Pyrithyldione[1] (Presidon, Persedon) is a psychoactive drug invented in 1949.[2] An improved method of manufacture was patented by Roche in 1959.[3] It was used as a hypnotic or sedative and presumed to be less toxic than barbiturates.[4] Today, this substance is no longer used. Agranulocytosis was sometimes reported as adverse effect.[5][6] Pyrithyldione is also a CYP2D6 inducer but is not as potent as glutethimide[7] In studies, it increased the O-Demethylation of codeine by 20%.
