MonoSol Rx Inc. announced that the U.S. Food and Drug Administration (FDA) has accepted its Investigational New Drug (IND) Application for Riluzole Oral Soluble Film (Riluzole OSF) for the treatment of Amyotrophic Lateral Sclerosis. The accepted IND outlines MonoSol Rx’s clinical development plans for Riluzole OSF for the treatment of ALS. Riluzole is a glutamine blocker currently available in a tablet formulation.

Its use has also been studied in mood and anxiety disorders as well as Alzheimer’s Disease.
