Brief summary: This study would like to test whether the combination of ondansetron and naltrexone will be superior to either medication alone or placebo in the treatment of alcohol dependence.

Detailed description: We propose to conduct a 13 week randomized, controlled clinical trial to evaluate the safety and efficacy of ondansetron and naltrexone alone and in combination.Eligible subjects will be randomized to placebo, ondansetron, naltrexone, or ondansetron + naltrexone treatments. All subjects will receive a weekly CBT (Cognitive Behavioral Therapy)sessions.

* Current DSM-IV diagnosis of alcohol dependence
* AUDIT score of equal or more than 8.

* Severe alcohol withdrawal symptoms which in the physicians opinion requires inpatient treatment.
* Serious medical co-morbidity requiring medical intervention or close supervision, or any condition which can interfere with the receipt of ondansetron.
* Severe or life-threatening adverse reactions to medications in the past or during this clinical trial.
* Female patients who are pregnant, lactating, or not adhering to an acceptable form of contraception at any time during the study.
