Other Names:
  • Seroquel
  • Xeroquel
  • Ketipinor

Detailed Description:

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.
