Effectiveness of Sertraline in Treating Pathological Gamblers With a Diagnosis of Alcohol Dependence - 1

• Decreased gambling behavior; measured throughout study
• Decreased alcohol consumption; measured throughout study and at Week 10

Pathological gamblers often are also dependent on alcohol and clinically depressed. Sertraline (Zoloft) is currently used to treat depression, panic disorder, and obsessive-compulsive disorder. The purpose of this trial is to determine the effectiveness of sertraline used in combination with relapse prevention therapy in decreasing gambling behavior and alcohol consumption in individuals with a diagnosis of pathological gambling and alcohol abuse or dependence.

Alcohol abuse and depression commonly occur in conjunction with pathological gambling. Sertraline (Zoloft) is a selective serotonin reuptake inhibitor (SSRI) currently used to treat depression, panic disorder, and obsessive-compulsive disorder. The purpose of this trial is to determine the effectiveness of sertraline combined with relapse prevention therapy in decreasing gambling behavior and alcohol abuse.

Participants in this 10-week trial will be randomly assigned to receive either relapse prevention (RP) therapy and sertraline or RP therapy and a placebo. Participants will begin taking 25 mg of either sertraline or placebo in a single morning dose for one week. If, after one week, participants do not show improvement, the dose will increase to 50 mg per day during Week 2, and will increase by 50 mg per day every week thereafter to a maximal dose of 200 mg per day.

Weekly hour-long study visits will include a medication evaluation, RP therapy, and questionnaires. In addition, evaluations at baseline, Week 5, and Week 10 will include pathological gambling and depression ratings, urine drug screens, and biochemical measures of alcohol consumption and liver function. All other weekly study visits will include evaluation of side effects, an interview on alcohol use, measures related to obsessive-compulsive drinking, and assessments of vital signs and concomitant medications.
