NCT01214083

Brief Summary

The purpose of this study is to determine whether: (1) the combination of N-acetylcysteine + high-dose naltrexone (150 mg) works better than high-dose naltrexone (150 mg) alone in reducing alcohol drinking; and (2) high-dose naltrexone (150 mg) alone works better than low-dose naltrexone (50 mg) alone in reducing alcohol drinking.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Heavy Drinking Days

    "Percentage of heavy drinking days" was measured by the Time Line Follow Back (TLFB) Method. ('Heavy drinking' was defined as 5 or more standard drinks per day for men and 4 or more standard drinks for women.) The percentage has a total range of 0%-100%. Higher percentages represent a worse outcome (i.e., more heavy drinking).

    week 1 and week 13

Secondary Outcomes (8)

  • Liver Function Tests (AST)

    week 0 and week 13

  • Penn Alcohol Craving Scale (PACS)

    week 1 and week 13

  • Obsessive Compulsive Drinking Scale (OCDS)

    week 1 and week 13

  • Clinical Global Impression (CGI)

    week 1 and week 13

  • Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q)

    week 1 and week 13

  • +3 more secondary outcomes
