CISPLATIN vs HEPZATO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Platinum-based alkylating-like agent that forms intrastrand and interstrand DNA crosslinks, inhibiting DNA replication and transcription, leading to cell cycle arrest and apoptosis.
HEPZATO (melphalan) is a nitrogen mustard alkylating agent that crosslinks DNA strands, inhibiting DNA replication and transcription, leading to cell death.
50-100 mg/m² IV every 3-4 weeks; or 20 mg/m² IV daily for 5 days every 3-4 weeks.
Melphalan 3 mg/kg ideal body weight via hepatic artery infusion over 15-30 minutes followed by hemofiltration, administered once per treatment cycle.

The terminal elimination half-life is 20-30 hours (range 10-40 hours) in patients with normal renal function. This prolonged half-life is due to slow release of platinum from tissue binding and is clinically relevant for cumulative nephrotoxicity and ototoxicity.

"Cisplatin may decrease the cardiotoxic activities of Acetyldigitoxin."
The terminal elimination half-life of melphalan is approximately 1.5 hours following intravenous administration. This short half-life necessitates regional delivery (hepatic arterial infusion) to achieve high local concentrations with limited systemic exposure.
Renal excretion accounts for 70-90% of cisplatin elimination, with approximately 20-50% excreted unchanged in the urine within 24 hours. Biliary/fecal excretion is minimal (<5%).
HEPZATO (melphalan hydrochloride) for injection is renally eliminated; approximately 20-30% of the administered dose is excreted unchanged in the urine over 24 hours. The major metabolites are hydrolysis products, which are also excreted renally. Biliary/fecal elimination accounts for less than 10% of the dose.
