A faster way to start buprenorphine for opioid use disorder involving fentanyl

Rapid outpatient low-dose initiation of buprenorphine for individuals with OUD using fentanyl

NIH-funded research University of Pennsylvania · NIH-11159663

This project is exploring a new, quicker way to begin buprenorphine treatment for people with opioid use disorder who are using fentanyl, aiming to make it easier to start without uncomfortable withdrawal.

What this research studies

We know that buprenorphine is a helpful treatment for opioid use disorder, but starting it can be difficult for those using fentanyl because of severe withdrawal symptoms. This often prevents people from getting the care they need. This project is testing a new 'micro-dose' method where bupuprenorphine is started at very low doses and gradually increased over 10 hours, without requiring you to be in significant withdrawal first. We will compare this new approach to the standard way of starting buprenorphine to see if it is safer, more effective, and more comfortable for patients. Our goal is to find a better way to help more people access life-saving treatment for opioid use disorder.

Who could benefit from this research

Good fit: Ideal candidates are individuals with untreated opioid use disorder who have recently used fentanyl and are looking to start buprenorphine treatment.

Not a fit: Patients who are not using fentanyl or who are already successfully on buprenorphine treatment would not directly benefit from this specific approach.

Why it matters

Potential benefit: If successful, this new approach could make it much easier and more comfortable for individuals using fentanyl to start buprenorphine treatment, potentially leading to more people getting and staying on treatment.

How similar studies have performed: While the standard buprenorphine initiation method is well-established, this specific low-dose 'micro-dosing' approach for fentanyl users in an outpatient setting is a novel strategy being tested for its preliminary efficacy and safety.
