Which medication is commonly used to relieve anxiety?

Benzodiazepines are commonly prescribed for the short-term relief of anxiety symptoms due to their fast-acting properties. They work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which has a calming effect on the nervous system. This makes benzodiazepines effective for acute anxiety management, such as in situations of panic attacks or severe anxiety episodes.

While SSRIs (Selective Serotonin Reuptake Inhibitors) are also used for anxiety, particularly in a more chronic context, they take longer to exert their effects, requiring weeks for full therapeutic benefits. Tricyclics can be effective for anxiety, but they are less commonly used specifically for anxiety today due to their side effect profile. Buspirone may be used for anxiety management, especially as a non-benzodiazepine option, but it is generally more appropriate for generalized anxiety disorder and also takes some time to become effective.

In summary, when considering the typical fast-acting treatment for anxiety, benzodiazepines are clearly recognized as the primary class of medications used for immediate relief, making them the correct answer in this scenario.
