HEPZATO vs MELPHALAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
HEPZATO (melphalan) is a nitrogen mustard alkylating agent that crosslinks DNA strands, inhibiting DNA replication and transcription, leading to cell death.
Melphalan is an alkylating agent that forms interstrand crosslinks with DNA, inhibiting DNA replication and transcription, leading to cell death.
Melphalan 3 mg/kg ideal body weight via hepatic artery infusion over 15-30 minutes followed by hemofiltration, administered once per treatment cycle.
Melphalan 0.25 mg/kg/day orally for 4 consecutive days, repeated every 4-6 weeks; or 16 mg/m² intravenously over 15-20 minutes at 2-week intervals for 4 doses.

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.
Clinical Note
moderateMelphalan + Digoxin
"Melphalan may decrease the cardiotoxic activities of Digoxin."
Clinical Note
moderateMelphalan + Digitoxin
"Melphalan may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateMelphalan + Deslanoside
"Melphalan may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateMelphalan + Acetyldigitoxin
"Melphalan may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal half-life: 1.5-2 hours (IV); prolonged in renal impairment (up to 3-4 hours).
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.
Renal: 10-15% unchanged; hepatic metabolism (20-30%) with biliary excretion of metabolites; fecal: <5%.
