Placebo Comparator: Placebo
This group will be given placebo matching quetiapine for the course of the 12 weeks in the study.
Inactive ingredient matching the active medication in appearance.
Other Name: Sugar-pill
Active Comparator: Quetiapine
This group will be given 50mg Quetiapine per day baseline-week 1, 100mg Quetiapine per day week 1-week 2, 200mg Quetiapine per day week 2-week 3, 400mg Quetiapine per day week 3-week 4, and 600mg Quetiapine per day week 4 to week 12.
Quetiapine is an atypical antipsychotic approved for the treatment of schizophrenia, bipolar disorder, and in the XR version along with an SSRI to treat major depressive disorder.
The primary aim in the study is to determine if quetiapine treatment is associated with greater reduction in alcohol use than placebo in outpatients with bipolar disorder and alcohol dependence. We will also examine if quetiapine treatment is associated with greater reduction in alcohol craving than placebo in outpatients with bipolar disorder and alcohol dependence and if quetiapine treatment is associated with greater improvement in depressive symptoms than placebo in outpatients with bipolar disorder and alcohol dependence.
