Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-competitive AMPA receptor antagonist; inhibits glutamate-mediated excitatory neurotransmission by selectively targeting AMPA receptors.
Fosnetupitant is a neurokinin-1 (NK1) receptor antagonist that inhibits substance P binding; palonosetron is a serotonin-3 (5-HT3) receptor antagonist that blocks emetic signals in the chemoreceptor trigger zone and gastrointestinal tract.
Initial: 2 mg orally once daily; titrate weekly by 2 mg increments to maintenance dose of 4-12 mg once daily depending on seizure type and tolerability; maximum 12 mg once daily.
IV: 8 mg (as netupitant 235 mg/palonosetron 0.25 mg combination) over 15 minutes on day 1 of chemotherapy.

Terminal elimination half-life is approximately 105 hours (range 80-120 hours) in patients with epilepsy; supports once-daily dosing.
Terminal elimination half-life: 8-12 hours in healthy adults. Extended to 18-24 hours in renal impairment (CrCl <30 mL/min).
Renal: approximately 30% as unchanged drug; fecal: approximately 70% (mostly as metabolites, minimal unchanged).
Renal: approximately 70% as unchanged drug; fecal: approximately 20% as metabolites; biliary: negligible.
