Valsartan, sold under the brand name Diovan among others, is a medication used to treat high blood pressure, heart failure, and diabetic kidney disease. [8] It belongs to a class of medications referred to as angiotensin II receptor blockers (ARBs). It is a reasonable initial treatment for high blood pressure. [8] It is taken by mouth. [8]
Sacubitril/valsartan, sold under the brand name Entresto among others, is a fixed-dose combination medication for use in heart failure. ... chronic kidney disease, ...
Their main uses are in the treatment of hypertension (high blood pressure), diabetic nephropathy (kidney damage due to diabetes) and congestive heart failure. They selectively block the activation of the AT 1 receptor , preventing the binding of angiotensin II compared to ACE inhibitors .
Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%, and can reduce the likelihood of dementia ...
An optimal blood pressure control is essential to prevent target-organ damage associated with complications of hypertension such as heart failure, ischemic heart diseases, stroke, and renal failure, ultimately reducing the risk of premature mortality. [2] Antihypertensives are classified by different mechanisms or sites of action.
Most of the known actions of Ang II are mediated through the AT 1 receptors, for example vasoconstriction, aldosterone release, renal sodium reabsorption and vasopressin secretion. The AT 2 receptor also takes part in regulation of blood pressure and renal function but mediates antagonistic effects compared to the AT 1 receptor. [8] [10] [11] [12]
The use of valsartan in pregnancy is avoided due to the potential risk of fetal toxicity. [11] The U.S. Food and Drug Administration has a black box warning for valsartan/hydrochlorothiazide use during pregnancy. [2] The use of hydrochlorothiazide is avoided in those with anuria or severe kidney disease. [12]
The "vaptan" drugs act by directly blocking the action of vasopressin at its receptors (V 1A, V 1B and V 2).These receptors have a variety of functions, with the V 1A and V 2 receptors are expressed peripherally and involved in the modulation of blood pressure and kidney function respectively, while the V 1A and V 1B receptors are expressed in the central nervous system.
