Avapro is part of a class of drugs called angiotensin II receptor blockers (ARBs for short). As the name implies, Avapro 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 the effects of angiotensin II, Avapro causes blood vessels to relax, which can lower blood pressure.
Avapro has not been approved for use in children.
On occasion, your healthcare provider may recommend Avapro for treating a condition other than those listed in this article. This is called an "off-label" use. At this time, there are no universally accepted off-label Avapro uses.
