Buprenorphine/Naloxone Versus Clonidine for Inpatient Opiate Detoxification

The purpose of this study is to assess buprenorphine/naloxone versus clonidine for inpatient
opiate detoxification.

Patients randomized to the BUP/NX arm will receive daily doses for 13 days with sublingual
administration of 2 mg buprenorphine/0.5 mg naloxone tablet(s) and/or an 8 mg
buprenorphine/2.0 mg naloxone tablet(s). The starting dose on day 1 is 4 mg/1 mg BUP/NX with
an additional 4 mg/1 mg, if needed, escalating in a step-wise manner to 16 mg/4 mg BUP/NX on
day 3 and tapering to 2 mg/ 0.5 mg BUP/NX by days 12 to 13. Patients randomized to the
clonidine arm will receive oral clonidine (0.05 to 0.1 mg depending upon weight) every 4 to
6 hours for 24 hours not to exceed 0.6 mg total on day 1. On day 2, a clonidine transdermal
patch will be applied (0.1 mg/day/7-day patch with number of patches adjusted by weight).
Oral clonidine will continue to be given on the second day of detoxification and increased
to 0.2 mg every 6 hours or 0.1 mg every 3 hours not to exceed 0.8 mg over 24 hours. Patches
will be worn all 13 days of detoxification. The dose of clonidine will be adjusted according
to the proposed detoxification schedule, patient's weight, tolerance, and systolic blood
pressure. Patients will receive counseling according to procedures in existence at each CTP
throughout the study. Self-help detoxification handbooks will be distributed to all study
participants.
