Is Generic Alprazolam XR as Good as Xanax XR?
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 generic versions 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 alprazolam XR versions currently available have an “AB” rating, meaning they are considered equivalent to Xanax XR.
