Antianxiety Drugs

Antianxiety drugs, including the propanediol meprobamate (Miltown or Equanil), and the more recent benzodiazephines—such as diazepam (Valium)—have found wide use in reducing tension and anxiety among individuals with less serious mental disorders, but may lead to addiction if abused. Although they form a chemically diverse group, the physiological effects of each are similar; in small doses they relieve anxiety by reducing muscular tension, and in larger doses they produce sedation, sleep, and anesthesia (see depressant). Antianxiety drugs are the most frequently prescribed pharmaceuticals in the United States.
