Valsartan is an angiotensin II receptor blocker (ARB) that may be used to treat high blood pressure or reduce the risk of being admitted to the hospital if you have heart failure. Specifically, valsartan is FDA-approved to:
Lower high blood pressure in adults and children aged 1 year and older, either alone or in combination with other blood pressure medicines Decrease the need for hospitalization because of heart failure in adults with heart failure Increase the chance of living longer after a heart attack (myocardial infarction) in adults with certain types of heart failure.
Valsartan should not be used to treat high blood pressure in children less than 1 year of age and it is not known if it is safe and effective in children with certain kidney problems.
Valsartan works by blocking angiotensin II, a powerful blood pressure regulator that narrows blood vessels (vasoconstriction), affects the production and release of aldosterone, stimulates the heart, and promotes sodium reabsorption by the kidneys. Valsartan blocks angiotensin II from binding to the AT 1 receptor in many tissues such as blood vessel smooth muscle and the adrenal gland, lowering blood pressure.
Valsartan was FDA-approved on December 23, 1996, as the brand name Diovan. Generic valsartan has been approved since June 2014.
