The primary intent of this book is to serve as a rapid review of Pharmacology principles and serve as a study aid to improve performance on Pharmacology written and practical examinations. With this goal in mind, the text is written in rapid-fire, question/answer format. The student receives immediate gratification with a correct answer. Questions themselves often contain a 'pearl' reinforced in association with the question/answer. Additional hooks are often attached to the answer in various forms, including mnemonics, evoked visual imagery, repetition and humour.
