Organized to reflect the syllabi in many pharmacology courses and in integrated curricula, Basic & Clinical Pharmacology, Fourteenth Edition covers the important concepts students need to know about the science of pharmacology and its application to clinical practice. Selection of the subject matter and order of its presentation are based on the authors’ many years’ experience in teaching this material to thousands of medical, pharmacy, dental, podiatry, nursing, and other health science students. To be as clinically relevant as possible, the book includes sections that specifically address the clinical choice and use of drugs in patients and the monitoring of their effects, and case studies that introduce clinical problems in many chapters. Presented in full color and enhanced by more than three hundred illustrations (many new to this edition), Basic & Clinical Pharmacology features numerous summary tables and diagrams that encapsulate important information.
