Xanax (Alprazolam) – Benzodiazepine Anxiolytic (Rx, Controlled Substance)
Xanax (alprazolam) is a benzodiazepine medication used for the short-term treatment of anxiety disorders and panic disorder.
It works by enhancing the activity of GABA (gamma-aminobutyric acid) in the brain, leading to:
- Reduced anxiety and tension
- Calming of overactive neural activity
- Sedative and relaxing effects
Xanax is known for its rapid onset of action, making it effective for acute anxiety and panic attacks, but it is generally prescribed for short-term use due to dependence risk.
