Irbesartan is a prescription medication used to treat high blood pressure and certain kidney conditions. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs).

High blood pressure (hypertension)

Diabetic nephropathy (kidney disease related to type 2 diabetes)

Reducing the risk of kidney damage progression in certain patients

By lowering blood pressure, irbesartan helps reduce the risk of stroke, heart attack, and kidney complications.

Irbesartan is taken by mouth, usually once daily. It can be taken with or without food.

How Irbesartan Works

Irbesartan blocks the action of a hormone called angiotensin II.

Angiotensin II normally:

Narrows blood vessels

Raises blood pressure

Increases strain on the heart and kidneys

By blocking this hormone:

Blood vessels relax

Blood pressure decreases

Kidney damage progression may slow in certain patients

Irbesartan helps manage high blood pressure and kidney disease but does not cure these conditions. Longterm treatment is often required.
