What is personalized medicine?

Pharmacogenomics is part of a field called personalized medicine — also called individualized or precision medicine — that aims to customize health care, with decisions and treatments tailored to each individual patient in every way possible.

Although genomic testing is still a relatively new development in drug treatment, this field is expanding. Currently, more than 100 drugs have label information regarding pharmacogenomic biomarkers — some measurable or identifiable segment of genetic information that can be used to direct the use of a drug.
