Which medication is moderately effective for relapse prevention in alcohol use disorder?

• A. Naltrexone
• B. Acamprosate
• C. Disulfiram
• D. Gabapentin

Answer: (B)

Relapse prevention in alcohol use disorder relies on medications that help sustain abstinence after detox. Acamprosate works by stabilizing glutamatergic neurotransmission as the brain recovers from years of alcohol exposure. This helps reduce cravings and the risk of returning to drinking, making it modestly effective for keeping people abstinent and delaying relapse, especially when started after detox and paired with ongoing psychosocial support. It’s also relatively safe for the liver, which makes it a good option for patients with liver concerns. Naltrexone, while useful, mainly reduces the rewarding effects of alcohol and lowers relapse risk in people with strong cravings or a pattern of heavy drinking, but its impact on sustaining abstinence is more variable. Disulfiram creates an aversive reaction to alcohol, but adherence is a major limitation, so its relapse-prevention effectiveness depends heavily on whether the patient stays compliant. Gabapentin has some supportive data for reducing drinking and managing withdrawal symptoms, but it isn’t as robust or widely used specifically for relapse prevention as acamprosate. So, acamprosate is the best match for moderately effective relapse prevention when the goal is to maintain abstinence after detox.
