Diovan (Valsartan)

General Information

Diovan (Valsartan) is for the treatment of heart failure and high blood pressure. This is also used to improve the chance of living longer after a heart attack. In people with heart failure, it may also lower the chance of having to go to the hospital for heart failure. Lowering high blood pressure helps prevent heart attacks, strokes, and kidney problems.


How does Diovan (Valsartan) work?

Diovan (Valsartan) works by blocking receptors in the body known as angiotensin II receptors. This prevents the action of a hormone called angiotensin II. It is involved in regulating blood pressure and fluid causes the blood vessels to narrow and the kidneys to retain salt and water.

This drug blocks the receptors that angiotensin II acts on and it prevents its actions. The main result of this is that the peripheral blood vessels are allowed to widen, that there are more space and less resistance in these blood vessels. This is the main mechanism by which the pressure in the blood vessels is lowered.

By blocking the actions of angiotensin II, it also increases the amount of fluid removed from the blood by the kidneys. This decreases the amount of fluid in the blood vessels, which also lessens the resistance and pressure in the blood vessels.
