Pharmaceutical innovations are currently guided by a patent system, the patent system protects the innovator of medicines for a period of time. The patent system does not currently stimulate innovation or pricing that provides access to medicine for those who need it the most. It provides for profitable innovation. As of 2014 about $140 Billion is spent on research and development of pharmaceuticals which produces 25-35 new drugs. Technology, which is transforming science, medicine, and research tools has increased the speed at which we can analyze data but we currently still must test the products which is a lengthy process. Differences in the performance of medical care may be due to variation in the introduction and circulation of pharmaceutical innovations.

In the present book, fifteen typical literatures about Pharmaceutical Innovations published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on biochemical pharmacology, clinical pharmacology, drug information, medicinal chemistry and pharmacognosy, molecular pharmacology, etc. We hope this book can demonstrate advances in pharmaceutical innovations as well as give references to the researchers, students and other related people.
