Pharmacogenomics
The study of how a person's genetic makeup influences their response to medications, including efficacy and risk of adverse reactions. It guides individualized drug selection and dosing, helping clinicians avoid trial-and-error prescribing and reduce harmful side effects.
What is Pharmacogenomics?
Pharmacogenomics is the study of how an individual's genetic makeup affects their response to medications. It looks at how genetic variation influences both how well a drug works and the likelihood of experiencing adverse reactions.
By connecting specific genetic markers to drug response, the field aims to tailor medication choices and doses to the individual. This moves prescribing away from a one-size-fits-all approach.
Why does Pharmacogenomics matter?
Pharmacogenomic insight can spare patients the trial-and-error of finding an effective medication and dose, and can flag people at higher risk of serious side effects before a drug is given. This supports safer, more precise prescribing.
As genetic testing becomes more accessible, pharmacogenomics increasingly informs individualized treatment across many specialties. It represents a practical application of genomic medicine to everyday drug therapy.
