Can a pill stop Post-Surgery nausea? trial tests oral amisulpride
NCT ID NCT06887621
First seen Sep 09, 2026 · Last updated Sep 10, 2026 · Updated 1 time
Summary
Researchers are testing whether adding a 50 mg oral dose of amisulpride to standard anti-nausea drugs can prevent nausea and vomiting after gynecological surgery. The trial enrolls 276 women at high risk for postoperative nausea and vomiting who are having laparoscopic hysterectomy for benign conditions. Participants receive either oral amisulpride or a placebo one hour before anesthesia, along with intravenous ondansetron and dexamethasone. The goal is to see if the oral drug improves complete response, meaning no nausea, vomiting, or need for rescue medication in the first 24 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
- oral amisulpride, an anti-nausea drug
- What this could lead to
- If it works, oral amisulpride could offer an affordable, painless way to prevent nausea and vomiting after surgery, especially in places where the intravenous form is not available.
- What could go wrong
- This is a Phase 2 trial, so it may not show a clear benefit. Oral drugs can be absorbed differently than IV drugs, and adding a third anti-nausea medicine could cause unexpected side effects.
