DEPAKOTE vs FYCOMPA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABA levels by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase; 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.
Initial dose 750 mg/day PO in divided doses; increase by 250-500 mg/day every 3-7 days; maintenance dose 1000-2000 mg/day PO divided BID or TID; maximum 60 mg/kg/day.
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: 9-16 hours (mean 12 h); extended with hepatic dysfunction, co-administered enzyme inhibitors, or in elderly.
Terminal elimination half-life is approximately 105 hours (range 80-120 hours) in patients with epilepsy; supports once-daily dosing.
Renal: <3% as unchanged drug; >95% as metabolites (glucuronide conjugates, oxidation products). Biliary/fecal: minor, <5%.
Renal: approximately 30% as unchanged drug; fecal: approximately 70% (mostly as metabolites, minimal unchanged).
