Flubromazépam

Flubromazepam is a long-lasting benzodiazepine that produces anxiolytic, sedative, muscle relaxant, and amnesic effects. Originally synthesized in 1960, it was never marketed and received no further attention until it resurfaced in late 2012 as an online research chemical. It has not been formally studied, meaning its pharmacological profile remains largely speculative, based on its subjective effects and structural similarities to other benzodiazepines.
