Pharmacogenetics encompasses the involvement of genes in an individual's response
to drugs. As such, the field covers a vast area including basic drug discovery research,
the genetic basis of pharmacokinetics and pharmacodynamics, new drug development,
patient genetic testing and clinical patient management. Ultimately, the goal of pharmacogenetics
is to predict a patient's genetic response to a specific drug as a means of delivering
the best possible medical treatment. By predicting the drug response of an individual,
it will be possible to increase the success of therapies and reduce the incidence
of adverse side effects.
