Irbesartan

What is Irbesartan?

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).

Irbesartan is commonly prescribed for:

• 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.

Available Forms and Strengths

Irbesartan is available as:

• Oral tablets

Common strengths include:

Irbesartan 150mg

Irbesartan 300mg

Availability may vary by country.

What is the Recommended Dosage of Irbesartan?

The appropriate dose depends on:

• The condition being treated
• Blood pressure levels
• Kidney function
• Age
• Other medications being taken

Patients with kidney problems or those taking diuretics may require careful dose adjustment.

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

Dosing must follow instructions from a licensed medical specialist. Do not adjust the dose without medical guidance.

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.
