Factors to guide the use of extended-release buprenorphine formulations for specific patient populations

Opioid agonist therapy is first line in the management of opioid use disorder (OUD). Many guidelines support buprenorphine as the optimal treatment due to its preferred safety profile. Extended-release buprenorphine (BUP-XR) is a weekly or monthly subcutaneously administered formulation of buprenorphine. Emerging research has explored the use of BUP-XR in a variety of patient populations to guide clinicians in determining which patients may or may not benefit from BUP-XR. We conducted a literature review in Medline, PsycInfo and Embase to capture the literature to date on BUP-XR. Abstracts were reviewed, and papers which guided selection of individuals who would or would not benefit from BUP-XR were included. Our search returned 359 articles, and 31 met inclusion criteria. Special populations who may benefit from BUP-XR include individuals experiencing homelessness, incarceration, and medical or psychiatric comorbidity, while caution should be used around pregnancy. Patient preference and patient-centered outcomes were recurring considerations to guide the selection of BUP-XR. Extended-release buprenorphine formulations represent a relatively new tool for managing OUD and may specifically benefit patients undergoing transitions in care. Further research on the comparative effectiveness of extended-release versus daily-dosing formulations and in other populations of interest is needed.
