Cozaar is a brand name for losartan, an antihypertensive drug used to treat high blood pressure, among related medical conditions.
How It Works
Cozaar belongs to a group of drugs known as angiotensin II receptor antagonists. Angiotensin II is a substance produced by the body to narrow blood vessels. In healthy individuals, this narrowing helps blood vessels maintain an ideal pressure to make blood flow. But if an individual suffers from a medical condition like heart disease, this narrowing causes abnormally high blood pressure, causing the heart to work harder. Cozaar can therefore block the vessel narrowing agent and cause blood vessels to relax and make blood flow at a lower pressure.
Cozaar is prescribed to treat high blood pressure. Left untreated, high blood pressure can increase the risk of heart failure, kidney failure (especially in patients with diabetes) and stroke.
Cozaar can reduce the risk of these conditions in hypertensive patients and patients with an enlarged heart. Cozaar may also be used to reduce long-term kidney damage in people who have type II diabetes.
Dosage of Cozaar will vary depending on several factors. Your doctor will prescribe you the right dose of Cozaar.
