Contents of the pack
Losartan belongs to a group of medicines known as angiotensin II receptor antagonists.
Angiotensin II is a substance produced in the body which binds to receptors in blood vessels, causing them to narrow. This narrowing leads to an increase in blood pressure. Losartan prevents the binding of angiotensin II to these receptors, resulting in the relaxation of blood vessels, which in turn lowers blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.

In the treatment of heart failure, losartan is usually combined with a diuretic (a medicine that increases the amount of water that passes through your kidneys) and/or digitalis (a medicine that helps your heart beat stronger and more efficiently) and/or a beta-blocker.
