FINTEPLA vs KEPPRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fenfluramine (FINTEPLA) is a serotonin-releasing agent and serotonin receptor agonist, primarily at 5-HT2 receptors. It also acts as a sigma-1 receptor agonist and modulates GABAergic and glutamatergic transmission.
Levetiracetam binds to synaptic vesicle protein 2A (SV2A), modulating neurotransmitter release and reducing neuronal hyperexcitability. It also inhibits high-voltage N-type calcium channels and reduces GABAergic and glycinergic inhibition.
0.1-0.2 mg/kg twice daily (oral), with a maximum of 16 mg/day for patients weighing ≥50 kg; for patients <50 kg, maximum 8 mg/day.
500 mg orally twice daily, titrated up to 1500 mg twice daily as tolerated.

Terminal elimination half-life approximately 9 hours in adults; at steady state, accumulation minimal with twice-daily dosing.
6-8 hours in adults; prolonged to 10-18 hours in renal impairment (CrCl <30 mL/min); clinical context: dosing interval adjustment required in renal disease.
Renal: 65% as unchanged drug; Fecal: 29% primarily as metabolites; Biliary: negligible.
Renal: 66% unchanged; 27% as inactive metabolite; 0.3% fecal.
