With the completion of human genomic study, clear relation could now be established between the drug response in relation to a person’s genome. Pharmacogenomics, also known as personalized medicine, uses the person’s genome to determine the dose and dosage regimen, so that therapy could be optimized. As with the techniques like DNA microarray technologies person’s response to a therapy can be predicted and new therapies could be assigned. In the present review, the current technologies, and past significance has been discussed.enPharmacogenomicspersonalized medicineDNA MicroarraArticle
