DEPACON vs FYCOMPA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABA concentration in the brain by inhibiting GABA transaminase and blocking voltage-gated sodium channels.
Non-competitive AMPA receptor antagonist; inhibits glutamate-mediated excitatory neurotransmission by selectively targeting AMPA receptors.
10-15 mg/kg/day IV or orally divided every 8 hours; 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.

10–16 hours; neonates 20–30 hours; patients with liver disease up to 18 hours; decreased half-life in patients on enzyme-inducing antiepileptics (e.g., phenytoin, carbamazepine) to 4–9 hours.
Terminal elimination half-life is approximately 105 hours (range 80-120 hours) in patients with epilepsy; supports once-daily dosing.
Primarily renal: >90% of a dose is excreted in urine as valproic acid glucuronide (30–50%), 3-oxo-valproic acid (30–40%), and other metabolites. Less than 3% excreted unchanged. Minor fecal elimination (≈5%).
Renal: approximately 30% as unchanged drug; fecal: approximately 70% (mostly as metabolites, minimal unchanged).
