Flualprazolam is a benzodiazepine derivative which was first synthesised in 1976 but was never marketed. It has subsequently been sold as a designer drug, first being definitively identified in Sweden in 2018. It can be described as the 2′-fluoro derivative of alprazolam, or the fluoro instead of chloro analogue of triazolam, and has similar sedative and anxiolytic effects.
