AbstractBackground: There is a paucity of published literature on the optimal treatment of pain in patients on buprenorphine treatment (BT) for opioid use disorder. Using this case report, we hope to demonstrate that tramadol may represent an effective treatment option for pain in patients on BT while encouraging future clinical trials. Case: The patient is a 56-year-old Caucasian male with a history of opiate use disorder on treatment with buprenorphine/naloxone 8/2 mg 2 times a day (BID) who was followed in an outpatient general psychiatry clinic that specializes in patients with co-occurring substance use disorders. Although maintaining sobriety from opioids, the patient continued to struggle with acute on chronic pain secondary to osteoarthritis that had left him walking with a cane. The patient was started on tramadol 50 mg 3 times a day (TID) for acute pain by his primary care physician (PCP) while he awaited surgical intervention. He reported analgesic effect with buprenorphine/naloxone but noted that it did not last the full period between his doses. He reported further improvement in his pain along with greater daily functioning with the additional use of tramadol, without side effects or withdrawal symptoms. Discussion: Current recommendations for pain management in patients on BT include discontinuation of BT therapy and/or addition of an adjunctive opioid analgesic (including additional buprenorphine/naloxone) while continuing agonist medication for treatment of opioid use disorder. However, determining which medication to use can be difficult, as there has been no literature examining this issue. In this case, the combination of buprenorphine and tramadol demonstrated an additive analgesic effect. Randomized control studies need to be performed to further understand the changes in pain measurement in patients on BT with tramadol compared with other adjunctive analgesic medications.
