Xanax is a brand name for the prescription medication alprazolam. It is classified as a benzodiazepine, which is a class of drugs known for their calming and sedative effects on the central nervous system. Xanax is primarily prescribed to treat anxiety disorders, panic disorders, and sometimes used for short-term relief of anxiety symptoms.

The main action of Xanax is to enhance the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA helps to inhibit excessive brain activity, resulting in a calming and relaxing effect.

Xanax is typically taken orally in tablet form and is available in immediate-release and extended-release formulations. It is important to take Xanax exactly as prescribed by a healthcare professional, following the recommended dosage and schedule.
