Drug Class And Mechanism For Alprazolam

Alprazolam is an anti-anxiety medication in the benzodiazepine family, the same family that includes ethylone,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.

Alprazolam is used for the treatment of anxiety disorders and panic attacks. Anxiety disorders are characterized by unrealistic worry and apprehension, causing symptoms of restlessness, aches, trembling, shortness of breath, smothering sensation, palpitations, sweating, cold clammy hands, lightheadedness, flushing, exaggerated startle responses, problems concentrating, and insomnia. Panic attacks occur either unexpectedly or in certain situations (for example, driving), and can require higher dosages of alprazolam.
