desethylzaleplon

Description

desethylzaleplon is a metabolite of zaleplon. Zaleplon (marketed under the brand names Sonata and Starnoc) is a sedative/hypnotic, mainly used for insomnia. It is a nonbenzodiazepine hypnotic from the pyrazolopyrimidine class. In terms of adverse effects zaleplon appears to offer little improvement compared to both benzodiazepines and other non-benzodiazepine Z-drugs. Sonata (US) is manufactured by King Pharm. of Bristol, TN; Starnoc has been discontinued in Canada. (Wikipedia)
