Which of the following drugs is commonly prescribed for anxiety disorders?

Alprazolam is commonly prescribed for anxiety disorders because it is a benzodiazepine that works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA). This action leads to a calming effect on the brain and nervous system, making it effective for treating conditions such as generalized anxiety disorder and panic disorder. It helps to alleviate symptoms of anxiety quickly, which is often desired in clinical settings.

While fluoxetine, a selective serotonin reuptake inhibitor (SSRI), is also used to treat anxiety disorders, it is primarily known for its role in treating depression and may take several weeks to achieve its full effect on anxiety. Gabapentin is typically prescribed for nerve pain and seizures and is not a first-line treatment for anxiety. Hydrochlorothiazide is a diuretic used for managing high blood pressure and does not have a role in treating anxiety disorders.
