At a glance
Riluzole is a glutamate inhibitor used to slow disease progression and prolong survival in patients with amyotrophic lateral sclerosis (ALS). It inhibits glutamate release, inactivates voltage-dependent Na channels, and interferes with intracellular events following transmitter binding at excitatory amino acid receptors.
Indications
- Amyotrophic lateral sclerosis (ALS) - to extend life or delay time to mechanical ventilation
Pharmacology
Riluzole inhibits glutamate release, inactivates voltage-dependent Na channels, and interferes with intracellular events following transmitter binding at excitatory amino acid receptors. It is neuroprotective and exhibits anticonvulsant and myorelaxant properties in animal models.
Dosage

- ALS: 50 mg twice daily
- Take at least 1 hour before or 2 hours after meals
- Discontinue if ALT levels increase to 5 times ULN
