Which medication is commonly used for managing anxiety?

Alprazolam is a medication that belongs to the benzodiazepine class, which is commonly prescribed for managing anxiety disorders and panic attacks. It works by enhancing the effect of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA), which has a calming effect on the central nervous system. This makes it effective in reducing excessive nervousness and anxiety symptoms.

In contrast, the other options listed serve different therapeutic purposes. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) primarily used for pain relief and reducing inflammation. Amoxicillin is an antibiotic used to treat bacterial infections, and it does not have any role in managing anxiety. Metformin is an oral medication used to manage blood sugar levels in individuals with type 2 diabetes, which is completely unrelated to the treatment of anxiety.
