Alprazolam and Zolpidem serve different roles. Alprazolam, a benzodiazepine, treats anxiety and panic by enhancing GABA activity, producing calming effects but with a risk. Zolpidem is a sedative-hypnotic used for short-term insomnia, helping initiate sleep with less daytime anxiety relief. Both can cause drowsiness and dependence, but differ in duration, primary use, and side-effect profiles, requiring careful medical supervision.
