What is Valsartan

Valsartan is a nonpeptide triazole-derived antagonist of angiotensin (AT) II receptor with antihypertensive properties. It was patented in 1990 and came into medical use in 1996. It is available as a generic medication. It works by relaxing blood vessels so that blood can flow more easily. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

Valsartan is active orally and is taken by mouth. Valsartan/hydrochlorothiazide, valsartan/amlodipine, valsartan/amlodipine/hydrochlorothiazide, and valsartan/sacubitril are some of the available combinations for medical use.
