How Does Cozartan 100mg Work?
Losartan, found in Cozartan, selectively blocks the angiotensin type 1 receptors located on blood vessel walls. This prevents angiotensin from having its vasoconstrictive effect. It promotes vasodilation and lowers blood pressure, reducing strain on the heart and kidneys. This also reduces protein loss from urine in diabetic patients, protecting their kidney function.
