Higher aspirin dose may better prevent dangerous pregnancy condition
NCT ID NCT07041385
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether 150 mg of aspirin works better than 75 mg to prevent preeclampsia in pregnant women at high risk. About 340 women aged 18-30 with a single pregnancy will take aspirin nightly from early pregnancy. The main goal is to see which dose reduces the chance of developing preeclampsia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- aspirin
- What this could lead to
- If it works, this could show that a higher dose of aspirin is better at preventing preeclampsia in high-risk pregnant women, potentially reducing serious complications.
- What could go wrong
- This is a relatively small, single-center trial that hasn't started yet. The difference between doses may be small, and results may not apply to all populations.
