BRIVIACT vs ESLICARBAZEPINE ACETATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Brivaracetam is a synaptic vesicle glycoprotein 2A (SV2A) ligand with high affinity. The exact mechanism by which it exerts its antiepileptic effect is unknown, but binding to SV2A is thought to modulate neurotransmitter release.
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.
50 mg orally twice daily; may increase up to 100 mg twice daily based on response and tolerability.
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
moderateTerminal elimination half-life is approximately 9 hours (range 7–11 hours). This supports a twice-daily dosing regimen (e.g., 50 mg twice daily) with steady state achieved within approximately 2 days.
Terminal half-life of eslicarbazepine is 13-20 hours (mean ~14 hours), supporting once-daily dosing.
Approximately 95% of the dose is excreted in urine as metabolites or unchanged drug (<1% unchanged). About 0.8% is excreted in feces via biliary elimination.
Renal: ~90% (as glucuronide conjugates and unchanged drug; ~30% as eslicarbazepine acetate, ~60% as eslicarbazepine). Fecal: <1%. Biliary: negligible.
