Fasiplon (RU 33203) is a nonbenzodiazepine anxiolytic drug from the imidazopyrimidine family of drugs.

Fasiplon binds strongly to benzodiazepine sites on the GABA_A receptor and has similar anxiolytic effects in animals, but with less sedative or muscle relaxant action.^[1] It was developed by a team at Roussel Uclaf in the 1990s^[2]
