Guidance for Industry Bioavailability and Bioequivalence Studies for Orally Administered Drug Products — General Considerations Department of Health and Human Services Food and Drug Administration Center for Drug Evaluation and Research (CDER) March Bioequivalence studies are special type of studies where two drugs or two sets of formulation of the same drug are compared to show that they have nearly equal bioavailability and PK/PD parameters. These studies are often done for generic drugs or when a formulation of a drug is changed during development. Toxicology/safety studies in animals are an integral part of any drug development program, the results of which have a direct impact on both the IND and the NDA. Both bioavailability and bioequivalence concepts are applied to animal toxicology studies to determine and confirm the exposure needs in order to calculate the animal to human safety margins. Bioavailability Studies Two types are there, The first type involves an assessment of the bioavailability of a new drug formulation. The second type study involves a comparison of a test formulation with that of a reference standard dosage form that is proved to have a therapeutic safety and efficacy. To see whether tablet A is bioequivalent to tablet B, the bioavailability rates of the two are compared. 2 . Further Resources. Food and Drug Administation (2002).
