An ataraxic drug or medication is a substance that reduces or suppresses anxiety and promotes a state of calm and relaxation in the body. Common synonyms for ataraxic drugs include anxiolytics, sedatives, tranquillizers, and anti-anxiety medications. They work by increasing the levels of certain neurotransmitters in the brain that inhibit the production of stress hormones and reduce the activity of the nervous system. Some commonly used ataraxic drugs include benzodiazepines such as Valium and Xanax, as well as non-benzodiazepines such as Buspirone and Hydroxyzine. Although these drugs are beneficial for treating anxiety disorders and promoting relaxation, they can also have side effects such as drowsiness, dizziness, and addiction.
