N-Desalkylflurazepam (also known as norflurazepam) is a benzodiazepine analog and an active metabolite of several other benzodiazepine drugs including flurazepam,[2] flutoprazepam,[3] fludiazepam,[4] midazolam,[5] flutazolam,[6] quazepam,[7] and ethyl loflazepate.[8][9] It is long-acting, prone to accumulation, and binds unselectively to the various benzodiazepine receptor subtypes.[7] It has been sold as a designer drug from 2016 onward.[10]
