Benicar is part of a class of drugs called angiotensin II receptor blockers, or ARBs for short. As the name implies, this medication blocks angiotensin II receptors. This action decreases the effectiveness of a chemical known as angiotensin II, which normally causes blood vessels to narrow (constrict). As a result, Benicar causes blood vessels to relax, which can lower blood pressure.
