CARBOPLATIN vs IFEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Carboplatin forms platinum-DNA adducts, causing intrastrand crosslinks and G2/M cell cycle arrest, leading to apoptosis.
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).
IV infusion over 15-60 minutes, target AUC 4-6 using Calvert formula (dose = target AUC × (GFR + 25)). Adults: typical initial dose 400 mg/m² every 4 weeks or AUC 5-6 every 3-4 weeks.
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.

Terminal elimination half-life: 2.6-5.9 hours in adults with normal renal function. In patients with creatinine clearance <60 mL/min, half-life is prolonged (up to 17-26 hours). Clinically, dosing adjustments are required based on Calvert formula using glomerular filtration rate.
Terminal elimination half-life is approximately 15 hours in adults with normal renal function; prolonged in renal impairment.
Renal: ~65% of platinum excreted in urine within 24 hours, primarily as unchanged carboplatin; ~32% as metabolites. Biliary/fecal excretion is minimal (<6%).
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%.
