Overview

What is Losartan?

Losartan is an angiotensin II receptor blocker (ARB) used to treat high blood pressure and protect the kidneys in type 2 diabetes with high blood pressure. Unlike ACE inhibitors, losartan does not cause a dry cough, making it a common alternative for patients who cannot tolerate ACE inhibitors. It is taken once or twice daily.

Mechanism

How Does It Work?

AT1 receptor blockade

Losartan selectively blocks the angiotensin II type 1 (AT1) receptor, preventing angiotensin II from exerting its vasoconstrictive and aldosterone-stimulating effects.

Vasodilation

Without AT1 activation, blood vessels relax, peripheral vascular resistance decreases, and blood pressure falls.

Renal protection

By reducing intraglomerular pressure and inhibiting aldosterone-driven sodium retention, losartan slows the progression of diabetic kidney disease.

FAQ

Frequently Asked Questions

Does Losar 25 mg Tablets cause a cough like ACE inhibitors?

No. Losartan is an ARB, not an ACE inhibitor. It does not cause the dry cough associated with ACE inhibitors like lisinopril. This is often why patients are switched to losartan.

How long does Losartan take to lower blood pressure?

Losartan starts working within 6 hours of the first dose. Full blood pressure reduction is typically seen within 3–6 weeks of consistent daily dosing.

Can I take Losar 25 mg Tablets during pregnancy?

No. Losartan is contraindicated in all trimesters. It can cause serious harm to the developing fetus. Tell your doctor immediately if you become pregnant while taking this medicine.

Can Losar 25 mg Tablets protect my kidneys if I have diabetes?

Yes. Losartan is approved for slowing the progression of kidney disease in patients with type 2 diabetes and elevated blood pressure. Regular monitoring of kidney function and potassium levels is recommended.

⚠ BLACK BOX WARNING

Losartan can cause fetal harm. Discontinue as soon as pregnancy is detected. Use during the second and third trimesters can cause injury and death to the developing fetus.

Drug Interactions

Drug / Substance	Effect	Action
