Brief Summary:
The purpose of this study is to determine the long-term effectiveness of naltrexone treatment in alcohol-dependent patients who respond to short-term treatment. Those who respond to short-term treatment will be randomized to a 1-year, double-blind, placebo-controlled maintenance phase with a 6-month posttreatment followup.

Condition or disease Intervention/treatment Phase
Alcoholism Drug: Naltrexone Tablet Drug: Matched Placebo Tablet Phase 4

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 159 participants
Allocation: Randomized
Intervention Model: Sequential Assignment
Intervention Model Description: Naltrexone 50 mg was provided for 3 months to all study participants, who were masked regarding the identity of study medication. At 3 months, full and partial responders were randomized to an additional 9 months of double blind treatment with naltrexone or matched placebo. Full responders were defined as complete abstinence for the last six weeks of the acute phase. Partial responders were defined as having no more than 2 heavy drinking days in any given week and/or a 50% reduction in weekly alcohol consumption from baseline over the last six weeks of the acute phase.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: Naltrexone and placebo were identical in appearance and packaging to preserve the double blind.
Primary Purpose: Treatment
Official Title: Nalmefene Maintenance Treatment of Alcoholism
