The field of pharmacogenetics is concerned with identifying patients who are more likely to experience adverse effects or an inadequate response to medication. The purpose of pharmacogenomics is to use genetics to help determine the best drugs to treat a particular disease or condition, to optimize their effectiveness, and to minimize any potential side effects.
Pharmacogenomics is the study of how genes affect a person’s response to drugs. Pharmacogenomics determines how the genetic makeup of an individual affects the response to drugs. It deals with the influence of acquired and inherited genetic variation on drug response in patients by correlating gene expression or single-nucleotide polymorphisms with pharmacokinetics.
