Brief Summary:
The purpose of this study is to evaluate the combined effects of the study medications naltrexone and memantine on alcohol drinking behaviors.

Condition or disease Intervention/treatment Phase
Alcohol Drinking Drug: Naltrexone and memantine first Drug: Naltrexone and Placebo first Phase 2

Detailed Description:
Participants will be randomized to receive a combination of naltrexone/memantine over a one week period and then participate in a laboratory session. During this session, participants are given an initial drink of alcohol followed by the choice to drink up to 12 more drinks over a three-hour period. These medications are hypothesized to 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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Drinks Consumed at Lab Session (Day 7) [ Time Frame: Day 7 ]
    Number of drinks consumed during the lab session (Day 7) after taking study medication, ranging from 0-12.

  2. Craving AUC: Adlib Drinking Phase [ Time Frame: 50-230 minutes after the priming drink during lab session ]
    Craving for alcohol based on Alcohol Urge Questionnaire (AUQ, Bohn et al., 1995), which is an 8 item measurement of self-reported alcohol urges that has been shown to be strongly related to alcohol dependence severity. Each item is scored from 1 (strongly disagree) to 7 (strongly agree), with a higher score indicating higher craving. Assessed multiple times, starting at 50 minutes after priming drink until 230 minutes after priming drink. Higher craving scores (ranging from 0-56) are indicated by larger log-transformed AUC.

  3. Stimulation Response to Alcohol at Lab Session [ Time Frame: 50-230 minutes after the priming drink during lab session ]
    Brief Biphasic Alcohol Effects Scale-Stimulation subscale (BAES; Martin et al., 1993), measuring stimulation effects of alcohol. Seven items ranging from 0 (not at all) to extremely (10) with higher measurements indicating higher stimulation. Assessed multiple times, starting at 50 minutes after priming drink until 230 minutes after priming drink. Higher stimulation scores (ranging from 0-70) are indicated by larger log-transformed AUC.

  4. Sedation Response to Alcohol at Lab Session [ Time Frame: 50-230 minutes after the priming drink during lab session ]

    Brief Biphasic Alcohol Effects Scale-Sedation subscale (BAES; Martin et al., 1993), measuring sedation effects of alcohol. The seven items included on the sedation subscale range from 1 (not at all) to extremely (10) with higher measurements indicating higher sedation. Assessed multiple times, starting at 50 minutes after priming drink until 230 minutes after priming drink. Area Under the Curve was used to calculate the final score reported for the BAES.

    As a single summary measure, AUC, was calculated for BAES outcomes based on scores recorded at numerous time points throughout the adlib drinking session The calculation was based on the trapezoidal methods using times 50, 90, 110, 150, 170, 210, and 230 . Based on the distribution, each AUC was log-transformed. Higher AUC levels correspond to greater levels of sedation.


  5. Craving AUC: Priming Dose Phase [ Time Frame: 0-50 minutes after the priming drink ]
    Craving for alcohol based on Alcohol Urge Questionnaire (AUQ, Bohn et al., 1995), which is an 8 item measurement of self-reported alcohol urges that has been shown to be strongly related to alcohol dependence severity. Each item is scored from 1 (strongly disagree) to 7 (strongly agree), with a higher score indicating higher craving. Craving for alcohol based on Alcohol Urge Questionnaire is calculated using Area Under the Curve (AUC). A single summary measure, AUC was calculated for AUQ outcomes based on scores recorded at numerous time points throughout the priming drink session. The calculation was based on the trapezoidal methods using times -20, 10, 20, 30, 40, 50 minutes before/after priming drink. Based on the distribution, each AUC was log-transformed. Higher AUC levels correspond to greater alcohol urge.

  6. Sedation Response to Alcohol: Priming Dose Phase [ Time Frame: 0-50 minutes after priming drink ]
    Brief Biphasic Alcohol Effects Scale-Sedation subscale, measuring sedation effects of alcohol with higher measurements indicating higher sedation. Brief Biphasic Alcohol Effects Scale-Stimulation subscale (BAES; Martin et al., 1993), measuring stimulation effects of alcohol. Seven items ranging from 0 (not at all) to extremely (10) with higher measurements indicating higher stimulation. The subscale total range is 0-70, these scores are logged transformed.

  7. Stimulation Response to Alcohol: Priming Dose Phase [ Time Frame: 0-50 minutes after priming drink ]
    Brief Biphasic Alcohol Effects Scale-Stimulation subscale, measuring stimulation effects of alcohol with higher measurements indicating higher stimulation. Brief Biphasic Alcohol Effects Scale-Stimulation subscale (BAES; Martin et al., 1993), measuring stimulation effects of alcohol. Seven items ranging from 0 (not at all) to extremely (10) with higher measurements indicating higher stimulation. The subscale total range is 0-70, these scores are logged transformed.
