Alprazolam 1mg, commonly known by brand names such as Xanax and Ksalol, is a prescription medication widely used in the United States for the management of anxiety and panic disorders. As a benzodiazepine, it works by enhancing the effects of neurotransmitters that help calm the nervous system. Because of its potency and risk of dependence, Alprazolam is classified as a Schedule IV controlled substance and must be prescribed by a licensed healthcare provider.
