Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Platinum-based alkylating-like agent that forms intrastrand and interstrand DNA crosslinks, inhibiting DNA replication and transcription, leading to cell cycle arrest and 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).
50-100 mg/m² IV every 3-4 weeks; or 20 mg/m² IV daily for 5 days 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.

The terminal elimination half-life is 20-30 hours (range 10-40 hours) in patients with normal renal function. This prolonged half-life is due to slow release of platinum from tissue binding and is clinically relevant for cumulative nephrotoxicity and ototoxicity.
Clinical Note
moderateCisplatin + Digoxin
"Cisplatin may decrease the cardiotoxic activities of Digoxin."
Clinical Note
moderateCisplatin + Digitoxin
"Cisplatin may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateCisplatin + Deslanoside
"Cisplatin may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateCisplatin + Acetyldigitoxin
"Cisplatin may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal elimination half-life is approximately 15 hours in adults with normal renal function; prolonged in renal impairment.
Renal excretion accounts for 70-90% of cisplatin elimination, with approximately 20-50% excreted unchanged in the urine within 24 hours. Biliary/fecal excretion is minimal (<5%).
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%.
