Adinazolam[1] (marketed under the brand name Deracyn) is a benzodiazepine derivative, and more specifically, a triazolobenzodiazepine (TBZD). It possesses anxiolytic, anticonvulsant, sedative, and antidepressant[2] properties. Adinazolam was developed by Dr. Jackson B. Hester, who was seeking to enhance the antidepressant properties of alprazolam, which he also developed.[3] Adinazolam was never FDA approved and never made available to the public market.
