About

The purpose of this research study is to study the effects (both good and bad) of combining quetiapine and topiramate for treating symptoms of bipolar mania (an illness with periods of elation, excessive excitement, irritability, high energy, racing thoughts, poor sleep, poor judgment, reckless behavior) and to study the effects (both good and bad) of combining quetiapine and topiramate for reducing use of alcohol.

Full description

Specific Aim 1: To collect preliminary data regarding the efficacy and tolerability of topiramate for the treatment of alcohol use disorders (alcohol abuse and dependence) in adolescents with bipolar disorder.

Hypothesis 1: We hypothesize that topiramate in combination with quetiapine will lead to greater reduction in alcohol consumption (number of drinks per day, number of drinks per drinking day, and number of heavy drinking days) and greater abstinence (percentage of days abstinent) compared with quetiapine alone.

Specific Aim 2: To obtain preliminary data regarding the efficacy of topiramate for reducing manic symptoms in adolescents with co-occurring alcohol use and bipolar disorders.

Hypothesis 2: We hypothesize that the topiramate in combination with quetiapine will produce greater reduction in Young Mania Rating Scale (YMRS) scores than quetiapine alone.

Provision of written informed consent/assent; 8) If female and of child bearing potential, agrees to use one of the following method of birth control: complete abstinence, barrier (diaphragm or condom), or oral contraceptive containing > 35 micrograms of ethinyl estradiol (because concomitant use of topiramate and lower estrogen oral contraceptives may lead to contraceptive failure).

Exclusion criteria

1. Manic symptoms resulting from acute medical illness or acute intoxication or withdrawal from drugs or alcohol as determined by medical evaluation and rapid symptom resolution;

8. Treatment with concurrent mood stabilizers, antipsychotics or antidepressants;
9. Treatment with antipsychotics or other mood stabilizers within 72 hours and antidepressants within 5 days prior to randomization;
10. Treatment with fluoxetine within one month;
11. A history of non-response or hypersensitivity to quetiapine or topiramate;
12. Serious suicidal ideation (> 3 on the CDRS-R89 suicide item, or any serious suicide attempt within the prior 60 days as judged by the investigator; 3=has thoughts about suicide or hurting themselves usually when angry);
