Pyrithyldione (Presidon, Persedon) is a psychoactive drug invented in 1949.[1] An improved method of manufacture was patented by Roche in 1959.[2] It was used as a hypnotic or sedative and presumed to be less toxic than barbiturates.[3] Today, this substance is no longer used. Agranulocytosis was sometimes reported as adverse effect.[4][5]
