Alprazolam ( /ælˈpræzəˌlæm/; trade name Xanax, ) is a potent short-acting drug of the benzodiazepine class. Alprazolam, like other benzodiazepines, binds to specific sites on the GABAA gamma-amino-butyric acid receptor. It is primarily used to treat moderate to severe anxiety disorders (e.g., social anxiety disorder) and panic attacks. It is available in an immediate-release and an extended-release (Xanax XR) preparation, both of which are available under several generic names. Alprazolam possesses anxiolytic, sedative, hypnotic, skeletal muscle relaxant, anticonvulsant, and amnestic properties.
