This advanced pharmacotherapeutics text for nurse practitioners and physician assistants offers guidelines on prescribing drugs for over 50 common diseases and disorders. The book is organized by disorder rather than drug class and includes algorithms and case studies that illustrate critical thinking aspects of prescribing, such as drug selection, lifespan considerations, therapeutic drug monitoring, adverse reactions, unexpected outcomes, and when to change therapy. This Second Edition has new chapters on oncologic disorders and complementary and alternative medicines. Improved case studies reflect more realistic practice issues in decision-making. Additional areas addressed include food-drug interactions, dietary considerations, and concerns regarding geriatric patients.
