Losartan is a medication classified as an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten, which helps relax and widen the blood vessels, lowering blood pressure and making it easier for the heart to pump blood

. Uses of Losartan:

• Treats high blood pressure (hypertension) in adults and some children

• Reduces the risk of stroke in people with high blood pressure and left ventricular hypertrophy (enlargement of the heart's left side)

• Treats kidney problems in people with type 2 diabetes and a history of high blood pressure (diabetic nephropathy)

• Used in heart failure and to improve survival after a heart attack

Losartan is available as oral tablets and is prescription-only. It may be used alone or with other medications to control blood pressure

. Important considerations:

• It is not recommended during pregnancy as it can harm the unborn baby

• Common side effects include dizziness and tiredness, but these are usually mild

• Patients should avoid salt substitutes high in potassium while taking losartan due to risk of high potassium levels

• It is often prescribed when patients cannot tolerate ACE inhibitors due to cough

Losartan is sold under brand names such as Cozaar and Arbli and is widely prescribed globally

. In summary, losartan is a widely used ARB medication primarily for managing high blood pressure, protecting kidney function in diabetic patients, and reducing cardiovascular risks such as stroke
