Tranquilizer drug. Capsules of a tranquilizer drug, in this case a benzodiazepine anxiolytic, beside a glass of water. There are several benzo- diazepine anxiolytics, including diazepam (valium). This class of drugs is widely used to relieve severe anxiety and muscle spasms. Side-effects include drowsiness, light-headedness, confusion, amnesia and loss of muscle coordination (ataxia). Long-term use may lead to addiction and tolerance. Tranquilizer drugs promote mental and physical relaxation by reducing the nerve activity of the brain.
