Extensive variability in CYP3A4 activity is due partly to the large range of substrates effective at inhibiting or inducing the enzyme. Classic examples of 3A4 inducers include the enzyme-inducing antiepileptics phenobarbital, phenytoin, carbamazepine and oxcarbazepine; the non-nucleoside reverse transcriptase inhibitors efavirenz, nivirapine and etravirine; the herbal antidepressant St.
Inspite of accumulation of appreciable pharmacogenomic details and the fact that genotyping of the person should be completed just once, its practical application in regime individual treatment is At this time constrained due to prerequirement of multiple drug precise genotypic screening. Uncomplicated location assessments for some, e.g. G6 PD deficiency are at this time in use.
