ER pain study pulled before it even started
NCT ID NCT07344350
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to compare an oral morphine tablet to a nasal spray painkiller (sufentanil) for treating severe acute pain in emergency departments. It planned to enroll adults with severe pain, measuring pain levels 30 minutes after treatment. However, the study was withdrawn before any participants were enrolled, so no data was collected.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Morphine sulfate (oral) and sufentanil (intranasal)
- What this could lead to
- If successful, it could show that a simple oral painkiller works as well as a nasal spray for severe pain in the ER.
- What could go wrong
- The study was withdrawn before any patients were enrolled, so no results are available. It is unclear if the approach is safe or effective.
