Abstract
This book covers all the pharmacology you need, from basic science pharmacology and pathophysiology, through to clinical pharmacology to therapeutics, in line with the integrated approach of new medical curricula. The first section covers the basic principles, and the rest is organised by body systems. The book ends with sections on toxicity and prescribing practice.
- Integrates basic science pharmacology, clinical pharmacology and therapeutics
- Brief review of pathophysiology of major diseases
- Case histories and multiple choice questions (and answers)
- Tabular presentation of all common drugs within each class
- Section on further reading
- Kinetics chapter simplified with more practical examples
- Includes more on genetic issues
- Drug tables made more concise to make information more accessible
- Fully updated to reflect current clinical practice
