What is Radicava?

Radicava is used to treat adults with amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease; a condition in which the nerves that control muscle movement slowly die, causing the muscles to shrink and weaken).

Radicava belongs to a class of medications called antioxidants. Edaravone works by relieving the effects of oxidative stress, which may be related to the death of motor neurons (nerve cells) in people with amyotrophic lateral sclerosis (ALS). Keeping motor neurons healthy may help to preserve muscle function.

Radicava is an injection that is given by intravenous infusion over 60 minutes. Radicava ORS is an oral suspension that is taken orally by mouth, or via a feeding tube.
