Heartburn drug may shield seniors from bleeding while on blood thinners
NCT ID NCT06393868
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether omeprazole, a common heartburn drug, can reduce gastrointestinal bleeding in adults 65 and older who take blood thinners for blood clots. Researchers will enroll 360 participants to see if a larger trial is feasible. The study focuses on recruitment and adherence, not yet on proving the drug works.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Omeprazole (a proton pump inhibitor)
What this could lead to
If this pilot succeeds, it could lead to a larger study that may show omeprazole helps prevent stomach bleeding in older adults taking blood thinners for blood clots.
What could go wrong
This is a small pilot study to test feasibility, not effectiveness. It may not prove omeprazole works, and results may not apply to all patients. Omeprazole can have side effects like headache or diarrhea.
