Naltrexone and coping skills therapy for alcohol dependence. A controlled study

Area of Science:

• Psychiatry
• Clinical Psychology
• Pharmacology

Background:

• Alcohol dependence is a chronic relapsing condition with significant public health burden.
• Pharmacological and psychotherapeutic interventions are key components of treatment.
• Optimizing treatment combinations remains an area of active research.

Purpose of the Study:

• To evaluate the efficacy of naltrexone combined with two distinct manual-guided psychotherapies for alcohol dependence.
• To investigate potential interactions between naltrexone and psychotherapy type on treatment outcomes.

Main Methods:

• A 12-week, double-blind, placebo-controlled trial involving 97 alcohol-dependent patients.
• Randomization to naltrexone or placebo, and to either coping skills/relapse prevention therapy or supportive therapy.
• Assessment of drinking behavior, alcohol-related problems, and abstinence rates.

Main Results:

• Naltrexone demonstrated superiority over placebo across multiple measures, including abstention rates, drinking days, relapse rates, and problem severity.
• A significant interaction was observed between medication and psychotherapy type.
• The highest cumulative abstinence rate was achieved with naltrexone plus supportive therapy.
• For patients who relapsed to drinking, naltrexone plus coping skills therapy resulted in the lowest relapse rates.

Conclusions:

• Naltrexone is an effective medication for treating alcohol dependence.
• The combination of naltrexone with supportive therapy is particularly effective for achieving initial abstinence.
• Naltrexone combined with coping skills therapy may be beneficial in preventing further relapse after an initial drinking episode.
