Oral Bioavailability Assessment: Basics and Strategies for Drug Discovery and Development



Oral Bioavailability Assessment: Basics and Strategies for Drug Discovery and Development

Ayman F. El-Kattan, Mike S. Lee (Series Editor)

ISBN: 978-1-118-91693-3 May 2017 448 Pages



Specifically geared to personnel in the pharmaceutical and biotechnology industries, this book describes the basics and challenges of oral bioavailability – one of the most significant hurdles in drug discovery and development.

•    Describes approaches to assess pharmacokinetics and how drug efflux and uptake transporters impact oral bioavailability
•    Helps readers reduce the failure rate of drug candidates when transitioning from the bench to the clinic during development
•    Explains how preclinical animal models – used in preclinical testing – and in vitro tools translate to humans, which is an underappreciated and complicated area of drug development
•    Includes chapters about pharmacokinetic  modelling, the Biopharmaceutics Drug Disposition Classification System (BDDCS), and the Extended Clearance Classification System (ECCS)
•    Has tutorials for applying strategies to medicinal chemistry practices of drug discovery/development
