Select the Statement That Is Consistent with the Mechanism of Action

Select the statement that is consistent with the mechanism of action of phenytoin (Dilantin) that helps decrease the occurrence of a seizure.

A) Phenytoin prolongs the inactivation period of sodium (Na⁺) channels in the nerve membrane, leading to a reduction in the generation of high-frequency repetitive firing of action potentials from neurons involved in initiating seizures.
B) Phenytoin shortens the inactivation period of sodium (Na⁺) channels in the nerve membrane, leading to a reduction in the generation of high-frequency repetitive firing of action potentials from neurons involved in initiating seizures.
C) Phenytoin prolongs the inactivation period of potassium (K⁺) channels in the nerve membrane, leading to a reduction in the generation of high-frequency repetitive firing of action potentials from neurons involved in initiating seizures.
D) None of these are correct.
