The purpose of this study is to evaluate the effects of the study medication, memantine (placebo, 20 mg or 40 mg/day) on alcohol drinking behavior in a laboratory setting in which participants are given an initial drink of alcohol followed by the choice to drink up to 12 more drinks over a three-hour period. We hypothesize that memantine will reduce craving and number of drinks consumed prior to and after exposure to the initial drink of alcohol and during the three hour drinking period. We will also evaluate the influence of family history of alcoholism on the efficacy of memantine in reducing alcohol drinking behavior.

Primary Outcome Measures:
  • Number of Drinks Consumed on Day 7 [ Time Frame: Day 7 ] [ Designated as safety issue: No ]
  • Baseline-adjusted Craving (YCS) [ Time Frame: Day 7 ] [ Designated as safety issue: No ]
    Craving for alcohol based on Yale Craving Scale, scores ranging from 0-112 mm on a visual analog scale, with higher measurements indicating higher craving. The baseline-adjusted craving is change score from baseline at Day 7.

Secondary Outcome Measures:
  • Stimulation and Sedation Responses to Alcohol [ Time Frame: Day 7 ] [ Designated as safety issue: No ]
