Alprazolam, like other benzodiazepines, binds to specific sites on the GABA_A gamma-amino-butyric acid receptor. Alprazolam is commonly used and FDA approved for the medical treatment of panic disorder, and anxiety disorders, such as generalized anxiety disorder (GAD) or social anxiety disorder (SAD). Alprazolam is available for oral administration in compressed tablet (CT) and extended-release capsule (XR) formulations. Alprazolam possesses anxiolytic, sedative, hypnotic, skeletal muscle relaxant, anticonvulsant, and amnestic properties.

Alprazolam has a fast onset of action and symptomatic relief. 90% of peak benefits are achieved within the first hour of using either preparation for panic disorder, and full peak benefits are achieved in 1.5 and 1.6 hours respectively. Peak benefits achieved for generalized anxiety disorder (GAD) may take up to a week.Tolerance does not appear to develop to the anxiolytic effects but may develop to the sedative effects within a couple of days.Withdrawal symptoms or rebound symptoms may occur after ceasing treatment abruptly following a few weeks or longer of steady dosing, and may necessitate a gradual dose reduction.
