Alprazolam, also known by its brand name Xanax, is a prescription medication that belongs to a class of drugs called benzodiazepines. It is primarily used to treat anxiety and panic disorders.

Alprazolam works by enhancing the activity of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA), which has a calming effect on the nervous system. This can help to reduce anxiety and panic symptoms, such as excessive worry, restlessness, and racing thoughts.
