## **Core Concept**
Anxiolytic drugs are used to treat anxiety disorders. They primarily work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA_A receptor, resulting in sedative, hypnotic (sleep-inducing), anxiolytic (anti-anxiety), anticonvulsant, and muscle relaxant properties. Common classes include benzodiazepines and azapirones.

## **Why the Correct Answer is Right**
works as an anxiolytic by acting on the GABA_A receptor. On the other hand, is known for its different mechanism of action. It is actually a drug used for treating depression and works by inhibiting the reuptake of serotonin and norepinephrine, thus acting as an antidepressant.

## **Why Each Wrong Option is Incorrect**
* **Option A:** is a benzodiazepine, which is a class of drugs well-known for their anxiolytic effects.
* **Option B:** is also a benzodiazepine, used for its anxiolytic, muscle relaxant, and sedative properties.
* **Option C:** is an azapirone, which acts as a partial agonist at the 5-HT1A receptor and is used for its anxiolytic effects.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that while benzodiazepines and certain other classes are used for their anxiolytic effects, drugs like (an antidepressant) are not primarily used for anxiety relief but can be used in certain cases of anxiety disorders.
