Guide on Bioequivalence Studies with Pharmacokinetic Endpoints
FDA has release a revised draft guidance entitled Bioequivalence Studies with Pharmacokinetic Endpoints for Drugs Submitted Under an ANDA. The document provides recommendations on how to meet the bioequivalence (BE) requirements set forth in the Federal Food, Drug, and Cosmetic (FD&C) Act and FDA regulations. It is applicable to dosage forms intended for oral administration and to non-orally administered drug products in which reliance on systemic exposure measures is suitable for establishing BE (e.g., transdermal delivery systems and certain rectal and nasal drug products). Additionally, the guidance is applicable to applicants planning BE studies intended to be conducted during the post-approval period for changes to a drug product approved under an ANDA.
