Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age 18-65
  • Meet DSM-IV-TR criteria for current alcohol dependence with active alcohol use in the past 30 days

  • Must consent to random assignment and be willing to commit to medication treatment and follow-up assessments.
  • Currently under the care of a psychiatrist.
  • Must consent to sign a release of information allowing investigators to communicate with his/her psychiatrist to verify treatment history and facilitate care should treatment-emergent psychiatric symptoms develop during the trial.

    • Lithium level of 0.6 - 1.2 mEq/L
    • Prescribed daily use of first generation antipsychotic agents including chlorpromazine, fluphenazine, or haloperidol or their injectible depot (decanoate) equivalents at a dose adequate to maintain clinical stability as documented by the subject's outpatient psychiatric provider c) Prescribed daily use of second generation antipsychotic agents including olanzapine, risperidone, paliperidone, quetiapine, aripiprazole, or ziprasidone or their injectible depot equivalent at a dose adequate to maintain clinical stability as documented by the subject's outpatient psychiatric provider

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Lamotrigine

Placebo

Arm Description

Add-on lamotrigine plus pre-existing mood stabilizing medication regimen. Active fixed-dose drug titration from 25-200 mg/day over first six weeks, 200 mg/day fixed-dose maintenance for second six weeks

Add-on placebo plus pre-existing mood stabilization regimen for 12 weeks

Outcomes

Primary Outcome Measures

Percent Days Abstinent From Alcohol
Percentage of days in trial without consumption of alcoholic beverages per participant self-report; minimum = 0, maximum = 100; higher numbers indicate better outcome. Percent days abstinent was calculated as: (number of days abstinent per self-report / total number of days in trial)*100.

Secondary Outcome Measures

Percent Heavy Drinking Days
Percentage of days in trial that were heavy drinking days (5 or more drinks/day for men, 4 or more drinks/day for women); minimum = 0, maximum = 100; lower numbers indicate better outcome. Percent heavy drinking days was calculated as: (number of days of heavy drinking per self-report / total number of days in trial)*100.
Biomarkers of Alcohol Use: Carbohydrate-deficient Transferrin (CDT)
Serum levels of biomarkers of alcohol use: carbohydrate-deficient transferrin (CDT) at study endpoint in study completers
Biomarkers of Alcohol Use: Gamma-glutamyltransferase (GGT)
Serum levels of biomarkers of alcohol use: Gamma-glutamyltransferase (GGT) at study endpoint in study completers
Montgomery-Asberg Depression Rating Scale (MADRS) Score
Scores on the Montgomery-Asberg Depression Rating Scale (MADRS) at baseline (all randomized subjects) and at study endpoint (study completers). Scores represent total summed score of ten (10) subscale items; minimum = 0, maximum = 60, higher scores indicate worse outcomes.
Young Mania Rating Scale (YMRS) Scores
Mania/hypomania symptoms at study endpoint as assessed by the Young Mania Rating Scale (YMRS) at baseline (all randomized subjects) and at study endpoint (study completers). Scores represent total summed score of eleven (11) subscale items; minimum = 0, maximum = 60, higher scores indicate worse outcomes.
Neurocognitive Performance (California Verbal Learning Test)
Adjusted scale scores (T scores) on the California Verbal Learning Test (CVLT) of verbal working memory at study endpoint. CVLT Trials 1-5 Free Recall Total measures the sum of all word list items correctly recalled on learning trials 1 through 5. This raw score is converted to a T-score (mean = 50; SD=10) with higher scores indicating better performance.
