Xanax, the brand name for alprazolam, is a prescription medication that belongs to the benzodiazepine class of drugs. It is commonly prescribed to manage anxiety disorders, panic disorders, and generalized anxiety disorder (GAD) by enhancing the effects of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA), which produces a calming effect on the nervous system. This helps reduce feelings of nervousness, restlessness, and sudden episodes of intense fear or panic. While Xanax can be highly effective when taken as directed, it also carries risks of dependence, tolerance, and withdrawal symptoms if misused or used long-term.
