Guidance Issuing OfficeCenter for Veterinary Medicine
This guidance describes an approach to satisfy the requirements for the completion of the Bioequivalence technical section for generic Type A medicated articles (TAMAs) containing poorly soluble, locally acting, active pharmaceutical ingredients (APIs) that have little to no systemic absorption, and for which blood level studies are not considered appropriate to demonstrate product bioequivalence. The suggested approach described in this guidance uses a combination of in vitro and in vivo data to support a determination of bioequivalence to address the unique challenges associated with demonstrating bioequivalence of TAMAs containing poorly soluble, locally acting APIs that have little to no systemic absorption.
