Pharmacogenomics uses genetic differences to predict drug responses, improving treatment efficacy and safety. This review highlights established examples where genetic testing optimizes therapies like antidepressants, chemotherapy, anticoagulants, and statins.
Area of Science:
- Pharmacogenomics
- Clinical Pharmacology
- Genetics
Background:
- Investigates inherited variations in drug metabolism and response.
- Evidence for genetic influences on drug response is growing, but clinical utility is debated.
Observation:
- Discusses established pharmacogenomic applications for routine treatment.
- Focuses on specific gene-drug interactions with clinical relevance.
Findings:
- CYP2D6 genotyping aids antidepressant selection.
- TPMT variant analysis predicts mercaptopurine toxicity.
- VKORC1 and CYP2C9 genotyping optimizes warfarin dosing.
- SLCO1B1 variants identify statin myopathy risk.
Implications:
- Pharmacogenomic testing can personalize drug therapy.
- Improves treatment outcomes and reduces adverse drug reactions.
- Supports the integration of genetic information into clinical practice.
