Losartan is part of a class of drugs called angiotensin II receptor blockers (ARBs for short). As the name of the drug class implies, losartan 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, losartan causes blood vessels to relax, which can lower blood pressure.
