Which drug stops preterm labor best? new study pits nifedipine against magnesium sulfate

NCT ID NCT05343806

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested two drugs—nifedipine (a pill) and magnesium sulfate (given through a vein)—to see which is better at delaying preterm labor in pregnant women between 32 and 36 weeks. A total of 264 women took part, and the main goal was to see how many avoided giving birth within 48 hours of starting treatment. The hope is that delaying labor gives time for steroids to help the baby's lungs develop, reducing health risks for newborns.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
nifedipine and magnesium sulfate
What this could lead to
If one drug works better, it could help more women delay preterm labor long enough for steroids to mature the baby's lungs, reducing newborn complications.
What could go wrong
This is a single-center trial with 264 participants, so results may not apply to all pregnant women. Both drugs have side effects like low blood pressure or breathing issues.
