Emerging role of pharmacogenetic in organ transplantation

The currently used immunosuppressive drugs have a narrow therapeutic index which required to individualize the dose regimen for different recipients. Pharmacogenetic is the use of genetic screening to prevent metabolic responses to different immunosuppressive drugs. Since the oxidative enzymes cytochrome P450 CYP3A and the drug efflux pump P-glycoprotein (P-gp) play a pivotal role in immunosuppressive drugs metabolism, pharmacogenetic studies have been mainly focused on these two enzymes. This would provide an important aid toward drug regimen individualization during the post-transplant therapy and has potential to improve graft outcome.
