Prescription Opioid Abuse Among Pain Patients: Predictors of Relapse

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.
