DIVALPROEX SODIUM vs ESLICARBAZEPINE ACETATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases brain concentrations of gamma-aminobutyric acid (GABA), blocks voltage-gated sodium channels, and modulates T-type calcium channels.
Eslicarbazepine acetate is a voltage-gated sodium channel blocker that stabilizes the inactive state of sodium channels, reducing high-frequency repetitive firing of neurons. It also modulates T-type calcium channels and enhances slow inactivation of sodium channels.
10-15 mg/kg/day orally in divided doses; increase by 5-10 mg/kg/week; maximum 60 mg/kg/day. Extended-release: 25 mg/kg/day orally; increase by 15 mg/kg/day at weekly intervals; maximum 60 mg/kg/day.
400 mg orally once daily, titrated to a maintenance dose of 800-1200 mg once daily.

Clinical Note
moderateEslicarbazepine acetate + Estrone sulfate
"The serum concentration of Estrone sulfate can be decreased when it is combined with Eslicarbazepine acetate."
Clinical Note
moderateEslicarbazepine acetate + Aripiprazole
"The serum concentration of Aripiprazole can be decreased when it is combined with Eslicarbazepine acetate."
Clinical Note
moderateCyclophosphamide + Eslicarbazepine acetate
"The metabolism of Eslicarbazepine acetate can be decreased when combined with Cyclophosphamide."
Clinical Note
moderate9-16 hours (terminal); shorter in children (6-9 hours) and longer in hepatic disease or elderly; clinical context: twice-daily dosing provides stable trough concentrations.
Terminal half-life of eslicarbazepine is 13-20 hours (mean ~14 hours), supporting once-daily dosing.
Renal: <3% unchanged; primarily hepatic metabolism (glucuronidation, beta-oxidation, cytochrome P450), metabolites eliminated renally; fecal: negligible.
Renal: ~90% (as glucuronide conjugates and unchanged drug; ~30% as eslicarbazepine acetate, ~60% as eslicarbazepine). Fecal: <1%. Biliary: negligible.
