Flualprazolam is a tranquilizer of the triazolobenzodiazepine class, which are benzodiazepines fused with a triazole ring. It was first synthesised in 1976, but was never marketed. It has subsequently been sold as a designer drug, first being definitively identified as such in Sweden

It can be described as the 2′-fluoro derivative of alprazolam, the fluoro instead of chloro analogue of triazolam, or the triazole analogue of flurazepam, and has similar sedative and anxiolytic effects
