Which group of medications is categorized as anti-anxiety medications?

The correct classification of anti-anxiety medications includes benzodiazepines, tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), and buspirone. Benzodiazepines are commonly prescribed for their sedative properties and rapid relief of anxiety symptoms. They work by enhancing the effects of the neurotransmitter gamma-aminobutyric acid (GABA), which has a calming effect on the brain.

TCAs, although primarily used as antidepressants, are also effective in treating some anxiety disorders. They influence various neurotransmitters, including serotonin and norepinephrine, which can help stabilize mood and reduce anxiety. SSRIs are similarly positioned; they primarily target serotonin levels, improving mood and anxiety as a result. Buspirone, on the other hand, is specifically an anxiolytic medication that works differently from benzodiazepines, as it is not sedating and has a lower risk of dependency.

In contrast, the other groupings do not accurately represent anti-anxiety medications. SSRIs and buspirone are indeed valid examples of anxiety treatment options, but opioids mentioned in another option are primarily pain-relievers and do not serve an anti-anxiety purpose.
