The first edition of Introduction to Pharmacology has over recent years become a highly influential text among students wishing to acquire a knowledge of pharmacology without having to refer to the larger, more detailed, traditional pharmacology volumes. This revised and updated second edition contains significant new material to bring the reader up-to-date with the latest practices and principles in pharmacology. Exploring the basic principles in both the therapeutic and toxicological aspects of drug use, the book employs contemporary examples of medication, supplemented with an increased number of accurate and easy-to-interpret figures and diagrams. Additionally, Introduction to Pharmacology presents the important concept of understanding the limitations surrounding the drugs that cure, replace physiological inadequacies, or treat symptoms, and which have led to the system of drug classification. The broad scope of the book also encompasses the role of the FDA, drugs in sport, and the use of animals for drug experimentation.
