Description
Zestoretic (20/25mg) Tablets combine two proven blood pressure medicines — Lisinopril (20mg), an ACE inhibitor, and Hydrochlorothiazide (25mg), a thiazide diuretic — for effective, long-term control of high blood pressure (hypertension).
This dual-action formulation works by relaxing blood vessels and removing excess salt and water from the body, leading to lower blood pressure, reduced fluid retention, and a decreased workload on the heart.
Zestoretic helps prevent heart attacks, strokes, kidney disease, and other hypertension-related complications when used regularly as prescribed.
