Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Valproate increases GABA concentration in the brain by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase. It also blocks voltage-gated sodium channels and T-type calcium channels.
Non-competitive AMPA receptor antagonist; inhibits glutamate-mediated excitatory neurotransmission by selectively targeting AMPA receptors.
250-500 mg orally twice daily, titrated by 250 mg/day every 3-7 days; maximum 60 mg/kg/day. Target trough serum concentration: 50-100 mcg/mL.
Initial: 2 mg orally once daily; titrate weekly by 2 mg increments to maintenance dose of 4-12 mg once daily depending on seizure type and tolerability; maximum 12 mg once daily.

Terminal elimination half-life is 9-16 hours (mean ~12 hours) in adults; prolonged in hepatic impairment, elderly, and neonates.
Terminal elimination half-life is approximately 105 hours (range 80-120 hours) in patients with epilepsy; supports once-daily dosing.
Renal: 30-50% as glucuronide conjugates, 3% as unchanged drug; fecal: minimal; less than 3% excreted in bile.
Renal: approximately 30% as unchanged drug; fecal: approximately 70% (mostly as metabolites, minimal unchanged).
