Riluzolo Zentiva
Riluzolo Zentiva Uses, Dosage, Side Effects, Food Interaction and all others data.
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.Riluzolo Zentiva, a member of the benzothiazole class, is indicated for the treatment of patients with amyotrophic lateral sclerosis (ALS). Riluzolo Zentiva extends survival and/or time to tracheostomy. It is also neuroprotective in various in vivo experimental models of neuronal injury involving excitotoxic mechanisms. The etiology and pathogenesis of amyotrophic lateral sclerosis (ALS) are not known, although a number of hypotheses have been advanced. One hypothesis is that motor neurons, made vulnerable through either genetic predisposition or environmental factors, are injured by glutamate. In some cases of familial ALS the enzyme superoxide dismutase has been found to be defective.

How Riluzolo Zentiva works
The mode of action of riluzole is unknown. Its pharmacological properties include the following, some of which may be related to its effect: 1) an inhibitory effect on glutamate release (activation of glutamate reuptake), 2) inactivation of voltage-dependent sodium channels, and 3) ability to interfere with intracellular events that follow transmitter binding at excitatory amino acid receptors.
Dosage
Riluzolo Zentiva dosage
The recommended dosage for Riluzolo Zentiva is 50 mg taken orally twice daily. Riluzolo Zentiva should be taken at least 1 hour before or 2 hours after a meal.Measure serum aminotransferases before and during treatment with Riluzolo Zentiva
Side Effects
The following adverse reactions are described below and elsewhere in the labeling: Hepatic Injury, Neutropenia, Interstitial lung disease
Precaution
Hepatic Injury: Cases of drug-induced liver injury, some of which were fatal, have been reported in patients taking Riluzolo Zentiva. Asymptomatic elevations of hepatic transaminases have also been reported, and in some patients have recurred upon rechallenge with Riluzolo Zentiva.
In clinical studies, the incidence of elevations in hepatic transaminases was greater in Riluzolo Zentivatreated patients than placebo-treated patients. The incidence of elevations of ALT above 5 times the upper limit of normal (ULN) was 2% in Riluzolo Zentiva-treated patients. Maximum increases in ALT occurred within 3 months after starting Riluzolo Zentiva. About 50% and 8% of Riluzolo Zentivatreated 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 Riluzolo Zentiva is not recommended if patients develop hepatic transaminases levels greater than 5 times the ULN. Discontinue Riluzolo Zentiva 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 Riluzolo Zentiva treatment have been reported. Advise patients to report febrile illnesses.
Interstitial Lung Disease: Interstitial lung disease, including hypersensitivity pneumonitis, has occurred in patients taking Riluzolo Zentiva. Discontinue Riluzolo Zentiva immediately if interstitial lung disease develops.
Interaction
Strong to moderate CYP1A2 inhibitors: Coadministration may increase Riluzolo Zentiva-associated adverse reactions
Strong to moderate CYP1A2 inducers: Coadministration may result in decreased efficacy
Hepatotoxic drugs: Riluzolo Zentiva-treated patients that take other hepatotoxic drugs may be at increased risk for hepatotoxicity
Food Interaction
- Take on an empty stomach. Take at least 1 hour before or 2 hours after meals.
Riluzolo Zentiva Drug Interaction
Unknown: amphetamine / dextroamphetamine, lorazepam, diphenhydramine, heparin, clonazepam, escitalopram, lithium, mirabegron, dextromethorphan / quinidine, acetaminophen / oxycodone, vitamin a topical, bioflavonoids, levothyroxine, acetaminophen, cyanocobalamin, ascorbic acid, cholecalciferol, alprazolam, ranitidine, sertraline
Riluzolo Zentiva Disease Interaction
Moderate: alcohol, liver disease, neutropenia, renal dysfunction
Elimination Route
Riluzolo Zentiva is well-absorbed (approximately 90%), with average absolute oral bioavailability of about 60% (CV=30%). A high fat meal decreases absorption, reducing AUC by about 20% and peak blood levels by about 45%.
Half Life
The mean elimination half-life of riluzole is 12 hours (CV=35%) after repeated doses.
Pregnancy & Breastfeeding use
Pregnancy: Based on animal data, may cause fetal harm
Lactation: It is not known if riluzole is excreted in human milk. Riluzolo Zentiva 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 Riluzolo Zentiva is unknown.
Contraindication
Riluzolo Zentiva is contraindicated in patients with a history of severe hypersensitivity reactions to riluzole or to any of its components (anaphylaxis has occurred)
Acute Overdose
Reported symptoms of overdose following ingestion of Riluzolo Zentiva 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 Riluzolo Zentiva overdose is available.
Storage Condition
Store at controlled room temperature, 20°C to 25°C, and protect from bright light.
