Unraveling the Puzzle: Why Buprenorphine May Not Be the Panacea for High-Dose Opioid Patients Facing Chronic Pain
A recent randomized clinical trial published in JAMA Internal Medicine has yielded surprising results, challenging long-held assumptions about buprenorphine‘s efficacy in managing chronic pain for patients on high-dose, long-term opioid therapy (LTOT).
The study, conducted between October 2017 and March 2021 at Veterans Affairs primary care clinics, involved 207 patients (meen age 60.9 years; 89.4% men) experiencing moderate-to-severe chronic pain despite receiving at least 70 mg of opioids daily for three months. Researchers aimed to determine if offering buprenorphine as an alternative treatment option would lead to improved pain scores and reduced opioid dosage.
Participants were randomly assigned to one of two groups: a buprenorphine option group, offered the chance to switch to buprenorphine, and a control group, wich received standard care without the buprenorphine option. The study’s primary outcome measure was the Brief Pain Inventory (BPI) score at 12 months, with secondary outcome measures focusing on opioid dose reduction, measured in morphine milligram equivalents (MME).
Of the 207 participants, 175 completed the 12-month follow-up, with 187 included in the primary BPI analysis. The initial BPI scores were identical for both groups, averaging 6.8. After 12 months, the buprenorphine group reported a mean BPI of 6.1, while the control group reported a mean BPI of 6.3—a statistically insignificant difference.
“Persons receiving long-term opioid therapy (LTOT) for pain,especially at high doses,typically experience physical dependence. In physical dependence, reducing or discontinuing opioids may cause unpleasant withdrawal symptoms, including increased pain and dysphoria, that can last for weeks, months, or even years,”
wrote authors of the study.
Similarly, the reduction in daily opioid dosage was minimal. The buprenorphine group showed a mean daily opioid dosage of 157 MME, compared to 165 MME in the control group—again, a statistically insignificant difference.
“We hypothesized the intervention could provide benefits directly, through pharmacologic effects, for those who switched or indirectly by possibly increasing patients’ willingness to try changes to their opioid regimen,”
the authors continued.
“Our findings did not support this hypothesis.”
While the study’s findings challenge the assumption of buprenorphine’s broad effectiveness in this specific patient population, it’s crucial to note that buprenorphine remains a vital treatment for opioid use disorder (OUD). The National Institute on Drug Abuse reported an estimated 2.7 million patients over 12 years old reported OUD in 2020. The American Medical Association estimates that OUD develops in 3% to 19% of patients taking prescription pain medications. the Centers for Disease control and Prevention (CDC) reported 4.7 buprenorphine prescriptions dispensed per 100 people in 2023,highlighting its widespread use.
“In patients with opioid use disorder (OUD), high-quality evidence supports buprenorphine’s effectiveness for treating withdrawal and achieving sustained abstinence from illicit opioids,”
the study authors noted.
“Observational evidence suggests buprenorphine may be similarly effective for successful discontinuation of full agonist opioids in patients receiving LTOT for pain without OUD.”
buprenorphine, a partial opioid agonist, offers a safer profile than full opioid agonists. However,this study underscores the need for further research to fully understand its role in managing pain and OUD in patients already on high-dose opioid therapy. As the authors concluded: “In this randomized clinical trial,offering the option to switch to buprenorphine from high-dose full agonist opioids did not improve pain severity or opioid dosage reduction compared with not offering the option; both groups improved on main measures,”

Opening Statement:
Is buprenorphine the silver bullet for chronic pain management in patients on high-dose opioid therapy? A recent study suggests the answer isn’t as straightforward as we might think.
Interview with Dr. Marcus Reynolds, Pain Management Specialist and addiction Medicine Expert
Editor: Dr. Reynolds, recent research has called into question the efficacy of buprenorphine as a solution for managing chronic pain in patients on high-dose opioid therapy.Can you shed some light on why this might be the case?
Dr. Reynolds: Certainly. The complexities surrounding high-dose opioid therapy involve more than just substituting one medication for another. Patients on long-term opioid therapy often experience physical dependence, which means their bodies have adapted to the presence of these drugs. When these patients attempt to switch to buprenorphine, a partial opioid agonist, they may still face withdrawal symptoms that can be quite severe, including increased pain and dysphoria. This complicates the transition and may negate the potential benefits of buprenorphine in reducing pain severity or opioid dosage.
Editor: With the study showing minimal differences in pain scores and opioid dosage reduction between those offered buprenorphine and those who weren’t, what do you think are the broader implications for pain management and opioid dependency treatment?
Dr. Reynolds: The findings suggest that while buprenorphine is effective for treating opioid use disorder (OUD), its role in managing chronic pain alongside high-dose opioid therapy is less clear-cut. this underscores the need for a tailored approach when treating individuals with chronic pain. One size does not fit all in pain management, particularly in high-dose opioid users.Clinicians must weigh the benefits and potential withdrawal-related challenges of transitioning to buprenorphine, and they may need to incorporate additional therapies, such as physical therapy, cognitive-behavioral therapy, or other non-opioid medications to effectively manage pain.
Editor: Given that buprenorphine remains a vital treatment for OUD, could you discuss its effectiveness for patients who do not have an opioid use disorder but are on high-dose opioids for other medical reasons?
Dr. Reynolds: Observational studies have suggested that buprenorphine might help some patients discontinue full agonist opioids, even in the absence of OUD. However, the effectiveness of buprenorphine in such cases appears to be highly individual.Factors like the patient’s pain threshold, psychological state, and overall medical profile play meaningful roles. Buprenorphine offers a safer profile than full opioid agonists, which is crucial, but as the study indicates, its benefits in terms of lowering opioid dosage and reducing pain for those without OUD are not global.
Key Insights and Recommendations
- Personalized Treatment Plans: Always consider individual patient factors when transitioning from high-dose full agonist opioids to buprenorphine or any other medication.
- Combating physical Dependence: Understand and prepare for potential withdrawal symptoms by coordinating care that may include adjunctive therapies.
- Holistic Approach to pain Management: Integrate non-pharmacological treatments to support those transitioning from high-dose opioids, thereby maximizing pain relief and minimizing risks.
Editor: As this area of research continues to evolve, what do you see as the next step for clinicians working with high-dose opioid therapy patients?
Dr. Reynolds: Moving forward, more large-scale studies are necessary to determine the specific conditions under which buprenorphine might be beneficial.Additionally, research should focus on the integration of multimodal pain management strategies. Clinicians should also receive training on the complexities of opioid dependence and withdrawal management.Patients, in turn, should engage in open dialogues with their healthcare providers to express concerns and preferences regarding their pain management plans.
Conclusion:
The study urges caution in assuming buprenorphine’s universal efficacy for chronic pain management in high-dose opioid users.
