GLEOSTINE vs MELPHALAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GLEOSTINE (lomustine) is a nitrosourea alkylating agent that crosslinks DNA and RNA, inhibiting DNA synthesis and repair. It is cell cycle phase-nonspecific.
Melphalan is an alkylating agent that forms interstrand crosslinks with DNA, inhibiting DNA replication and transcription, leading to cell death.
130 mg/m2 orally every 6 weeks as a single dose; alternatively, 75 mg/m2 orally every 3 weeks.
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.
