Alprazolam is a benzodiazepine medication primarily used to treat anxiety disorders such as generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder. It works by enhancing the effects of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain. By increasing GABA activity, alprazolam reduces anxiety and promotes relaxation. It was developed by Upjohn in the 1970s and was approved for medical use in the United States in 1981 under the brand name Xanax.

Mechanism of Action

Like other benzodiazepines, Alprazolam Tablets works by binding to benzodiazepine receptors on GABA-A receptors in the brain. This allows GABA to work more effectively at inhibiting neuronal activity. The precise mechanism by which alprazolam alleviates anxiety is not fully understood, but it may involve the facilitation of GABAergic neurotransmission in the limbic system of the brain, which is involved in fear and anxiety responses. When GABA activity in this area is increased, it leads to depressant, anti-convulsant, muscle relaxant, and anxiolytic effects that help reduce anxiety symptoms.

Indications for Use

Alprazolam tablets are approved by the U.S. Food and Drug Administration (FDA) for the following indications:

- Generalized anxiety disorder (GAD): Alprazolam is effective at treating the physical symptoms of anxiety such as restlessness, tension, palpitations, and feelings of apprehension or worry associated with GAD.
