Losartan Potassium 50MG
What is Losartan Potassium?
Losartan potassium is a prescription angiotensin II receptor blocker (ARB) used to treat high blood pressure (hypertension), reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy, and slow the progression of kidney disease in people with type 2 diabetes and high blood pressure. It is a widely used first-line medication for blood pressure management. Losartan works by blocking angiotensin II — a hormone that causes blood vessels to narrow — allowing blood vessels to relax and blood pressure to decrease. It is often preferred over ACE inhibitors (like lisinopril) for patients who develop a dry cough from ACE inhibitors. Typical doses range from 25 mg to 100 mg once daily. A licensed provider can prescribe losartan through Rx.com telehealth for blood pressure or kidney protection.Side Effects

What Is Losartan Potassium?
Losartan potassium (brand name: Cozaar) is an oral angiotensin II receptor blocker (ARB) used as a first-line treatment for hypertension and for protecting kidney function in diabetic patients. It is one of the most widely prescribed ARBs in the US and a cornerstone of cardiovascular and renal medicine.
FDA-Approved Uses
- Hypertension — lowers blood pressure in adults and pediatric patients ≥6 years
- Diabetic nephropathy — slows progression of kidney disease in type 2 diabetic patients with high blood pressure and proteinuria
- Stroke risk reduction — in hypertensive patients with left ventricular hypertrophy (LVH)
How Does Losartan Work?
Angiotensin II is a potent vasoconstrictor — it binds to AT1 receptors on blood vessels, causing them to narrow and raising blood pressure. Losartan selectively blocks these AT1 receptors, preventing angiotensin II from raising blood pressure. Unlike ACE inhibitors, ARBs do not cause bradykinin accumulation, so they rarely cause the dry cough that affects ~10–15% of ACE inhibitor users.
Dosage Overview
- Hypertension (adults): 50 mg once daily; may increase to 100 mg once daily
- Diabetic nephropathy: 50 mg once daily, titrated to 100 mg once daily
- Volume-depleted patients: Start at 25 mg once daily
Losartan can be taken with or without food. Also available in a combination tablet with hydrochlorothiazide (HCTZ) for additional blood pressure lowering.
Precautions
ARBs are contraindicated in pregnancy — they can cause fetal harm. Monitor potassium levels, as ARBs can raise them. Avoid in patients with bilateral renal artery stenosis.
