💊 How does losartan work?

Losartan is an angiotensin II receptor blocker (ARB).

It works by blocking the AT1 receptor, which prevents angiotensin II from exerting its usual effects.

That leads to:

🩸 Less vasoconstriction
💧 Less sodium and water retention
📉 Lower blood pressure
❤️ Reduced pressure load on the heart

In simple terms:

Losartan blocks angiotensin II → blood vessels relax → blood pressure falls.

It is commonly used in conditions such as hypertension, and in some patients it may also help protect the kidneys and reduce cardiovascular strain.

💊 How does furosemide work?

Furosemide is a loop diuretic.

It blocks sodium reabsorption in the thick ascending limb of the loop of Henle.

As more sodium stays in the nephron, water follows → more urine is produced.

That helps reduce:

* edema
* fluid overload
* blood pressure in some patients
