The mechanism of action of phenytoin sodium. Sodium channels are: 1) Closed 2) Open 3) Inactive (phenytoin effect) Phenytoin is believed to protect against seizures by causing voltage-dependent block of voltage gated sodium channels. [43] This blocks sustained high frequency repetitive firing of action potentials. This is accomplished by ...

[12] This is probably a side effect or even the actual mechanism of action for some antiepileptic drugs, since GABA can itself, directly or indirectly ...
