Small study aims to pinpoint safer oxytocin dose for C-Section moms
NCT ID NCT05290129
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests different doses of oxytocin, a drug that helps the uterus contract after childbirth, to find the lowest effective dose for women having a C-section after labor. The goal is to prevent postpartum hemorrhage (heavy bleeding) while minimizing side effects. Forty women will be enrolled, and each woman's dose will be adjusted based on the previous participant's response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Oxytocin (Pitocin)
- What this could lead to
- If successful, this could identify a safer, lower dose of oxytocin to prevent dangerous bleeding after C-section, reducing side effects while still protecting mothers.
- What could go wrong
- This is a very small, early dose-finding study (40 participants) and may not apply to all women. The results are preliminary and need confirmation in larger trials.
