Therefore, phenytoin does not have a classical half-life like other drugs, since it varies with blood concentration. As the blood concentration drops, the rate at which phenytoin is excreted increases.
Phenytoin has a volume of distribution of 0. Phenytoin pharmacokinetics are significantly affected by a number of other drugs. Phenytoin and phenobarbital are frequently coadministered.
