OXALIPLATIN vs VALCHLOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxaliplatin is a platinum-based alkylating agent that forms inter- and intrastrand DNA crosslinks, inhibiting DNA replication and transcription, leading to cell death.
Valchlor (mechlorethamine) is a nitrogen mustard alkylating agent that forms cross-links between DNA strands, leading to inhibition of DNA replication and transcription, and inducing apoptosis in rapidly dividing cells.
85 mg/m² intravenously over 2 hours every 2 weeks in combination with 5-fluorouracil and leucovorin (FOLFOX regimen).
Topical: Apply 0.016% mechlorethamine gel to affected areas once daily.

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.
Clinical Note
moderateOxaliplatin + Digoxin
"Oxaliplatin may decrease the cardiotoxic activities of Digoxin."
Clinical Note
moderateOxaliplatin + Digitoxin
"Oxaliplatin may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateOxaliplatin + Deslanoside
"Oxaliplatin may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateOxaliplatin + Acetyldigitoxin
"Oxaliplatin may decrease the cardiotoxic activities of Acetyldigitoxin."
The terminal elimination half-life is approximately 24 hours after topical application, supporting daily dosing. Systemic half-life may be prolonged in patients with hepatic impairment.
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.
Following topical application, VALCHLOR (mechlorethamine) is systemically absorbed; approximately <10% is excreted unchanged in urine. The majority of the dose is eliminated via metabolism and biliary/fecal routes, with ~50% of a systemic dose recovered in feces as metabolites.
