What Is Pharmacogenomics?

Pharmacogenomics is the field of pharmaceutics which works with the results of genetic changes on medicine response in patients by collecting gene expression or single-nucleotide polymorphisms with a medicine's efficacy or toxicity. By doing so, pharmacogenomics purposes to create rational source to positive medicine therapy, with respect to the patients' genotype, to confirm more efficacy with less adverse effects. Such techniques promise the advent of "personalized drugs", in which medicines and drug combinations are optimized for every person's different genetic makeup.
Pharmacogenomics is the complete genome application of pharmacogenetics, which tests the single gene reaction with medicines.

Adverse Drug Reaction. These three easy words send small amount of the fear and horror of a hard negative reaction to a prescribed medicine. But these negative reactions can never exist. A 1998 research report of patients who were admitted in hospital issued in the magazine of the American Medical Association told that in 1994, adverse medicine reactions accounted for greater than 2.2 million severe cases and more then 100,000 deaths, making adverse drug reactions (ADRs) one of the main and basic reasons of hospitalization and death in the United States.
