Losartan belongs to a group of medicines called angiotensin II receptor antagonists. Angiotensin II is a substance produced in the body that binds to receptors in blood vessels, causing them to narrow. This results in an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, which causes the blood vessels to relax, thereby lowering blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.
