Ketamine study for endometriosis pain pulled before it started
NCT ID NCT07182032
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if adding ketamine to standard anesthesia during endometriosis surgery could lower pain afterward. It was designed for adults with chronic pelvic pain and central sensitization, but the trial was withdrawn before enrolling any participants. No results are available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ketamine
- What this could lead to
- If it had worked, this could point toward a way to reduce post-surgery pain for endometriosis patients using a common anesthetic.
- What could go wrong
- The study was withdrawn before any participants were enrolled, so no results are available. Ketamine can cause side effects like hallucinations or nausea, and its benefit for this specific pain type is unproven.
