Pharmacogenetics and Pharmacogenomics
Pharmacogenetics is defined by the effects of inherited drugs on genetic substance. It involves the study of DNA damage in living cells in response to the drugs, but it also examines changes in DNA that can be present at birth from one generation to the next. Genetic information, determined chemically in DNA, is maintained, simulated and transmitted to following generations with high fidelity.Pharmacogenomics is the study of science concerned with the identification of the genetic attributes of an individual that lead to variable responses to drugs. Fascinatingly, the science has evolved to also consider patterns of inherited alterations in distinct populations, such as specific ethnicities, that explanation for variability in pharmacotherapeutic responses.
