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.
What this could mean
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.
