FDA Approves New Buprenorphine Treatment Option for Opioid Use Disorder

24 May 2023 • Yesterday, the U.S. Food and Drug Administration approved Brixadi (buprenorphine) extended-release injection for subcutaneous use to treat moderate to severe opioid use disorder. Brixadi is available in two formulations, a weekly injection that can be used in patients who have started treatment with a single dose of a transmucosal buprenorphine product or who are already being treated with buprenorphine, and a monthly version for patients already being treated with buprenorphine.

Buprenorphine is a safe and effective medication for the treatment of OUD. The safety and efficacy of Brixadi were evaluated in a behavioral pharmacology study assessing the ability of two weekly doses of Brixadi to block the subjective effects of opioids, and one randomized, double-blind, active-controlled clinical trial in 428 adults with a diagnosis of moderate-to-severe OUD.

The weekly doses are 8 milligrams (mg), 16 mg, 24 mg, 32 mg; and the monthly doses are 64 mg, 96 mg, 128 mg. The approved weekly formulation in various lower strengths offers a new option for people in recovery who may benefit from a weekly injection to maintain treatment adherence.
