WebSince phenytoin is highly protein-bound and free (unbound) phenytoin is the component producing the pharmacological effect, any factor which changes the protein binding of phenytoin would be expected to alter the free drug levels. As such, interactions with other drugs (drug-drug interactions) or with diseases e.g. renal http://jiwaji.edu/pdf/ecourse/pharmaceutical/PROTEIN%20BINDING%20OF%20DRUGS.pdf

Warfarin is highly protein-bound (>95%) and has a low therapeutic index. Since a low therapeutic index indicates that there is a high risk of toxicity when using the drug, any potential increases in warfarin concentration could be very dangerous and lead to hemorrhage.
