What is pharmacogenomics. Is it any different from pharmacogenetics? Many will define pharmacogenomics as follows -  the study of how an individual's genetic inheritance affects the body's response to drugs. But that is exactly what pharmacogenetics is. What then is the difference if any? I believe there is a subtle difference although modern pharmacologists would not see one. Pharmacogenetics applies the old models of quantitative genetics, while pharmacogenomics applies the newer models of recombinant DNA. Hence pharmacogenomics is more thorough and delves more into molecular genetics than its older field of pharmacogenetics. It is highly likely though that as research continues in both fields, pharmacogenomics would ultimately swallow up pharmacogenetics.
