New stomach drug could match standard care for heart patients at bleeding risk
NCT ID NCT04416581
First seen Jan 04, 2026 · Last updated May 16, 2026 · Updated 13 times
Summary
This study compares a new stomach acid reducer (tegoprazan) with a standard one (rabeprazole) in about 3,320 heart patients who take blood thinners and are at high risk for stomach bleeding or ulcers. The goal is to see if the new drug works just as well at preventing serious stomach problems over 12 months. Participants will be randomly assigned to one of the two drugs, and neither they nor their doctors will know which they are taking.
