have been used liberally throughout the book. At the end of every chapter, a
set of questions including numerical have been provided. which are
strategically designed to complement the text of each chapter and test the
student's grasp of the text and their ability to analyze and solve problems. If
this book can help to provide the reader with a clear understanding of the
basic concepts of biopharmaceutics and pharmacokinetics, then we would consider
our object as fulfilled.
We

improvement of drug therapy. We are also indebted to the authors of the various
