Description
Curator's Comment:: https://www.ncbi.nlm.nih.gov/pubmed/8813989

Riluzole, a member of the benzothiazole class, is indicated for the treatment of patients with amyotrophic lateral sclerosis. 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. Common adverse reactions include headache, abdominal pain, back pain, vomiting, dyspepsia, diarrhea, dizziness. Riluzole-treated patients that take other hepatotoxic drugs may be at increased risk for hepatotoxicity.

Comment: Potential inhibitors of CYP1A2 (e.g. caffeine, phenacetin, theophylline, amitriphtyline, and quinolones) could decrease the rate of riluzole elimination, while inducers of CYP1A2 (e.g. cigarette smoke, charcoal-broiled food, rifampicin, and omeprazole) could increase rate of riluzole elimination

Sample Use Guides

50 mg twice daily, taken at least 1 hour before or 2
Route of Administration: Oral
In Vitro Use Guide
In vitro incubation of [14C]riluzole (15 microM) with human hepatic microsomes and NADPH or UDPGA cofactors resulted in formation of N-hydroxyriluzole (K(m) = 30 microM) or an unidentified glucuroconjugate (K(m) = 118 microM). Human microsomal riluzole N-hydroxylation was most strongly inhibited by the CYP1A2 inhibitor alpha-naphthoflavone (IC50 = 0.42 microM). Thus, riluzole is predominantly metabolized by CYP1A2 in human hepatic microsomes to N-hydroxyriluzole.
