Losartan Potassium (Presartan 50) 50mg Tablets are used to treat high blood pressure (hypertension) and to protect kidney function in patients with type 2 diabetes. This medication works by blocking the action of a substance that tightens blood vessels, allowing blood to flow more easily and lowering blood pressure. It also helps reduce the risk of stroke and heart failure. Each tablet contains 50mg of Losartan Potassium, and the pack contains 100 tablets, making it a convenient and effective option for long-term management of hypertension and heart health.
