BUSULFEX vs OXALIPLATIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Busulfan is a bifunctional alkylating agent that cross-links DNA, leading to inhibition of DNA replication and cell death.
Oxaliplatin is a platinum-based alkylating agent that forms inter- and intrastrand DNA crosslinks, inhibiting DNA replication and transcription, leading to cell death.
Busulfan 0.8 mg/kg IV every 6 hours for 4 days (total 16 doses) or 3.2 mg/kg IV once daily for 4 days, based on ideal body weight or actual body weight (whichever is lower).
85 mg/m² intravenously over 2 hours every 2 weeks in combination with 5-fluorouracil and leucovorin (FOLFOX regimen).

Terminal elimination half-life is approximately 2.5 hours (range: 1.5-4.0 hours) in adults. In children, half-life is shorter (~1.4 hours). Clinically, this supports high-dose, fractionated dosing regimens (e.g., every 6 hours) to maintain therapeutic levels.

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.
Primarily hepatic metabolism via conjugation with glutathione, followed by renal excretion of metabolites. Less than 2% of the parent drug is excreted unchanged in urine. Fecal excretion is negligible.
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.
