Brief Summary:
The purpose of this study is to develop and validate a human laboratory model for prediction of medication efficacy in clinical trials for relapse prevention in alcohol dependence.

Condition or disease Intervention/treatment Phase
Alcoholism Drug: Acamprosate Drug: Naltrexone Drug: Placebo Phase 2

Detailed Description:
This is a double-blind, 3-cell, outpatient human laboratory study to determine the degree to which acamprosate and naltrexone will suppress subjective and physiological responsivity to alcohol cues relative to placebo in early abstinence.

Other Name: Campral

Primary Outcome Measures :
  1. Visual Analog Scale of Craving to Drink at 1 Week Following Administration of Acamprosate or Naltrexone or Placebo During the Double-Blind Period [ Time Frame: 1 week ]
    The four Visual Analog Scale questions assess domains of alcohol craving: the intention to drink, loss of control, relief craving, and urge intensity. The scale ranges from 0-20 where a zero indicates no craving and 20 indicates severe craving; thus, a higher score indicates a worse outcome. Total is a summation of the four subscales (i.e. Strength, Intent, Impulse, Relief) and ranges in value from 0-80 with higher scores indicative of a worse outcome.

Secondary Outcome Measures :
  1. Change From Baseline in Standard Drinks Per Week at 1 Week [ Time Frame: 1 week ]
    Standard drinks are equivalent to 14 grams of pure alcohol and number of drinks are assessed with Timeline Follow-Back (TLFB) methods. Change = (Week 1 - Baseline). More negative values indicate less use of alcohol.

  2. Change From Baseline in Mood on the Beck Depression Inventory (BDI-II) at Week 1 [ Time Frame: 1 week ]
    The BDI-II is a self-rating of severity of depressive symptoms. BDI-II Total scores range from 0-63; a lower score indicates less severe depressive systems and thus is a better outcome. Change = (Week 1 score - Baseline score). The Total score is a sum of the 21 items on the BDI-II instrument, with each item rated from 0-3.

  3. Change From Baseline in Sleep Quality on the Pittsburgh Sleep Quality Index (PSQI) Total Score at Week 1 [ Time Frame: 1 week ]
    The PSQI is an instrument to assess subjective sleep quality and disturbance. The Total score ranges from 0 to 21 where a lower score is better sleep quality. Change = (Week 1 score - Baseline score). Seven subscales (range 0-3) are summed to compute the Total score.

  4. Change From Screening in Craving on the Alcohol Craving Questionnaire-Short Form (ACQ-SF) Total Score at Week 1 [ Time Frame: 2 weeks ]
    The ACQ-SF is an assessment of current drinking urges, difficulty resisting urge and anticipation of positive outcome or relief from negative state by drinking. The Total score ranges from 0 to 7 where a lower score is a better outcome. Change = (Week 1 score - Screening score). The scale is comprised of twelve items (range 0-7) that are averaged to compute the Total score.
