Riluzole is used in the treatment of amyotrophic lateral sclerosis (ALS).
How Riluzole works Riluzole is a glutamate antagonist and is used as an anticonvulsant. It is believed to work by inhibiting the action of glutamate, a chemical messenger, and also inactivates voltage-dependent sodium channels. In this way, it regulates the transmission of nerve signals in the brain.
Common side effects of Riluzole include weakness, dizziness, nausea, decreased pulmonary function, high blood pressure, tachycardia, xerostomia, and peripheral edema.
