There is an application of knowledge from diverse fields, like biology, epidemiology, chemistry, chemometrics, physics, mathematics and chemical engineering in the field of pharmaceutical sciences. Pharmacogenomics is an important area of study, which falls under the scope of pharmaceutical sciences. It involves the study of the role of genome in drug response. This book includes some of the vital pieces of work being conducted across the world, on various topics related to pharmacy and pharmaceutical science. It explores all the important aspects of these fields in the present day scenario. The extensive content of this book provides the readers with a thorough understanding of the subject.
