Calcium levels may boost key drug for postpartum bleeding

NCT ID NCT06930391

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This lab study uses uterine tissue from 40 women having planned C-sections to see if calcium levels change how well carbetocin (a drug that helps the uterus contract) works. The goal is to find the best calcium level to improve carbetocin's effect, which could help prevent or treat severe bleeding after childbirth. It's an early, ex-vivo study, so results are not yet ready for patient care.

Active substance
carbetocin and calcium chloride
What this could lead to
If it works, this could guide doctors on using calcium to make carbetocin more effective for preventing or treating severe bleeding after childbirth.
What could go wrong
This is a very early lab study using tissue samples, not patients. Results may not translate to real-world care, and the sample size is small (40 samples).
