LOSANGI - 25 / 50
LOSARTAN-25: Each film-coated tablet contains Losartan Potassium IP 25 mg.
LOSARTAN-50: Each film-coated tablet contains Losartan Potassium IP 50 mg.
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 tighten. This results in an increase in blood pressure. Losartan prevents the effect of angiotensin-II, causing the blood vessels to relax which in turn lowers your blood pressure. Losartan slows the decrease of kidney function in patients with high blood pressure and type II diabetes.
Losartan is indicated to
- treat hypertension in patients older than 6 years,
- reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy
- to treat diabetic nephropathy with elevated serum creatinine and proteinuria in patients with type 2 diabetes and hypertension
