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 Atacand versions currently available have an "AB" rating, meaning they should be equivalent to Atacand.
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.
