Xanax (generic name: alprazolam) is a medication in the benzodiazepine class used primarily for its anxiolytic (anxiety-reducing) effects. Xanax works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits nerve activity in the brain. This produces calming effects, which help to reduce anxiety and panic symptoms. Xanax is prescribed to manage symptoms of anxiety disorders, including generalized anxiety disorder (GAD). It is also used for the short-term treatment of panic disorder with or without agoraphobia.
