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