IFEX vs OXALIPLATIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IFEX (ifosfamide) is an alkylating agent that crosslinks DNA strands, inhibiting DNA synthesis and transcription. It requires hepatic activation via CYP3A4 to form active metabolites (ifosfamide mustard and acrolein).
Oxaliplatin is a platinum-based alkylating agent that forms inter- and intrastrand DNA crosslinks, inhibiting DNA replication and transcription, leading to cell death.
1.2 g/m2 intravenously daily for 5 consecutive days every 3 weeks, or 5 g/m2 as a 24-hour continuous infusion every 3 weeks.
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 15 hours in adults with normal renal function; prolonged in renal impairment.
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: approximately 50-70% of the administered dose is excreted in urine as unchanged drug; biliary/fecal excretion is minimal, accounting for less than 5%.
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.
