Losan 50 mg contains Losartan Potassium, a selective Angiotensin II Receptor Blocker (ARB), which works by blocking the action of angiotensin II, a hormone responsible for constricting blood vessels. By preventing this action, Losartan helps relax and widen blood vessels, thus reducing blood pressure and easing the workload on the heart.
This medication is commonly prescribed to manage high blood pressure (hypertension), reduce the risk of stroke in hypertensive patients with left ventricular hypertrophy, and to protect kidney function in patients with type 2 diabetes and hypertension.
