N-Desalkylflurazepam is an active metabolite of several benzodiazepine drugs including flurazepam,[2] flutoprazepam,[3] fludiazepam,[4] midazolam,[5] quazepam,[6] and ethyl loflazepate.[7][8] It is long-acting, prone to accumulation, and binds unselectively to the various benzodiazepine receptor subtypes.[6]
