BRIVIACT vs LACOSAMIDE
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.
Selectively enhances slow inactivation of voltage-gated sodium channels, stabilizing hyperexcitable neuronal membranes and inhibiting repetitive neuronal firing.
50 mg orally twice daily; may increase up to 100 mg twice daily based on response and tolerability.
Oral or IV: 50 mg twice daily initially; increase by 50 mg twice daily weekly to maintenance 100-200 mg twice daily. Maximum 200 mg twice daily.

Clinical Note
moderateLacosamide + Sulfisoxazole
"The serum concentration of Sulfisoxazole can be increased when it is combined with Lacosamide."
Clinical Note
moderateLacosamide + Fluconazole
"The serum concentration of Fluconazole can be increased when it is combined with Lacosamide."
Clinical Note
moderateLacosamide + Ketoconazole
"The serum concentration of Ketoconazole can be increased when it is combined with Lacosamide."
Clinical Note
moderateLacosamide + Delavirdine
Terminal 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 elimination half-life is approximately 13 hours (range 12–16 hours) in adults. Steady state achieved after 3 days with BID 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: approximately 95% (40% unchanged, remainder as O-desmethyl metabolite). Fecal: <5%.
