Xanax is the brand name for alprazolam, a medication in the benzodiazepine class. It is commonly prescribed to manage anxiety disorders, panic disorders, and sometimes for short-term relief of symptoms associated with anxiety. Xanax is used to treat generalized anxiety disorder (GAD) and other anxiety-related conditions. It is also prescribed to manage panic attacks, including those associated with panic disorder. Alprazolam works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity. This calming effect helps reduce anxiety and panic symptoms.
