There are currently four drugs approved by the U.S. Food and Drug Administration to treat ALS (Radicava, Rilutek, Tiglutik, and Nuedexta). Studies all over the world, many funded by The ALS Association, are ongoing to develop more treatments and a cure for ALS.
The FDA approved Radicava™ in 2017, less than a year after Mitsubishi Tanabe Pharma America submitted a new drug application, making it the first new treatment specifically for ALS in 22 years. Learn more.
Rilutek (riluzole, now generic)
This was the first FDA-approved drug available to treat ALS — in 1995. It inhibits glutamate release and prolongs life approximately three months. Riluzole is the generic name of Rilutek.
Tiglutik (thickened riluzole)
The first and only thickened liquid form of riluzole, Tiglutik was approved by the FDA in September 2018. This formulation contrasts with the oral pill form of riluzole that has been on the market for ALS for more than 20 years. It is designed to avoid potential problems of crushing tablets. Learn more.
Indicated for the treatment of pseudobulbar affect (PBA), which is characterized by frequent, involuntary, and often sudden episodes of crying and/or laughing that are exaggerated and/or don’t match how you feel. PBA occurs secondary to a variety of otherwise unrelated neurologic conditions. Nuedexta® (dextromethorphan HBr and quinidine sulfate) was FDA-approved in 2011.
