Head-to-head clinical analysis: MELPHALAN versus MUSTARGEN.
MELPHALAN vs MUSTARGEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Melphalan is an alkylating agent that forms interstrand crosslinks with DNA, inhibiting DNA replication and transcription, leading to cell death.
MUSTARGEN (mechlorethamine HCl) is a nitrogen mustard alkylating agent that forms cross-links between DNA strands, inhibiting DNA replication and transcription, leading to cell death.
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.
IV: 0.4 mg/kg or 12 mg/m² BSA as a single dose or divided into 0.1 mg/kg/day for 4 days.

Terminal half-life: 1.5-2 hours (IV); prolonged in renal impairment (up to 3-4 hours).
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: 30-60 minutes (rapidly inactivated); clinical context: very short due to rapid hydrolysis and alkylation, necessitating rapid administration after reconstitution.
Renal: 10-15% unchanged; hepatic metabolism (20-30%) with biliary excretion of metabolites; fecal: <5%.
Renal: 50% as unchanged drug and metabolites; fecal: minor (<10%); biliary: minimal.
