About EXSERVAN (riluzole oral film)
EXSERVAN, an oral film formulation of riluzole, was developed by Aquestive using its PharmFilm® innovative drug delivery technology. The oral film is placed on the patient’s tongue and quickly dissolves without the need for liquids or food. RILUTEK® (riluzole) tablets was the reference product during the oral film development. Oral film riluzole was approved by the U.S. Food and Drug Administration (FDA) in November 2019.

EXSERVAN™ (riluzole) is indicated for the treatment of amyotrophic lateral sclerosis (ALS).
