ClinicalTrials.gov ID: NCT06468202
What this study is testing
What is Aspirin 81 mg?
This is an investigational low-dose aspirin being studied to see if it helps prevent high blood pressure problems during pregnancy. It is designed to reduce the formation of blood clots by affecting how platelets stick together.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The trial wants to see if the higher dose of aspirin better stops hypertension and related complications during pregnancy, and to learn what helps people stick to the medication.
- Who it's for
- Women who are pregnant or planning pregnancy and are at risk for high blood pressure problems during pregnancy.
- What's involved
- Participants will take either 162 mg or 81 mg of aspirin each day, and will have regular check‑ups and blood pressure checks to monitor their health.
- Time commitment
- The study lasts through the pregnancy, with visits at the start and at regular intervals to track blood pressure and any side effects.
- Phase 4: studies an already-approved treatment
- Which group you join is decided by chance.
