Clinical Pharmacology

The mechanism by which riluzole exerts its therapeutic effects in patients with ALS is unknown.

Non-Clinical Toxicology
RILUTEK is contraindicated in patients with a history of severe hypersensitivity reactions to riluzole or to any of its components (anaphylaxis has occurred) .

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

In clinical studies, the incidence of elevations in hepatic transaminases was greater in RILUTEK-treated patients than placebo-treated patients. The incidence of elevations of ALT above 5 times the upper limit of normal (ULN) was 2% in RILUTEK-treated patients. Maximum increases in ALT occurred within 3 months after starting RILUTEK. About 50% and 8% of RILUTEK-treated 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 RILUTEK is not recommended if patients develop hepatic transaminase levels greater than 5 times the ULN. Discontinue RILUTEK if there is evidence of liver dysfunction (e.g., elevated bilirubin).
