MUSTARGEN vs VIVIMUSTA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
VIVIMUSTA is a nitrogen mustard alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription, leading to cell death.
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.
100 mg/m2 intravenously over 30 minutes on days 1-3 of a 21-day cycle.

Terminal half-life: 30-60 minutes (rapidly inactivated); clinical context: very short due to rapid hydrolysis and alkylation, necessitating rapid administration after reconstitution.
Terminal elimination half-life is 12 hours (range 10-14 h) in adults with normal renal function; prolonged to 24-36 h in moderate renal impairment (CrCl 30-50 mL/min).
Renal: 50% as unchanged drug and metabolites; fecal: minor (<10%); biliary: minimal.
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other
