Short description
This book provides an overview of available methods for bioequivalence studies, adopting a practical approach via numerous examples using real data. All medical/pharmacokinetic background is provided, so that the book is suitable for both medical practitioners/pharmaceutical scientists, and biometricians. The book includes recent methodology, notably in studies of population and individual bioequivalence, and includes discussion of regulatory issues, and how they differ worldwide.
