Acamprosate, sold under the brand name Campral, is a medication which reduces cravings in alcoholism. It is thought to stabilize chemical signaling in the brain that would otherwise be disrupted by alcohol withdrawal. When used alone, acamprosate is not an effective therapy for alcohol use disorder in most individuals, as it only addresses withdrawal symptoms and not addiction. It facilitates a reduction in alcohol consumption as well as full abstinence when used in combination with psychosocial support or other drugs that address the addictive behavior.
