What Is Irbesartan (Avapro)?

Irbesartan is the generic form of the brand-name drug Avapro, which is used to treat high blood pressure.
It's also used to treat kidney disease that's caused by diabetes, as well as heart failure.
The prescription medicine is in a class of drugs known as angiotensin receptor blockers (ARBs), which work by relaxing blood vessels.
Avapro is typically prescribed along with recommendations for healthy lifestyle changes, such as diet and exercise. It's either taken alone, or sometimes combined with other medicines.
The Food and Drug Administration (FDA) approved irbesartan in 1997. It's manufactured by Sanofi-Aventis and Bristol-Myers Squibb Company.
