Alprazolam is a fast-acting benzodiazepine used to treat anxiety disorders, panic attacks, and sometimes insomnia. It enhances the effect of GABA, a neurotransmitter that calms the nervous system. Commonly sold under the brand name Xanax, alprazolam helps reduce excessive anxiety and promotes relaxation. However, it has a high potential for dependence, tolerance, and withdrawal symptoms, making long-term use risky. Side effects include drowsiness, dizziness, confusion, and impaired coordination. Abrupt discontinuation can lead to severe withdrawal symptoms, including seizures. Due to its potential for abuse, it is classified as a controlled substance and should only be used under medical supervision.
