Human Drug Metabolism
An Introduction
Second edition
by Michael D. Coleman

Human Drug Metabolism provides an accessible introduction to the subject and will be particularly invaluable to those who already have some understanding of the life sciences. The new edition focuses only on essential chemical detail and includes patient case histories to illustrate the clinical consequences of changes in drug metabolism and its impact on patient welfare.

Topics covered include:

  • Toxicity and drug concentration
  • How metabolizing systems operate and how they impact upon drug concentration, both under drug pressure and during inhibition
  • Factors affecting drug metabolism
  • Age and diet are discussed
  • How metabolism can lead to toxicity
  • Role of drug metabolism in the commercial development of therapeutic agents as well as the pharmacology of some illicit drugs


Part 1: Introduction

  • Therapeutic window
  • Consequences of drug concentration changes
  • Clearance

Part 2: Drug Biotransformational Systems – Origins and Aims

  • Biotransforming enzymes
  • Threat of lipophilic hydrocarbons
