Valsartan is indicated to treat highblood pressure or also known as hypertension. It is a long-term force of theblood against your artery walls is high enough that it may eventually causehealth problems like heart disease. Blood pressure is determined both by theamount of blood your heart pumps. It is also determined by the amount ofresistance to blood flow in your arteries. The more blood your heart pumps andthe narrower your arteries, the higher your blood pressure. You can have thiscondition for years without any symptoms. Hypertension generally develops overyears and it affects nearly everyone eventually.
This medication may also be usedto treat heart failure. This condition is also known as congestive heartfailure. It occurs when your heart muscle does not pump blood as well as itshould. Heart failure can be ongoing or it may start suddenly. Some signs andsymptoms may include:

Valsartan belongs to the class ofmedications called angiotensin receptors blockers (ARBs). This relaxes bloodvessels so that blood can flow more easily. Lowering high blood pressure helpsprevent heart attacks, strokes, and kidney problems. In heart failure, thisdrug lowers the chance of having to go to the hospital for heart failure. Thisis a prescription approved by the Food and Drug Administration (FDA). Valsartanis supplied as an aqueous solution for oral use. It is formulated at aconcentration of 4 mg/mL. Each contains Valsartan as an active ingredient whichis slightly soluble in water and soluble in methanol and ethanol.
Howdoes Valsartan work?
Valsartan works by blockingreceptors in the body known as angiotensin II receptors. This prevents theaction of a hormone called angiotensin II. It is involved in regulating blood pressure andfluid balance. It has two main actions that cause the blood vessels to narrowand the kidneys to retain salt and water. This drug blocks the receptors thatangiotensin II acts on and so prevents its actions. The main result of this isthat the peripheral blood vessels are allowed to widen. It means that there aremore space and less resistance in these blood vessels. This is the mainmechanism by which the pressure in the blood vessels is lowered. Blocking the actions of angiotensin IIalso increases the amount of fluid removed from the blood by the kidneys. This lessensthe quantity of fluid in the blood vessels, which similarly decreases the pressureand resistance in the blood vessels. The combined effect of these changes is tolower the blood pressure.
In treating heart failure, thismedication reduces the workload of the heart. It also has been shown to improvesurvival in people who have these problems following a heart attack.
