An anxiolytic (also antipanic or antianxiety agent) is a medication or other intervention that inhibits anxiety. This effect is in contrast to anxiogenic agents, which increase anxiety. Together these categories of psychoactive compounds or interventions may be referred to as anxiotropic compounds/agents. Some recreational drugs such as ethanol (alcohol) induce anxiolysis initially, however studies show that many of these drugs are anxiogenic. Anxiolytic medications have been used for the treatment of anxiety and its related psychological and physical symptoms. Anxiolytics have been shown to be useful in the treatment of anxiety disorders. Light therapy and other interventions have also been found to have an anxiolytic effect.
