Abstract
Recent population data suggest independence of the genetic polymorphisms in mephenytoin and sparteine/debrisoquine oxidation. We used human liver preparations to test whether mephenytoin competes with sparteine for binding to the genetically variable cytochrome P-450, which mediates metabolism of both sparteine and debrisoquine. Mephenytoin failed to inhibit in vitro sparteine oxidation. This provides biochemical evidence that the polymorphism of sparteine/debrisoquine metabolism is not related to that of mephenytoin.
