Is this trial a fit for you?
✓Likely a good fit
Pregnant individuals aged 18–45, between 11 and 14 weeks gestation, identified as high risk for preeclampsia.
✕Probably not a fit
Participants with contraindications or who do not develop preeclampsia may not experience a direct benefit.

What this trial studies
This randomized, interventional study compares two aspirin doses (75 mg vs 150 mg) given at bedtime from 11–14 weeks gestation until 36 weeks in pregnant adults aged 18–45 who are at high risk for preeclampsia. The trial aims to determine if the higher dose reduces preeclampsia events and affects birth outcomes such as stillbirth and birth weight. Participants are allocated to one of the two dosing groups and followed through pregnancy with outcome data collected at delivery. Safety criteria exclude individuals with gastritis, coagulation abnormalities, renal disease, very low platelets, fetal malformations, or vaginal bleeding. The sponsor is Medicare Hospital (Pvt) Limited, with a single site in Multan, Punjab Province.
Why it matters
Potential benefit: If successful, higher-dose aspirin could reduce preeclampsia risk and improve birth outcomes for high-risk pregnancies.
How similar studies have gone: Prior studies in aspirin dosing for preeclampsia have shown variable results; this trial tests a specific higher-dose approach in a defined high-risk population.
