Balanced, readable, and authoritative, this volume provides a well-tested introduction to basic pharmacology for students of medicine, dentistry, pharmacy, and allied health fields. The fourth edition includes new chapters on drug-induced carcinogenesis and teratogenesis, adverse drug reactions, perinatal pharmacology, geriatric pharmacology, and behavioral pharmacology. The material on clincal pharamacology and therapeutics, formerly a separate section, has been integrated into various chapters throughout the text, where it amplifies and illustrates the basic pharamcological concepts. With over 70 chapters, 46 contributors, an improved format and many new illustrations, the new edition provides a lucid, step-by-step introduction to medical pharmacology.
