One pill, three medicines: a new hope for stubborn high blood pressure?
NCT ID NCT07784296
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This study looks at how well a single tablet combining three blood pressure medicines—amlodipine, losartan, and chlorthalidone—works in Korean adults with hypertension. Researchers will track changes in blood pressure over six months and note any side effects. The goal is to see if this triple therapy helps patients who are newly diagnosed or not well controlled on one drug.
