Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABA concentration in the brain by inhibiting GABA transaminase and blocking voltage-gated sodium 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.
10-15 mg/kg/day IV or orally divided every 8 hours; 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.

10–16 hours; neonates 20–30 hours; patients with liver disease up to 18 hours; decreased half-life in patients on enzyme-inducing antiepileptics (e.g., phenytoin, carbamazepine) to 4–9 hours.
Terminal elimination half-life: 8-12 hours in healthy adults. Extended to 18-24 hours in renal impairment (CrCl <30 mL/min).
Primarily renal: >90% of a dose is excreted in urine as valproic acid glucuronide (30–50%), 3-oxo-valproic acid (30–40%), and other metabolites. Less than 3% excreted unchanged. Minor fecal elimination (≈5%).
Renal: approximately 70% as unchanged drug; fecal: approximately 20% as metabolites; biliary: negligible.
