Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals diagnosed with moderate to severe opioid use disorder who are treated in the emergency department and meet specific clinical criteria.

Probably not a fit

Patients who are pregnant, have unstable medical or psychiatric conditions, or are currently enrolled in formal addiction treatment may not benefit from this study.

What this trial studies

This clinical trial evaluates the safety and effectiveness of a higher induction dose of buprenorphine (BUP) for patients with opioid use disorder in emergency departments. It consists of two trials: the first compares the safety and tolerability of a 32 mg dose against the standard 12 mg dose, while the second is a pilot study assessing the engagement in addiction treatment within 7 days post-induction. Participants will be monitored closely for any adverse effects during and after the dosing. The study aims to determine if a higher dose can improve patient outcomes and engagement in treatment.

Why it matters

Potential benefit: If successful, this approach could enhance treatment engagement for patients with opioid use disorder, leading to better recovery outcomes.

How similar studies have gone: Other studies have explored buprenorphine dosing, but this specific high-dose approach in emergency settings is relatively novel.
