Generic Irbesartan

It is now possible to buy irbesartan in generic form. The generic versions come in three strengths and are made by a number of manufacturers. All of the generic forms of irbesartan have been assigned an "AB" rating by the FDA. This means they are considered equivalent to the brand-name version; however, they are allowed to contain different inactive ingredients.

Generic Irbesartan: An Overview

Irbesartan (Avapro®) is a prescription medication that has been licensed to treat high blood pressure (hypertension) and diabetic nephropathy. It is part of a class of drugs called angiotensin II receptor blockers (ARBs for short). As the name implies, irbesartan 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, irbesartan causes blood vessels to relax, which can lower blood pressure.
Brand-name Avapro is manufactured and sold through a partnership between two pharmaceutical companies -- Bristol-Myers Squibb Company and sanofi-aventis. However, the first patent for this medication has expired, and it is now available in generic form, too.

Availability of Generic Avapro

Generic Avapro tablets are available in the three following strengths (just like brand-name Avapro):
  • Irbesartan 75 mg
  • Irbesartan 150 mg
  • Irbesartan 300 mg.
Generic Avapro is made by various manufacturers, including but not limited to:
  • Mylan Pharmaceuticals, Inc.
  • Macleods Pharma
  • Teva Pharmaceutical Industries
  • Winthrop U.S.

Is Generic Irbesartan as Good as Avapro?

All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns a rating to each one.
An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic versions of Avapro currently available have an "AB" rating, meaning they should be equivalent to Avapro.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
