Where is Valsartan used?
Valsartan is used to treat high blood pressure and heart failure. This medicine belongs to the group known as angiotensin receptors blockers (ARBs). This relaxes blood vessels so that blood can flow more easily. This is a prescription approved by the Food and Drug Administration (FDA).
How does Valsartan work?
Valsartan stops angiotensin II receptors which prevent the action of angiotensin II. It is involved in regulating blood pressure and fluid balance. It has two main actions that cause the blood vessels to narrow and the kidneys to retain salt and water. This drug stops the receptors that angiotensin II acts on and so stops its actions. The main effect of this is that the peripheral blood vessels are permitted to expand. It means that there are extra space and less conflict in these blood vessels. Blocking the actions of angiotensin II also increases the amount of fluid removed from the blood by the kidneys. This lessens the quantity of fluid in the blood vessels, which similarly decreases the pressure and resistance in the blood vessels. The combined effect of these changes is to lower blood pressure.
In treating heart failure, this medication reduces the workload of the heart. It also has been shown to improve survival in people who have these problems following a heart attack.
