Blood Pressure Home > Diovan

Diovan is commonly used to treat conditions related to the cardiovascular system, such as high blood pressure and congestive heart failure, and to help improve survival after a heart attack.

How Does It Work?

Diovan is part of a class of drugs called angiotensin II receptor blockers. As you might expect, it blocks angiotensin II receptors. This decreases the effectiveness of a chemical known as angiotensin II, which normally causes blood vessels to narrow (constrict). By blocking its effects, Diovan causes blood vessels to relax, which can lower blood pressure.
Because of these effects, the medication also increases the efficiency of the heart. This means that the heart does not have to work as hard and more blood can be pumped out to the rest of the body. Both of these effects are helpful for a person with congestive heart failure.
