ABSTRACT
Phenytoin (PHT) is an antiepileptic drug with a narrow therapeutic index and large interpatient metabolism variability that is still widely used in underdeveloped countries. The probable main mechanism of action is a membrane sodium channel blockage that is voltage-dependent, which obstructs the positive feedback that underlies the development of seizure activity. However, other mechanisms may contribute to this drug's efficacy too. Herewith, we would like to address some important topics that, together with the study of Lucca et al., could lead to a better comprehension of PHT toxicity.
Keywords: Phenytoin, anticonvulsant, toxicity, intoxication, dilantin
