To address the issues with translatability in drug discovery, many pharmaceutical companies are moving toward examining patient samples to better understand the molecular mechanisms driving disease and identify genetic biomarkers of therapeutic response. DNA microarray is an emerging powerful technological breakthrough that enables the study of global gene expression pattern and sequence variation at genome level 62. Regul Toxicol Pharmacol 2011: 59 (3): 385–390. Clin Pharmacol Ther 2009: 85 (1): 31–35. Today, it forms a crucial part of the scientist’s toolkit and makes a valuable contribution to the field of drug discovery. ABSTRACT: Pharmacogenomics (constitute both branch i.e pharmacology and genetic) is the study of the role of genetics in drug response. Much less work have been done in pharmacodynamic factor causing variation in drug response , but as drug can affect almost any protein in the body , almost every gene may have an effect on how drug vary in their response 6 . Science 1956; 124: 484±485. Trends in Pharmacological Sciences 2001; 22: 298-305.

In some patient the codeine does not get converted into morphine due to the presence of poor metabolizing enzyme CYP4502D6 , hence minimal analgesic effect and pain relief 38. Can J Biochem Physiol 1957; 35: 339±346. More than allelic variant or SNPs are found in candidate gene. FDA works to identify emerging pharmacogenomic issues in science and drug development to develop guidance documents and scientific standards to guide the pharmaceutical industry. Any reduction in the total number of  patient in the phase III study lead to need of large number of patient , more structured phase IV study  in order to identify rare and long term toxicity. Pharmacogenomic, pharmacogenetics, Drugs, Cytochrome, Variants. Indian J Pharmacology 2008: 137-143. The term pharmacogenetic and Pharmacogenomics are used interchangeable as there is no standard definition of the Pharmacogenomics.

Analysis of report adverse event with pharmacogenomics data during development by FDA. Research projects focus on ways to increase efficiency in drug development and apply pharmacogenomics to improve patient care. Before sharing sensitive information, make sure you're on a federal government site. Both the pharmacodynamic and pharmacokinetic factor is responsible for variation in drug response. The human genome has approximately three million SNPs and it is very expensive to screen all the SNPs.
