Area of Science:

  • Pharmacogenetics
  • Genomics
  • Drug Metabolism

Context:

  • Pharmacogenetics has studied genetic influences on drug response for 50 years.
  • The Human Genome Project and DNA chip technology accelerate personalized medicine.
  • Adverse drug reactions cause significant hospital admissions and morbidity.

Purpose:

  • To review the principles of pharmacogenetics for clinical implementation.
  • Focus on liver CYP450 enzyme polymorphisms (CYP2D6, CYP2C19).
  • Examine human genome diversity and genetic polymorphism of drug targets.

Summary:

  • Pharmacogenetics links genetic data to tailored pharmacotherapy.
  • Focus on CYP450 enzymes (CYP2D6, CYP2C19) for clinical application.
  • Highlights variability in drug efficacy due to genetic polymorphisms.
