Aka: Genetic Determinants of Drug Response, Pharmacogenomics, Pharmacogenetics
- Definition
- Genetic polymorphism as it relates to medication response
- Examples
- CYP2D6 Deficiency
- No response to codeine in 10% of patients
- Exaggerated response to Fluoxetine and Nortriptyline
- CYP2C9 Deficiency
