Original Abstract of the Article

Major Research Findings

Clinical studies demonstrate that buprenorphine is a pharmacological agent that can be used for the treatment of various types of painful conditions. 8 This study investigated the efficacy of 5 different types of buprenorphine formulations in the chronic pain population. 8 Of the 25 studies reviewed, a total of 14 studies demonstrated clinically significant benefit with buprenorphine in the management of chronic pain. 8 A transdermal buprenorphine formulation is an effective analgesic in patients with chronic pain. 8 Buccal buprenorphine is also a promising formulation based on the limited number of studies. 8

A case report demonstrated a successful transition from a full opioid agonist to buccal buprenorphine in a patient with chronic pain. 4 The patient was able to successfully taper off the full opioid agonist while gradually increasing buprenorphine, without experiencing withdrawal symptoms. 4 This approach resulted in improved quality of life and function for the patient. 4

Buprenorphine buccal film (BBF) is approved by the US Food and Drug Administration for use in patients with chronic pain severe enough to require daily, around-the-clock, long-term opioid treatment. 2 A Phase I placebo-controlled trial comparing BBF with oral oxycodone hydrochloride found that BBF had a ceiling effect on respiratory depression, unlike full μ-opioid receptor agonists. 2

A new BioErodible MucoAdhesive (BEMA®) delivery system for buprenorphine has been developed to treat chronic low back pain (cLBP). 5 The buccal buprenorphine (BBUP) film developed for this product (Belbuca™) allows for rapid delivery and titration over a greater range of doses than was previously available with transdermal buprenorphine systems. 5 In clinical studies, BBUP was shown to effectively reduce pain associated with cLBP at 12 weeks with good tolerability. 5 Chronic pain patients using other opioids can be successfully rotated to BBUP without risk of withdrawal symptoms or inadequate analgesia. 5

An animal study evaluated the analgesic effect and absorption of buprenorphine after buccal administration in cats with oral disease. 9 The results demonstrated that buccal administration of buprenorphine produced an analgesic effect in cats with gingivostomatitis. 9

Benefits and Risks

Benefit Summary

Buprenorphine may be a clinically significant benefit in the management of chronic pain. 8 Transdermal buprenorphine has been shown to be an effective analgesic in patients with chronic pain. 8 Buccal buprenorphine is also a promising formulation. 8 Buprenorphine may be a safe and effective alternative to traditional opioids for many patients with chronic pain. 3 Buprenorphine has been shown to have a ceiling effect on respiratory depression, unlike full μ-opioid receptor agonists. 2 Buprenorphine buccal film allows for rapid delivery and titration over a greater range of doses than was previously available with transdermal buprenorphine systems. 5 Buprenorphine may provide effective analgesia while producing less adverse effects. 6

Risk Summary

Buprenorphine can cause side effects such as nausea, constipation, and vomiting. 5 Buprenorphine is a Schedule III opioid, which means it has the potential for abuse and addiction. 1

Comparison Across Studies

Commonalities

Many studies suggest that buprenorphine may be effective in managing chronic pain. 8 Many studies reported good tolerability of buprenorphine, with no serious adverse effects. 8

Differences

Studies vary in their buprenorphine formulations, study designs, and types of chronic pain investigated. 8 Some studies specifically investigated the efficacy of buprenorphine for certain types of chronic pain, while others looked at a broader range of conditions. 8

Consistency and Contradictions in Results

The evidence suggests that buprenorphine may be an effective option for managing chronic pain. 8 However, there may be differences in effectiveness and safety depending on the buprenorphine formulation and administration method. 8 Further research is needed to determine the optimal formulation and administration method for using buprenorphine in chronic pain management. 8

Considerations for Real-World Application

Buprenorphine may be effective in managing chronic pain, but it is essential to use it as directed by a doctor. 8 Buprenorphine is a Schedule III opioid and has the potential for abuse and addiction. 1 Talk to your doctor before taking buprenorphine. 8

Limitations of Current Research

This review examined a limited number of studies to evaluate the efficacy and safety of buprenorphine. 8 Furthermore, many studies focused on patients with specific types of chronic pain. 8 Additional research is needed to investigate how buprenorphine affects other types of chronic pain. 8

Future Research Directions

Future studies should investigate the efficacy of buprenorphine for different types of chronic pain. 8 Further research is also needed to determine the optimal dosage and administration method for buprenorphine. 8

Conclusion

Buprenorphine may be a promising medication for managing chronic pain. 8 However, it is crucial to use it as directed by a doctor since buprenorphine is a Schedule III opioid with the potential for abuse and addiction. 1 Talk to your doctor before taking buprenorphine. 8
