All the fields of study dealing with the action, design, delivery and disposition of pharmaceutical drugs come under pharmaceutical sciences. They involve the application of knowledge from other branches of science including chemistry, physics, biology, epidemiology, chemometrics, chemical engineering, etc. Pharmacology, pharmaceutical chemistry, pharmaceutics and pharmacognosy are four main branches, which fall under the scope of pharmaceutical science. Pharmacology is further subdivided into some specific fields such as pharmacodynamics, pharmacokinetics, pharmaceutical toxicology and pharmacogenomics. It is mainly concerned with drug actions and their effects. This book attempts to understand the multiple branches that fall under the discipline of pharmaceutical sciences and how such concepts have practical applications. The various advancements in this field are glanced at and their applications as well as ramifications are looked at in detail. For all those who are interested in pharmaceutical sciences, this book can prove to be an essential guide.
