Abstract

The objective of this study was to determine whether quetiapine plus naltrexone is more effective than naltrexone alone for the treatment of alcohol-dependent patients. This was a double-blind, randomized clinical trial where eligible alcohol-dependent patients were randomized to receive naltrexone (50mg/day) plus quetiapine (25-200mg/day) or naltrexone (50mg/day) plus placebo for 12weeks, and afterwards patients received naltrexone alone during 4 additional weeks. The primary efficacy measures were percent days abstinent, drinks per drinking day, and the relapse rate. Sixty-two patients received a single-blind treatment with placebo plus naltrexone, and they were thereafter randomly assigned to quetiapine plus naltrexone (n=30) or placebo plus naltrexone (n=32). Eleven (36.7%) patients in the quetiapine-treated group and 4 (12.5%) patients in the placebo-treated group withdrew before they completed 12weeks of treatment. There were no statistically significant differences for any primary drinking outcomes between treatment groups. Both regimens were well tolerated. This study failed to demonstrate any additional benefit from the combination of quetiapine and naltrexone compared to naltrexone alone on drinking outcomes.
