KONVOMEP vs VALPROATE SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Increases GABA levels by inhibiting GABA transaminase and blocking voltage-gated sodium channels; also modulates T-type calcium channels.
IV: 8 mg (as netupitant 235 mg/palonosetron 0.25 mg combination) over 15 minutes on day 1 of chemotherapy.
10-15 mg/kg/day orally or intravenously in 2-3 divided doses; increase by 5-10 mg/kg/day weekly to therapeutic range of 50-100 mcg/mL. Maximum dose 60 mg/kg/day.

Terminal elimination half-life: 8-12 hours in healthy adults. Extended to 18-24 hours in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 9–16 hours in adults; may be shorter in children (5–12 hours) and prolonged in hepatic impairment or elderly (up to 18 hours). Neonatal half-life: 10–67 hours. Clinically, twice-daily dosing is typical.
Renal: approximately 70% as unchanged drug; fecal: approximately 20% as metabolites; biliary: negligible.
Primarily renal (90% as glucuronide conjugates, 3-oxo derivative, and other metabolites; <3% unchanged). Biliary/fecal excretion accounts for <10%.
