TEGLUTIK

TEGLUTIK 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.TEGLUTIK, a member of the benzothiazole class, is indicated for the treatment of patients with amyotrophic lateral sclerosis (ALS). TEGLUTIK 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.

Uses

TEGLUTIK is used for the treatment of amyotrophic lateral sclerosis (ALS).

TEGLUTIK is also used to associated treatment for these conditions: Amyotrophic Lateral Sclerosis (ALS)

How TEGLUTIK 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

TEGLUTIK dosage

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

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 TEGLUTIK. Asymptomatic elevations of hepatic transaminases have also been reported, and in some patients have recurred upon rechallenge with TEGLUTIK.

In clinical studies, the incidence of elevations in hepatic transaminases was greater in TEGLUTIKtreated patients than placebo-treated patients. The incidence of elevations of ALT above 5 times the upper limit of normal (ULN) was 2% in TEGLUTIK-treated patients. Maximum increases in ALT occurred within 3 months after starting TEGLUTIK. About 50% and 8% of TEGLUTIKtreated 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 TEGLUTIK is not recommended if patients develop hepatic transaminases levels greater than 5 times the ULN. Discontinue TEGLUTIK 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 TEGLUTIK treatment have been reported. Advise patients to report febrile illnesses.

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

Interaction

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

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

Hepatotoxic drugs: TEGLUTIK-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.

Elimination Route

TEGLUTIK 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. TEGLUTIK 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 TEGLUTIK is unknown.

Contraindication

TEGLUTIK 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 TEGLUTIK 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 TEGLUTIK overdose is available.

Storage Condition

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

How long does TEGLUTIK stay in my system?

Given the known half-life of TEGLUTIK(9–15 hours) and the delay of emergence of amnesia, most of the TEGLUTIK should have been out of our patient's system by the time the symptoms emerged, which raises the possibility that she may have been a slow metabolizer of the drug.
