The pharmacokinetics and pharmacodynamics of valsartan in the post-myocardial infarction population.

PMID 22998368


The most common risk factors for heart failure are hypertension and myocardial infarction. Angiotensin receptor blockers (ARBs) attenuate the deleterious effects of angiotensin II. Valsartan is a once or twice daily ARB that is FDA-approved for hypertension, LV dysfunction post-myocardial infarction and congestive heart failure as both an adjunct in ACE-inhibitor tolerant, and alternative in ACE-I intolerant patients. This article presents a comprehensive review of the literature regarding the pharmacokinetics and pharmacodynamics of valsartan, with particular attention paid to the post-myocardial infarction population. Valsartan is a safe, well-tolerated and readily titratable ARB. In addition to its vasodilatory effects there are pleotropic effects associated with the ARB such as modulation of a number of neurohormonal regulators, cytokines and small molecules. Given the clear evidence-based benefits above and beyond its hypertensive properties, it has the potential, if priced appropriately, to grow in its impact as a pharmacotherapeutic long after its patent expires.
