Low-dose extended-release buprenorphine to make starting treatment easier

Extended release buprenorphine as a novel low-dose induction strategy

NIH-funded research Brigham and Women's Hospital · NIH-11137567

What this research studies

If you have opioid use disorder and come to the emergency department or clinic, researchers will offer a single low-dose extended-release buprenorphine injection as a way to start medication more quickly. The plan is to give a smaller-than-usual buprenorphine dose before withdrawal begins, monitor you for withdrawal and side effects, and collect follow-up information and blood samples over several days. This approach is meant to avoid a multi-day pill titration and the need to keep taking full opioid agonists during induction. The pilot will compare this low-dose injection approach to current initiation methods to see how well people tolerate it and whether it prevents precipitated withdrawal.

Who could benefit from this research

Good fit: Adults with opioid use disorder who want to start buprenorphine treatment in the emergency department or outpatient clinic setting may be eligible.

Not a fit: People who are not trying to start buprenorphine or who have medical contraindications to buprenorphine or injectable treatments may not benefit or be eligible.

Why it matters

Potential benefit: If successful, this could make beginning buprenorphine faster and safer and lower the risk of precipitated withdrawal.

How similar studies have performed: Case reports and small observational series suggest low-dose "micro-dosing" can reduce precipitated withdrawal, but using an early extended-release buprenorphine injection is a newer approach with limited trial data.
