Designed especially for nursing, medical assistant, and allied health programmes which allow limited time for the study of medications, this updated and classroom-tested pharmacology text provides drug information in an easy-to-use, format that helps build confidence in the study of medications. Calculations are simplified into step-by-step methods, and an index of cross-referenced drugs listed by trade and generic names is included. New features include a new chapter on drugs and geriatrics, new drug tables and illustrations, addition of more than 160 drugs, and new case studies and administrative checklists. The organization of the text eliminates unnecessary detail that may overwhelm or confuse the student. Part I introduces students to the subject of drugs, their sources and uses, as well as dosage calculations that are simplified into two optional, step-by-step processes. Part II organizes the drugs according to their classifications, which are arranged in a logical order. Each classification is described, along with characteristics of typical drugs, purpose, side effects, cautions, and interactions.
