Alprazolam, commonly known by its brand name Xanax, is a prescription medication used to treat anxiety disorders, panic disorders, and sometimes insomnia. It belongs to the benzodiazepine class, which works by enhancing the calming effects of GABA in the brain. This leads to reduced anxiety, muscle relaxation, and sedation. Due to its potential for dependence and withdrawal symptoms, Alprazolam is usually prescribed for short-term use under medical supervision.
