What is Xanax? How does it work (mechanism of action)?

Alprazolam (Xanax XR, Niravam), is an anti-anxiety medication in the benzodiazepine drug family, the same family that includes diazepam (Valium), clonazepam (Klonopin), lorazepam (Ativan), flurazepam (Dalmane), and others. Alprazolam and other benzodiazepines act by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter (a chemical that nerve cells use to communicate with each other) that inhibits activity in the brain. It is believed that excessive activity in the brain may cause anxiety or other psychiatric disorders. The FDA approved alprazolam in October 1981.
