Valsartan is a nonpeptide, orally active, and specific angiotensin ii antagonist acting on the at1 receptor subtype. (amlodipine and valsartan) is indicated for the treatment of hypertension, to lower blood pressure. lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. these benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes, including amlodipine and the arb class to which valsartan principally belongs. there are no controlled trials demonstrating risk reduction with these tablets.
