Evaluation of Drug-Drug Interaction Liability for Buprenorphine Extended-Release Monthly Injection Administered by Subcutaneous Route.

ABSTRACT: Buprenorphine extended-release (BUP-XR) formulation is a once-monthly subcutaneous injection for the treatment of opioid use disorder (OUD). Buprenorphine undergoes extensive cytochrome P450 (CYP) 3A4 metabolism, leading to potential drug-drug interactions (DDIs) as reported for sublingual buprenorphine. Sublingual buprenorphine is subject to first-pass extraction, as a significant proportion of the dose is swallowed. Because subcutaneous administration avoids first-pass extraction, the DDI with CYP3A4 inhibitors is expected to be less than the 2-fold increase reported for the sublingual route. The objective of this analysis was to predict the magnitude of DDI following coadministration of BUP-XR with a strong CYP3A4 inhibitor or inducer using physiologically based pharmacokinetic (PBPK) m
