Summary

In this study, we will assess opioid self-administration in a laboratory setting in persons with pain who have a history of opioid abuse. Participants diagnosed with mild to moderate pain will be admitted to hospital for 7 weeks and transitioned from their baseline prescription opioid to a standing daily dose of Suboxone (buprenorphine/naloxone combination). During this maintenance period, participants will have the opportunity in a laboratory setting to self-administer oxycodone; subjective responses as well as analgesic, physiological and performance effects will be measured. In the second phase of this study, the same patients who participated in the inpatient phase will be followed on an outpatient basis while maintained on Suboxone for 12 weeks. . The hypotheses of this study are that (1) higher progressive ratio break-point values for oxycodone, higher subjective ratings of euphoria, and less pain relief will predict early relapse to opioid abuse; (2) the abuse liability measures will be more strongly correlated with relapse than the pain measures; (3) subjective ratings of euphoria will increase and of pain will decrease in an oxycodone dose-dependent manner (i.e. euphoria will increase and pain will decrease as dose increases); and (4) experimentally induced pain will decrease in an oxycodone dose-dependent manner.

Conditions

  • Opioid Dependence

Interventions

DRUG

buprenorphine/naloxone combination

Buprenorphine/naloxone (Bup/Nx; Suboxone sublingual tablets, Reckitt Benckiser) will be administered sublingually at daily doses of 2/0.5, 8/2 mg, and 16/4 mg, which are within the recommended dose range for treating both pain and opioid abuse. The total daily dose will be divided and administered on a QID dosing regimen (0.5/0.125, 2/0.5, and 4/1 mg QID at 0830, 1230, 1730, 2130). Each participant will be tested with all three doses in random order for two weeks at each dose (one week of stabilization followed by one week of testing). Following completion of the 7-week inpatient phase, participants will be maintained on 16/4 mg Bup/Nx.
