Diabetes and aspirin: new study checks if the standard dose is enough
NCT ID NCT05105919
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how well a daily 80 mg dose of enteric-coated aspirin works in 50 adults with type 2 diabetes who have not taken aspirin recently. Researchers measure blood platelet function before and after 7 days of treatment to see if the aspirin fully prevents clotting. The goal is to gather information for a larger future study, not to provide a cure or long-term treatment.
