How does Losartan work in the body?
Losartan works by blocking the action of a substance in the body called angiotensin II. Angiotensin II is a chemical that narrows blood vessels, which can increase blood pressure and force the heart to work harder. By blocking this substance, Losartan helps to relax and widen blood vessels, reducing blood pressure and improving blood flow. This mechanism of action helps to lower the risk of strokes and heart attacks in patients with hypertension.
In what forms is Losartan available?

It is important to take Losartan exactly as prescribed by your healthcare provider to achieve the best results.
