Methods of rapid screening of cytochrome CYP2C19 status using mephenytoin

摘要

Mammalian subjects may be phenotyped as poor or extensive metabolizers with respect to CYP2C19 by measuring the ratio of R and S mephenytoin or S-mephenytoin to S-4-hydroxymephenytoin produced from racemic mephenytoin in urine, saliva or plasma samples.
