Xanax, generically known as Alprazolam, is a potent benzodiazepine prescribed to manage anxiety and panic disorders. It works by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain, producing a calming effect. Given its efficacy, many seek the convenience of purchasing Xanax online. Ensure the pharmacy is licensed and verified by relevant authorities. Look for certification from the National Association of Boards of Pharmacy (NABP) or similar regulatory bodies.
