EPITOL vs ESLICARBAZEPINE ACETATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Carbamazepine stabilizes the inactivated state of voltage-gated sodium channels, thereby inhibiting high-frequency repetitive firing of action potentials and reducing synaptic transmission.
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.
Carbamazepine, immediate-release: initial 200 mg orally twice daily; increase by 200 mg/day at weekly intervals. Typical maintenance: 800-1200 mg/day in 2-3 divided doses. Extended-release: initial 200 mg orally twice daily; maintenance 400-600 mg twice daily.
400 mg orally once daily, titrated to a maintenance dose of 800-1200 mg once daily.

Clinical Note
moderateCyclophosphamide + Eslicarbazepine acetate
"The metabolism of Eslicarbazepine acetate can be decreased when combined with Cyclophosphamide."
Clinical Note
moderate20-40 hours (mean 30 hours); linear kinetics at therapeutic doses; decreased with concomitant enzyme-inducing drugs
Terminal half-life of eslicarbazepine is 13-20 hours (mean ~14 hours), supporting once-daily dosing.
Renal: 70% (as glucuronide conjugates and other metabolites), Fecal: 30% (unchanged and metabolites)
Renal: ~90% (as glucuronide conjugates and unchanged drug; ~30% as eslicarbazepine acetate, ~60% as eslicarbazepine). Fecal: <1%. Biliary: negligible.
