GLEOSTINE vs OXALIPLATIN
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.
Oxaliplatin is a platinum-based alkylating agent that forms inter- and intrastrand DNA crosslinks, 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.
85 mg/m² intravenously over 2 hours every 2 weeks in combination with 5-fluorouracil and leucovorin (FOLFOX regimen).

"Oxaliplatin may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal elimination half-life is approximately 40-50 hours for ultrafilterable platinum (active species) and 240-500 hours for total platinum (bound to plasma proteins and erythrocytes). The prolonged half-life reflects slow release from tissue binding.
Renal: 60% (as metabolites), Fecal: <5% (unchanged and metabolites), Biliary: minimal
Renal excretion accounts for approximately 50% of the administered platinum, with the remainder eliminated via biliary/fecal routes. Platinum accumulates in erythrocytes and is slowly cleared.
