Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABA levels by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase; also blocks voltage-gated sodium channels and T-type calcium channels.
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 dose 750 mg/day PO in divided doses; increase by 250-500 mg/day every 3-7 days; maintenance dose 1000-2000 mg/day PO divided BID or TID; maximum 60 mg/kg/day.
IV: 8 mg (as netupitant 235 mg/palonosetron 0.25 mg combination) over 15 minutes on day 1 of chemotherapy.

Terminal: 9-16 hours (mean 12 h); extended with hepatic dysfunction, co-administered enzyme inhibitors, or in elderly.
Terminal elimination half-life: 8-12 hours in healthy adults. Extended to 18-24 hours in renal impairment (CrCl <30 mL/min).
Renal: <3% as unchanged drug; >95% as metabolites (glucuronide conjugates, oxidation products). Biliary/fecal: minor, <5%.
Renal: approximately 70% as unchanged drug; fecal: approximately 20% as metabolites; biliary: negligible.
