Could a Pre-Surgery pill cut morphine use after breast cancer surgery?
NCT ID NCT07320781
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether giving the painkiller tapentadol before breast cancer surgery could lower the amount of morphine needed during and right after the operation. Seventy patients took either tapentadol or a placebo one hour before surgery. Researchers measured morphine use and pain scores for up to four hours after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tapentadol
- What this could lead to
- If it works, this could offer a way to manage pain after breast cancer surgery with less reliance on strong opioids like morphine.
- What could go wrong
- This is a small, completed study with only 70 participants. The results may not apply to everyone, and tapentadol can cause side effects like nausea or dizziness.
