Description
Book SynopsisThis 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.
Trade Review"The book provides an excellent introduction for researchers approaching the concept of bioequivalence and is a complete and useful compendium for experienced statisticians." (
Biometrical Journal, April 2009)
"The book provides an important reference providing many worked examples with real data from drug development. Professionals from the harmaceutical industry and regulatory bodies will particularly appreciate the emphasis made on regulatory guidelines." (Statistical Methods in Medical Research, February 2009)
"Bioequivalence Studies in Drug Development: Methods and Applications is an informative, timely, and easy-to-read contribution to bioequivalence and drug-drug/food-drug interaction literature." (Journal of the American Statistical Association, September 2008)
"…those statisticians working in this area of research will find that this book will serve as an excellent reference for their work..." (Journal of Biopharmaceutical Statistics, January 2008)
"This book would be beneficial to both pharmaceutical scientists/researchers and biostatisticians…" (Biometrics, September 2007)
"For anyone interested in any aspect of bioequivalence, the book is a very valuable reference." (International Statistical Review, 2007)
"…my pleasure to review…I would like to add this book to my book collection of pharmaceutical research and development." (Biometrics, September 2007)
