"..this is a really extensive and comprehensive book on the drug development process. ...There is very little overlap between chapters and all are written by experts in the field. Hundreds of useful references are included for those wanting to go further. ...Very good value...and essential reading for both the scientist and Ph.D. student. Definately one for the library to stock." --Paul Loadman, University of Bradford, UK for BRITISH JOURNAL OF CANCER, 2002"Well-referenced and indexed...this text would be a useful addition to the clinic, research laboratory and institution library." --P. Parsons, Queensland Institute of Medical Research for CANCER FORUM, 2002
