The informative purpose of this book is to offer a better understanding of the dual nature of drugs: scientific products that support social healthcare programs, and commercial products that respond to healthcare needs. It also offers science based solutions for bridging the gap between stagnated drug discovery and increased patients expectations, and the gap between high investments in drug research and development and low profit from drug sales. This book was written in response to increasing needs of training healthcare and business students in pharmaceutical medicine. Pharmaceutical scientific and business employees can also use this book for continuous education.
