AVAPRO (irbesartan)

Angiotensin 2 Receptor Antagonists
Cardiovascular Approved 1997-09-30

Avapro helps patients with high blood pressure by lowering their blood pressure levels. This reduction in pressure is used to decrease the risk of serious cardiovascular events, such as strokes and heart attacks. Additionally, it treats diabetic kidney disease in patients who have type 2 diabetes along with high blood pressure and specific kidney markers like proteinuria.

How AVAPRO Works

This medication works by selectively blocking the binding of angiotensin II to the AT1 receptors found in tissues like the adrenal glands and vascular smooth muscle. By preventing this hormone from binding, the drug stops the processes that cause blood vessels to constrict and the body to secrete aldosterone. This blockade results in lowered blood pressure and helps manage sodium balance without affecting other cardiovascular regulators like ACE.
