Hazardous drinking is particularly harmful in HIV-infected persons. It impairs the immune system, accelerates HIV disease progression, slows initiation of antiretroviral therapy (ART) and decreases adherence. Thus, the development of effective alcohol treatments for this clinical population is particularly important. The investigators are proposing to investigate the effectiveness of ondansetron pharmacotherapy for the treatment of hazardous alcohol use and alcohol abuse/dependence among HIV-infected patients. Ondansetron, a 5-HT3 antagonist, will be studied for several reasons: 1) evidence of effectiveness in persons who want to cut-down or reduce their drinking and who are not abstinent at medication initiation; 2) moderate-to-strong effects among early onset problem drinkers, a characteristic that is over represented in our clinic patients; 3) a very mild side-effect profile, making it an ideal pharmacotherapy candidate in patients who are often receiving multiple other medications with significant side-effects; and 4) its primary indication is for treatment of nausea, a common side-effect of antiretroviral (ARV) medications.
The proposed study is a placebo-controlled, randomized clinical trial of ondansetron for the treatment of hazardous drinking and alcohol use disorders among HIV-infected patients recruited from the Baltimore/Washington area. Participants will be genotyped for a functional polymorphism of the serotonin transporter gene. They will be randomized to one of three treatment groups: placebo, low dose ondansetron (0.2 mg bid) and moderate dose ondansetron (0.8 mg bid). All subjects will undergo 16 weeks of pharmacotherapy in combination with medication management, and will be followed for 3 and 6 months after medication has ended.

Placebo Comparator: Placebo Ondansetron - sugar pill
Placebo is an oral preparation made to appear and taste like the active drug preparation.
Drug: placebo ondansetron
Matching placebo will be prepared using a colorless strawberry syrup, simple syrup and flat Schweppes tonic water.

- Number of Alcoholic Containing Drinks Per Drinking Day [ Time Frame: 16 weeks ]The Time-line Follow-back (TLFB; Sobell, Sobell, Leo & Cancilla, 1988) is conducted as an interview administered by trained and certified research staff. The interview obtains participant self-reports of daily drinking, including number and type of alcoholic beverages. These data are used to quantify an individual's drinking pattern including the number of drinks per drinking day and drinking frequency. The TLFB was completed biweekly and quantified over the 16-week medication period
- Number of Days/Week Abstinent From Alcohol [ Time Frame: 16 weeks ]The Time-line Follow-back (Sobell, Sobell, Leo & Cancilla, 1988) is used to obtain this secondary dependent measure. Alcohol use will be assessed biweekly and quantified over the 16-week medication period. Number of days/week abstinent from alcohol is calculated as the number of abstinent days divided by the number of study medication days (adjusted for days in confinement (e.g., hospitalization; jail)) and multiplied by 7.
- Medication Safety [ Time Frame: 16 weeks ]Medication side-effects and adverse events were measured using the Systematic Assessment for Treatment of Emergent Events (SAFTEE). The SAFTEE contains 25 detailed questions that systematically address 29 body systems. A trained interviewer elicits information about onset, duration, pattern, and judgment of attribution. For the present trial outcome, we report number of events.
- Number of Subjects Who Discontinue Due to Side Effects [ Time Frame: 16 weeks ]The investigators will count the number of subjects who discontinue medication during the 16-week intervention period due to complaints of side effects.
- Alcohol-related Problems [ Time Frame: 16 weeks ]Alcohol-related problems were measured using the Short Inventory of Problems - revised (SIP-R), a self-report inventory of adverse consequences associated with alcohol and drug use. The SIP instructs participants to indicate how often each of 15 consequences has occurred during the past three months ("never," "once or a few times," "once or twice a week," "daily or almost daily"; scored 0-3). Item responses are summed to produce a total score and five subscale scores. Total scores range from 0 - 45.
- HIV Medication Adherence [ Time Frame: 16 weeks ]The investigators will obtain patient self reports of the number of HIV medication doses taken as a function of the total number of doses prescribed. The adherence measure is expressed as the % of prescribed doses.
