Xanax, also known by its generic name alprazolam, is a prescription medication belonging to the benzodiazepine class. It is primarily used to treat anxiety disorders, panic disorders, and anxiety caused by depression. Xanax works by enhancing the activity of certain neurotransmitters in the brain, particularly gamma-aminobutyric acid (GABA). This leads to a calming effect on the central nervous system, helping to reduce symptoms of anxiety and panic. less
