A. Phenytoin decreases the inhibitory effects of the inhibitory neurotransmitter gammaaminobutyric acid (GABA), which suppresses the excitability of epileptogenic neurons. B. Phenytoin decreases the inactivation of Na+ ion channels to decrease high-frequency firing of neurons and inhibition of Ca ++ ion channels. C.
