A high-potency benzodiazepine, alprazolam amplifies the action of GABA, the brain's principal inhibitory neurotransmitter, by binding the GABA-A receptor and increasing chloride flow into neurons. The enhanced inhibition produces calming, anxiety-reducing, and sedative effects, and it is prescribed for generalized anxiety disorder, panic disorder, and anxiety accompanying depression. A triazolobenzodiazepine small molecule (C17H13ClN4) with a half-life of roughly 6 to 12 hours, it acts relatively quickly, a property that contributes both to its usefulness in acute anxiety and to its potential for dependence. Prolonged use can lead to tolerance and a withdrawal syndrome when stopped abruptly, reflecting the nervous system's adaptation to sustained GABA enhancement. Alprazolam is an approved anxiolytic prescribed under careful supervision because of these risks.

A benzodiazepine medication that enhances the effect of GABA, the brain's main inhibitory neurotransmitter, producing calming, anti-anxiety, and sedative effects. It is prescribed for generalized anxiety disorder, panic disorder, and anxiety associated with depression, though it carries risks of dependence and withdrawal with prolonged use.
