nonvascular surgery to reduce the need for allogeneic blood transfusions.
- Anemia related to therapy with zidovudine in HIV-infected patients.
Therapeutic classView
Drugs for Haemolytic Hypoplastic & Renal Anemia
DosageView
Treatment of anemia in chronic renal failure: Erythropoietin is administered to maintain hemoglobin concentration between 11 to 12 g/dl and hematocrit of 33-36 % in adults.
Starting dose:
Maintenance dose: Maintenance dose must be individualized for each patient. In patients undergoing dialysis, the median maintenance dose is 75 lU/kg TIW, with a range from 12.5 to 525 lU/kg TIW as directed by the physician. In CRF patients not on dialysis, maintenance dose is 75 to 150 lU/kg/week.
Treatment of Anemia in Cancer Patients on Chemotherapy:
Starting dose:
Surgery Patients: The recommended dose is 300 lU/kg/day subcutaneously for 10 days before surgery, on the day of surgery, and for 4 days after surgery. An alternate dose schedule is 600 lU/kg subcutaneously in once weekly dose (21, 14, and 7 days before surgery) plus a fourth dose on the day of surgery.
Zidovudine-treated HIV-infected Patients:
Starting dose
Maintenance dose: The dose is titrated to maintain the hematocrit between 33-36%.
Starting dose:
- Adult: Usually 50 to 100 lU/kg three times in a week (TIW) by IV or Subcutaneous route.
- Pediatric: 50 lU/kg TIW by IV or Subcutaneous route.
Maintenance dose: Maintenance dose must be individualized for each patient. In patients undergoing dialysis, the median maintenance dose is 75 lU/kg TIW, with a range from 12.5 to 525 lU/kg TIW as directed by the physician. In CRF patients not on dialysis, maintenance dose is 75 to 150 lU/kg/week.
Treatment of Anemia in Cancer Patients on Chemotherapy:
Starting dose:
- Adult: 150 lU/kg TIW by Subcutaneous route or 40,000 IU Subcutaneous route weekly.
- Pediatric: 25 to 300 lU/kg 3 to 7 times per week by Subcutaneous or IV route.
Surgery Patients: The recommended dose is 300 lU/kg/day subcutaneously for 10 days before surgery, on the day of surgery, and for 4 days after surgery. An alternate dose schedule is 600 lU/kg subcutaneously in once weekly dose (21, 14, and 7 days before surgery) plus a fourth dose on the day of surgery.
Zidovudine-treated HIV-infected Patients:
Starting dose
- Adult: 100 lU/kg as an IV or Subcutaneous injection TIW for 8 weeks.
- Pediatric: 50 to 400 lU/kg 2 to 3 times per week by Subcutaneous or IV route.
Maintenance dose: The dose is titrated to maintain the hematocrit between 33-36%.
AdministrationView
- Do not shake. It is not necessary to shake Erythropoietin. Prolonged vigorous shaking may denature any glycoprotein, rendering it biologically inactive.
- Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration.
- Administer as an intravenous injection over 1-2 minutes. In patients on dialysis, the injection should follow the dialysis procedure. Slow injection over 5 minutes may be beneficial to those who experience flu-like symptoms.
- Do not administer by intravenous infusion or in conjunction with other drug solutions.
- For the subcutaneous route, a maximum of 1 ml_ at one injection site should generally not be exceeded. In the case of larger volumes, more than one site should be chosen for the injection.
Side effectsView
General: Headache, dizziness, fever, malaise, arthralgia and occasionally hyperkalemia. Cardiovascular: Hypertension is the most common side effect, palpitations. Gastrointestinal: Nausea, vomiting, anorexia and diarrhea may occur occasionally. Allergic reactions.
