Abstract
Patients with opioid addiction who receive prescription opioids for treatment of nonmalignant chronic pain present a therapeutic challenge. Fifty-four participants with chronic pain and opioid addiction were randomized to receive methadone or buprenorphine/naloxone. At the 6-month follow-up examination, 26 (48.1%) participants who remained in the study noted a 12.75% reduction in pain (P = 0.043), and no participants in the methadone group compared to 5 in the buprenorphine group reported illicit opioid use (P = 0.039). Other differences between the two conditions were not found. Long-term, low-dose methadone or buprenorphine/naloxone treatment produced analgesia in participants with chronic pain and opioid addiction.
