Using a strong pathophysiology prototype approach to place drugs in context with how they are used therapeutically, this book gives readers a clearer picture of the importance of pharmacology to disease and ultimately to patient care. This holistic perspective to patient care is organized according to the body systems and diseases with complete information on the drug classifications used to treat the diseases. Easy to follow presentation, extensive pedagogical aids enable students to identify key ideas, understand concepts and apply essential components of anatomy, physiology and pathology relevant to drug therapy. The volume comprehensively covers core concepts in pharmacology, pharmacology and the nurse-patient relationship, the nervous system, the cardiovascular and respiratory systems, the immune system, the gastrointestinal system, endocrine and genitourinary systems, the integumentary system, musculoskeletal system, and eyes/ears.
