Phenytoin is believed to protect against seizures by causing voltage-dependent block of voltage gated sodium channels. This blocks sustained high frequency repetitive firing of action potentials. This is accomplished by reducing the amplitude of sodium-dependent action potentials through enhancing steady-state inactivation. Sodium channels exist in three main conformations: the rest… WebPhenytoin is a major anticonvulsant drug that is very effective in controlling a wide variety of seizure disorders while impairing neurological function little, if at all. Early work suggested the hypothesis that the drug's effects were due to a selective block of high-frequency neuronal activity.

WebPhenytoin (5,5-diphenylhydantoin), which has been in use for 60 years, is still an important antiepileptic drug. Its primary mechanism of action is modulation of the sustained repetitive firing of neurones by direct inhibition and blockage of voltage-gated sodium channels in the neuronal cell membrane, and by delay of cellular reactivation.
