Losartan Potassium (Saphlor 50) 50mg Film Coated Tablets are used to treat high blood pressure (hypertension) and help protect the kidneys in people with diabetes. They work by blocking the action of angiotensin II, a substance that narrows blood vessels, thus helping to relax and widen the blood vessels, which lowers blood pressure. Each pack contains 100 tablets, making it a convenient option for long-term blood pressure management.
