All of the following are medications for alcoholism except

A. Naltrexone is used to help manage alcohol dependence by reducing cravings and the pleasurable effects of alcohol. It blocks opioid receptors in the brain, which can help prevent relapse in people trying to stop drinking. B. Valium (diazepam) is a benzodiazepine, typically used to treat anxiety, muscle spasms, and alcohol withdrawal symptoms, but it is not specifically used as a medication for alcoholism treatment itself. While it may be used during withdrawal to manage symptoms, it is not a medication for long-term management of alcohol dependence. C. Antabuse (disulfiram) is used to deter drinking by causing unpleasant reactions (such as nausea and vomiting) if alcohol is consumed. This is a treatment for alcoholism that relies on the patient's compliance to avoid drinking. D. Campral (acamprosate) is used to help people maintain abstinence from alcohol after they've stopped drinking. It works by restoring the balance of neurotransmitters in the brain that may be disrupted by long-term alcohol use.
