Figure 1From: Selected pharmacokinetic issues of the use of antiepileptic drugs and parenteral nutrition in critically ill patients Proposed model for phenytoin binding to HSA. The data in this report is consistent with a model in which phenytoin has direct binding at both the warfarin-azapropazone and tamoxifen sites, although it is possible that the competition noted in this study could have been due to negative plus positive allosteric effects between this drug and R-warfarin or cis-clomiphene.
