The patient with more than three or more functional copies of CYP450 2D6 are classified as ultra rapidly metabolizers, which rapidly convert codeine to morphine and produces morphine toxicity even at very low dose. But the genomic studies reduces the sample size than that of the current resource of any single pharmaceutical company or an academic laboratory. Possible implication of pharmacogenetic/ Pharmacogenomics for drug development: The use of pharmacogenetic and Pharmacogenomics principle in the drug development process has reduced the drug dose, increase the rate of absorption and drug targeting is increased remarkably.
