Losartan Potassium 25/50/100mg is an angiotensin II receptor blocker (ARB) commonly used to treat high blood pressure (hypertension) and protect the kidneys in patients with type 2 diabetes. By blocking the action of angiotensin II, a hormone that causes blood vessels to constrict, Losartan helps relax and widen the blood vessels, which lowers blood pressure and reduces the strain on the heart. It is also prescribed to manage heart failure and reduce the risk of stroke in certain patients. The medication comes in various strengths, including 25mg, 50mg, and 100mg, allowing for individualized dosing depending on the patient’s condition and response to treatment. Losartan is typically taken once daily, with or without food, and can be used alone or in combination with other antihypertensive medications to achieve optimal blood pressure control.
