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… Web1. nov 2015 · Phenytoin was prepared by the reaction of benzil with urea in the presence of sodiumhydroxide.
