What Is Abisart Used For?

Abisart contains irbesartan, which belongs to a group of medicines called angiotensin-II receptor antagonists. These medications help lower blood pressure and protect kidney function.

Primary Uses

Abisart is used to treat high blood pressure (hypertension). It is also used to treat kidney disease in patients who have both high blood pressure and type 2 diabetes.

How It Works

Angiotensin II is a substance your body produces that causes blood vessels to narrow. Abisart blocks angiotensin-II, which widens your blood vessels and makes it easier for your heart to pump blood throughout your body. This helps lower your blood pressure and slows the decrease of kidney function in patients with high blood pressure and type 2 diabetes.

How to Take Abisart

Your doctor will determine the right dose for you. Take Abisart at about the same time each day to help you remember.

Dosage Instructions

The usual starting dose is one 150 mg tablet once daily. Some patients may need a lower starting dose. Depending on how your blood pressure responds, your daily dose may be increased to 300 mg once daily. For patients with high blood pressure and type 2 diabetes, 300 mg once daily is the preferred maintenance dose. Swallow the tablet whole with a glass of water. You can take it with or without food. The full blood pressure lowering effect should be reached about 4 to 6 weeks after starting treatment.

What If You Miss a Dose?

If you miss a dose and it’s almost time for your next dose, skip the missed dose and take your next dose at the regular time. If it’s not almost time for your next dose, take it as soon as you remember, then go back to your normal schedule. Do not take a double dose to make up for the missed dose.

Important: Never take a double dose to make up for a missed dose. Continue taking Abisart until your doctor tells you to stop.
