Metabolite Identification
Common Name4-hydroxymidazolam
Description4-hydroxymidazolam is a metabolite of midazolam. Midazolam (marketed in English-speaking countries under the trade names Dormicum, Hypnovel, and Versed, is a short-acting drug in the benzodiazepine class developed by Hoffmann-La Roche in the 1970s. The drug is used for treatment of acute seizures, moderate to severe insomnia, and for inducing sedation and amnesia before medical procedures. It possesses profoundly potent anxiolytic, amnestic, hypnotic, anticonvulsant, skeletal muscle relaxant, and sedative properties. (Wikipedia)
