title: Opioid detoxification using high doses of buprenorphine in 24 hours: a randomized, double blind, controlled clinical trial.
abstract: In recent years, interest in shortening of opioid detoxification has increased with the rising demands to find more cost-effective approaches for treatment of opioid dependence. This study was designed to evaluate the efficacy of administration of high doses of buprenorphine during 24 h in the management of acute opioid withdrawal. A total of 40 treatment-seeking opioid dependents were admitted and randomly assigned to two groups in a double blind, parallel trial. Buprenorphine was administered intramuscularly. Twenty patients received 12 mg buprenorphine in 24 h and the remaining 20 patients treated with conventional doses of buprenorphine tapered down over 5 days. Variables that were assessed included retention in treatment, rates of successful detoxification, the Subjective Opiate Withdrawal Scale (OOWS) scores, the Objective Opiate Withdrawal Scale (SOWS) scores, intensity of craving, drug side effects, and levels of hepatic enzymes (ALT and AST). There was no significant difference between the two groups on most variables. The main difference was in the time that maximal withdrawal symptoms occurred, which in the experimental protocol group appeared early while in the conventional protocol group appeared later during the detoxification period. Moreover, the experimental protocol was not only tolerated well but also accompanied with significantly less elevation in the ALT levels compared to the conventional treatment. However, patients in this group used more indomethacin and trazodone for symptom palliation. This study suggests that administration of high doses of buprenorphine in 24 h may be a reasonable approach for shortening of opioid detoxification. However, a larger study to confirm our results is warranted.
