Current Reviews In Pharmacogenomics

Accumulating evidence strongly suggests that genetic polymorphisms in drug-metabolizing enzymes, transporters, receptors, and other drug targets are linked to inter-individual differences in the efficacy and toxicity of many medications. During past two decades, the role of carrier-mediated transport in determining the pharmacokinetics of drugs has becoming increasingly evident with the discovery of genetic variants that affect expression and/or function of a given drug transporter. Drug transporters are expressed at numerous epithelial barriers, such as intestinal epithelial cells, hepatocytes, renal tubular cells and at the blood-brain barrier. Pharmacogenomic studies are rapidly elucidating the inherited nature of differences in pharmacokinetic and pharmacodynamic effects, thereby enhancing drug discovery and providing a stronger scientific basis for optimizing drug therapy on the basis of each patient’s genetic constitution. Hitherto researchers have associated alterations in drug uptake and/or disposition with the presence of genetic polymorphisms. The International Transporter Consortium (ITC) has most recently published the FDA Whitepaper as a report from the FDA Critical Path Initiative-sponsored Drug Transporter Workshop. The pharmaceutical regulatory authorities are now requesting that drug companies integrate genetic information into their clinical trial design.
