Contents of the pack and other information:
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 leads to an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing blood vessels to relax, which in turn lowers blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.
