Xanax 1 mg (alprazolam) is a well-known prescription medication used primarily to treat anxiety and panic disorders. It belongs to a class of drugs called benzodiazepines, which act on the brain and central nervous system to produce a calming effect. By enhancing the action of a natural chemical in the brain called GABA, Xanax helps to reduce excessive nerve activity, making it effective for those struggling with intense anxiety or panic attacks.
