Tramadol versus buprenorphine for the treatment of opiate withdrawal: a retrospective cohort control study.
Various drugs have been used for the treatment of opioid withdrawal, e.g., methadone, buprenorphine, and clonidine. Tramadol is a centrally acting synthetic analgesic agent with opiate activity due to low affinity binding of the parent compound and higher affinity binding of the O-demethylated metabolite M1 to mu opioid receptors. As a consequence, there may be a role for the use of tramadol in the treatment of opiate withdrawal. We attempt to assess the efficacy of tramadol in treating moderate heroin withdrawal through a retrospective cohort control study, conducted in a detoxification unit in a community teaching hospital. Out of 100 heroin abusers admitted for detoxification during the review period, 64 patients who were treated either with buprenorphine or tramadol, were included in this study, with 20 participants in the buprenorphine group and 44 in the tramadol group. Both groups were matched for age, sex, and self-reported average quantity of heroin used per day. In the tramadol group, the average CINA maximum was 9.0, and in the buprenorphine group it was 11.2 (P = 0.07). The use of oral clonidine per patient in the tramadol group was 1.6 tablets, and in the buprenorphine group 0.1 tablets (P = 0.002). The length of stay was 3.7 days in the tramadol group and 4.1 days in the buprenorphine group (P = 0.5). Four participants in the tramadol group received three or more doses of buprenorphine because their symptoms were not controlled, and were considered as treatment failures. These preliminary data suggest that tramadol may be comparable to buprenorphine in the management of mild to moderately severe heroin withdrawal. These findings, if reproduced in larger studies with stronger research designs, have potentially great implications for the management of opioid withdrawal in both the inpatient and outpatient setting.
