Methylpentynol
Chemical compound
Methylpentynol (Methylparafynol, Dormison, Atemorin, Oblivon) is a tertiary pentynol with hypnotic/sedative and anticonvulsant effects and an exceptionally low therapeutic index. It was discovered by Bayer in 1913[2] and was used shortly thereafter for the treatment of insomnia, but its use was quickly phased out in response to newer drugs with far more favorable safety profiles.[3][4][5]
The drug was marketed again in the United States, Europe and elsewhere from 1956 well into the 1960s as a rapid-acting sedative.[6] The drug was quickly overshadowed at that point by benzodiazepines and is no longer sold anywhere.[7]
