Xanax is the brand name for alprazolam, a prescription medication in the benzodiazepine class. It is commonly prescribed to manage anxiety disorders, including generalized anxiety disorder (GAD) and panic disorders. Xanax is used primarily to treat anxiety disorders and panic attacks. It can help reduce symptoms such as excessive worry, agitation, and panic attacks by calming the central nervous system. Alprazolam works by enhancing the effects of the neurotransmitter GABA (gamma-aminobutyric acid) in the brain, which produces a calming effect. This helps alleviate symptoms of anxiety and panic.
