In particular, heart failure is associated with chronic activation of RAAS, leading to inappropriate fluid retention, vasoconstriction, and ultimately a further decline in left ventricular function. ARBs have been shown to have a protective effect on the heart by improving cardiac function, reducing afterload, increasing cardiac output and preventing ventricular hypertrophy and remodelling.   By comparison, the angiotensin-converting enzyme inhibitor (ACEI) class of medications (which includes drugs such as [ramipril], [lisinopril], and [perindopril]) inhibit the conversion of angiotensin I to angiotensin II through inhibition of the ACE enzyme. However, this does not prevent the formation of all angiotensin II within the body. The angiotensin II receptor blocker (ARB) family of drugs unique in that it blocks all angiotensin II activity, regardless of where or how it was synthesized.   Valsartan is commonly used for the management of hypertension, heart failure, and Type 2 Diabetes-associated nephropathy, particularly in patients who are unable to tolerate ACE inhibitors. ARBs such as valsartan have been shown in a number of large-scale clinical outcomes trials to improve cardiovascular outcomes including reducing risk of myocardial infarction, stroke, the progression of heart failure, and hospitalization. Valsartan also slows the progression of diabetic nephropathy due to its renoprotective effects. Improvements in chronic kidney disease with valsartan include both clinically and statistically significant decreases in urinary albumin and protein excretion in patients diagnosed with type 2 diabetes and in nondiabetic patients diagnosed with chronic kidney disease.  Valsartan was initially approved in 1996 in Europe for the treatment of hypertension in adults. Shortly after, in 1997, this drug was approved in the United States. Valsartan is generally well-tolerated with a side-effect profile superior to that of other antihypertensive drugs."}]
