New Under-the-Tongue painkiller could speed up surgery recovery
NCT ID NCT07624006
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares a new under-the-tongue painkiller (sublingual sufentanil) to standard morphine pills for managing pain after surgery. The goal is to see if the new drug helps patients recover their health faster. About 1150 adults having surgery will take part, receiving either the new drug or morphine as needed for up to three days after their operation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sublingual sufentanil (Dzuveo)
- What this could lead to
- If it works, this could offer a faster-acting pain relief option after surgery, potentially improving recovery quality.
- What could go wrong
- This is a Phase 4 trial, so the drug is already approved. However, it may not prove significantly better than morphine, and side effects like nausea or dizziness are possible.
