Avapro

Avapro is a medication used to treat diabetic nephropathy and high blood pressure. It works by blocking angiotensin II receptors, which causes blood vessels to relax. Avapro comes in tablet form and is available in a number of strengths, including 75 mg, 150 mg, and 300 mg. Commonly reported side effects include fatigue, heartburn, or dizziness.

What Is Avapro?

Avapro® (irbesartan) is a prescription medicine that has been licensed to treat several conditions related to the heart and blood vessels. It is part of a class of drugs called angiotensin II receptor blockers, or ARBs for short.
 

Who Makes It?

Avapro is manufactured and sold through a partnership between two pharmaceutical companies -- Bristol-Myers Squibb Company and sanofi-aventis.
 

What Is Avapro Used For?

Uses of Avapro include:
 
However, this medication is not a cure for high blood pressure or diabetic nephropathy, nor has it been approved for use in children.

How Does It Work?

Avapro is part of a class of drugs called angiotensin II receptor blockers.
 As the name implies, the drug blocks angiotensin II receptors. This decreases the effectiveness of a chemical known as angiotensin II, which normally causes blood vessels to narrow (constrict). By blocking the effects of angiotensin II, Avapro causes blood vessels to relax, which can lower blood pressure.
 

Effects of Avapro

A blood pressure reading consists of two numbers -- for example, 120/80. The top number is known as the systolic blood pressure, and the bottom number is the diastolic blood pressure. During clinical studies in people taking Avapro, systolic blood pressure decreased on average by 8 to 12 mmHg (millimeters of mercury) and diastolic blood pressure decreased by 5 to 8 mmHg on average. Certain factors, such as dosage, affected how much the blood pressure dropped.
 
By lowering blood pressure, Avapro can decrease the risks that are often seen with long-term high blood pressure (see Effects of High Blood Pressure).
 
This medication has also been shown to slow down the progression of diabetic nephropathy.
 

When and How Do I Take It?

General considerations for when and how to take Avapro include the following:
 
  • The medication comes in tablet form and is taken once a day.
