Description
Book SynopsisProvides an introduction to the rapidly expanding field of molecular pharmacology. Adopting a drug target-based, rather than the traditional organ/system based approach, this book reflects the advances and research trend towards molecular based drug design, derived from a detailed understanding of chemical responses in the body.
Trade Review“Overall, it could be the basis of an excellent course for junior pharmacologists in basic science research who need a greater focus on the mechanisms of drug action rather than an encyclopedic survey of clinical drug use.” (Doody’s, 26 July 2013)
