Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Phenytoin stabilizes neuronal membranes by promoting voltage-gated sodium channel inactivation, reducing high-frequency neuronal firing and seizure propagation.
Stabilizes neuronal membranes by blocking voltage-gated sodium channels and inhibiting the release of excitatory neurotransmitters, particularly glutamate and aspartate.
300-400 mg per day orally in divided doses (e.g., 100 mg three times daily); loading dose 1 g orally divided into three doses given at 2-hour intervals, then 100 mg every 6-8 hours for first 24 hours.
Initial: 25 mg orally once daily for 2 weeks, then 50 mg once daily for 2 weeks, then increase by 50 mg every 1-2 weeks. Maintenance: 100-200 mg twice daily (200-400 mg/day). Maximum: 400 mg/day.

Terminal half-life: 7-42 hours (mean 22 hours) in adults; dose-dependent due to saturable metabolism. Steady-state reached in 7-10 days.
