This casebook is designed to accompany the Seventh Edition of Textbook of Therapeutics: Drug and Disease Management. It is organized in sections that correspond to the disease and disorder sections of the textbook. Other subjects in the textbook - such as clinical pharmacodynamics, drug interactions, adverse drug reactions, and clinical lab tests and interpretation - are woven into the cases. The casebook provides students a chance to apply the foundations of therapeutics that they have learned in the textbook to simulated clinical situations. There is an Instructor's Guide that accompanies the casebook - available to instructors who adopt the casebook.
