ESLICARBAZEPINE ACETATE vs VIMPAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Selective enhancement of slow inactivation of voltage-gated sodium channels, resulting in stabilization of hyperexcitable neuronal membranes and inhibition of repetitive neuronal firing.
400 mg orally once daily, titrated to a maintenance dose of 800-1200 mg once daily.
Adults: 200 mg oral or IV as a loading dose, followed by 100 mg twice daily (200 mg/day) starting the day after loading. May increase by 50 mg twice daily every week up to 200 mg twice daily (400 mg/day).

Clinical Note
moderateEslicarbazepine acetate + Estrone sulfate

"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
moderateTerminal half-life of eslicarbazepine is 13-20 hours (mean ~14 hours), supporting once-daily dosing.
Terminal half-life: 13-16 hours (mean ~13 h at steady state); prolonged with renal impairment (CrCl <30 mL/min: ~22 h) and in patients with hepatic impairment (Child-Pugh B: ~17 h; Child-Pugh C: ~22 h).
Renal: ~90% (as glucuronide conjugates and unchanged drug; ~30% as eslicarbazepine acetate, ~60% as eslicarbazepine). Fecal: <1%. Biliary: negligible.
Renal: ~95% (40% as parent drug, 39% as O-desmethyl metabolite, and ~15% as other minor metabolites); minimal biliary/fecal elimination (less than 1%).
