Olmesartan is used in the treatment of hypertension and heart failure.
Decreasing high blood pressure lowers the risk of heart attack and stroke.
Chlorthalidone is used in hypertension and oedema.
It treats oedema (fluid overload) associated with heart, liver, kidney or lung disease.
How it works
Olmesartan is an angiotensin receptor blocker (ARB). It works by blocking the hormone angiotensin thereby relaxing blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.
Chlorthalidone is a thiazide diuretic. It lowers blood pressure and fluid retention in edema by removing the extra water and certain electrolytes from the body. Over time it also works by relaxing blood vessels and improving blood flow.
