Brief Summary:
The principal aim of this exploratory study is to examine whether the addition of aripiprazole to naltrexone will enhance efficacy over naltrexone alone in a 16-week randomized, placebo-controlled clinical trial, in which all subjects will be provided medical management as delivered in the COMBINE Study (Anton et al, 2006). To test whether medication treatment will reduce drinking compared to placebo treatment alone in the context of medical management and whether naltrexone plus aripiprazole will reduce drinking compared to naltrexone treatment alone in the context of medical management.

Active Comparator: 3
Naltrexone + Aripiprazole
Drug: Naltrexone + Aripiprazole

Primary Outcome Measures :
  1. Drinks Per Drinking Day [ Time Frame: 16-week treatment period ]
    Standard drinks per drinking day

  2. Percent Heavy Drinking Days [ Time Frame: 16 weeks ]
    percent of total 112 day trial in which heavy drinking occurred (>=4 for females, >=5 male)

Secondary Outcome Measures :
  1. Pill Counts During Treatment [ Time Frame: 16-week ]
    Compliance with medication as determined by pill counts

  2. Percent Riboflavin Positive Urine Samples as a Measure of Medication Compliance [ Time Frame: 16 weeks treatment trial ]
    Riboflavin was added to each individual capsule of medication and measured as a proxy for compliance with the medication regime
