Brief Summary

According to U.S. Pharmacist® "low-dose aspirin refers to dosages between 81 mg and 325 mg taken every day to prevent heart attacks, strokes, and colon cancer." It has been found through research that low-dose aspirin also decreases the risk of preeclampsia. The American College of Obstetrics and Gynecologists (ACOG) recommends low-dose aspirin (81mg/day) for women at high risk of preeclampsia. However, some researchers report that a dose of aspirin \< 100 mg/day does not seem to decrease the risk of preeclampsia. Another trial studying patients who are at a high risk for preterm preeclampsia, reported a reduction in the occurrence of preeclampsia among patients taking aspirin at a dose of 150 mg. The purpose of this pragmatic randomized study is to compare the difference in the effectiveness of two doses of aspirin: 81 mg versus 162 mg in the prevention of preeclampsia in pregnant women who are at a moderate to high risk for developing preeclampsia.
