ObjectivesEffective strategies are needed to manage individuals with chronic non-cancer pain and coexistent opioid addiction. This study compared opioid discontinuation and opioid replacement protocols.MethodsWe planned to enroll 60 individuals into an open-label trial who had been treated with opioids for chronic non-cancer pain, and who also had opioid addiction. Participants were randomly assigned to one of two 6-month treatment protocols of buprenorphine/naloxone sublingual tablets: 1) tapering doses for opioid weaning or "detoxification" (active comparator group) or 2) steady doses for opioid replacement (experimental group). They were followed monthly for the study outcomes: completion of the 6-month treatment protocol and self-reported pain control, physical functioning, alcohol consumption and illicit drug use.ResultsEnrollment was terminated after enrolling 12 participants because none of the 6 assigned to receive tapering doses could successfully complete the protocol (5 were given steady doses and 1 was admitted to an inpatient chemical dependency treatment program); whereas, of the 6 assigned to receive steady doses, 5 completed the protocol (1 withdrew). This difference between the 2 treatment conditions was significant (P = 0.015). Of the 10 participants who completed the 6 month follow-up, 8 reported improved pain control and physical functioning and 5 used alcohol and/or illicit drugs.ConclusionsWe conclude that over 6 months, these participants with chronic pain and co-existent opioid addiction were more likely to adhere to an opioid replacement protocol than an opioid weaning protocol and that opioid replacement therapy with steady doses of buprenorphine/naloxone is associated with improved pain control and physical functioning.
