Economic burden and dosing trends of buprenorphine buccal film and transdermal patch in chronic low back pain.

Exploring prescribing trends and economic burden of chronic low back pain (cLBP) patients prescribed buprenorphine buccal film (Belbuca®) or transdermal patches. In the MarketScan® commercial insurance claims (employees and their spouses/dependents, 2018-2021), the first film or patch prescription date was an index event. The observation covered 6-month pre-index and 12-month post-index periods. Patients were propensity-score matched (708 per cohort). Buprenorphine initiation had stable cost trends in buccal film and increasing trends in transdermal patch cohort. Between-cohort comparisons of healthcare expenditures, cost trends and resource utilization showed significant differences, mostly in favor of buccal film. Buccal film also had higher daily doses and wider dosing range. Buprenorphine film is more cost-effective cLBP treatment with more flexible dosing.
