Naltrexone appears to be an effective and safe strategy in alcoholism treatment. Even though the sizes of treatment effects might appear moderate in their magnitudes, these should be valued against the background of the relapsing nature of alcoholism and the limited therapeutic options currently available for its treatment.
The use of naltrexone to treat ambulatory patients with alcohol dependence.
The purpose of this study is to evaluate the efficacy of Naltrexone in decreasing craving symptoms among Puerto Rican male veterans with alcohol dependence.
                This is a double blind placebo control study with a convenience sample of eleven patients divided in two groups (placebo and Naltrexone). Scales consisting of Zung Depression, Zung Anxiety, MMSE, OCD Screener, Craving, and Somatization were administered at baseline, and weekly for four weeks as follow up.
                There were no statistically significant differences between the two groups on any of the outcome variables at baseline or follow up measurements. A statistical trend was noted toward a decrease in somatization. A decrease in craving symptoms was observed in the experimental group.
                Even though our results did not show evidence of the efficacy of Naltrexone in decreasing craving symptoms, a small number of patients did benefit from the medication. The results could have been affected by the small sample size.
