Recent developments in the pharmacotherapy of alcohol dependence

The effectiveness of a treatment for alcohol dependence can be appropriately determined only after controlling for the usual clinical course of alcoholism, subgroups of alcohol-dependent individuals, and placebo effects. The results of appropriate treatment trials must also be interpreted in light of the side effects and costs, and there must be assurances that the overall improvement in functioning observed with the drug is significant enough to outweigh the liabilities. In addition, medications are almost always used in combination with education, counseling, and behavioral therapies, and the impact of these additional treatments must be considered. Viewed from this perspective, 3 medications are quite promising regarding their potential future impact in the alcohol field, including naltrexone, the medication with the most available data in the United States. There are additional data regarding buspirone and acamprosate. Intriguing results have also been generated regarding medications that affect serotonin and dopamine brain activity and with alcohol-sensitizing drugs such as disulfiram. However, none of these medications has been proven to be clinically effective in the routine treatment of the average alcoholic. It is hoped that future research will help identify subgroups of alcohol-dependent men and women who are most likely to respond to specific pharmacological treatments.
