Metabolite Identification
Common NameEthinamate
DescriptionEthinamate is a short-acting sedative-hypnotic medication used to treat insomnia. Regular use leads to tolerance, and it is usually not effective for more than 7 days. Structurally, it does not resemble the barbituates, but it shares many effects with this class of drugs; the depressant effects of ethinamate are, however, generally milder than those of most barbiturates.
