Xanax 1mg refers to a specific dosage of the medication alprazolam, which is a benzodiazepine commonly prescribed to treat anxiety disorders, panic disorders, and occasionally insomnia. Xanax 1mg is primarily used to manage symptoms of generalized anxiety disorder (GAD), social anxiety disorder, and other anxiety disorders. Alprazolam, the active ingredient in Xanax, works by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter that helps reduce the activity of nerve cells in the brain, resulting in a calming effect on the central nervous system.
