Description of the active ingredient

Losartan is the active ingredient in medications used to treat high blood pressure (hypertension) and certain types of heart failure. It belongs to a class of drugs known as angiotensin II receptor blockers (ARBs).

Losartan works by blocking the action of angiotensin II, a substance in the body that causes blood vessels to constrict, leading to increased blood pressure. By blocking the effects of angiotensin II, losartan helps to relax blood vessels and lower blood pressure, making it easier for the heart to pump blood efficiently.
