Bromazolam (XLI-268) is a triazolobenzodiazepine (TBZD) which was first synthesised in 1976, but was never marketed.[2] It has subsequently been sold as a designer drug, first being definitively identified by the EMCDDA in Sweden in 2016.[3] It is the bromo instead of chloro analogue of alprazolam and has similar sedative and anxiolytic effects to it and other benzodiazepines.[4][5] Bromazolam is a non subtype selective agonist at the benzodiazepine site of GABAA receptors, with a binding affinity of 2.81 nM at the α1 subtype, 0.69 nM at α2 and 0.62 nM at α5.[6] The "common" dosage range for users of bromazolam was reported to be 1–2 mg, suggesting its potency is similar to alprazolam.[7]
