CARBOPLATIN vs HEXALEN
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.
Alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription, and inducing apoptosis in rapidly dividing cells.
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.
260 mg/m2/day orally in 4 divided doses for 14 or 21 days of a 28-day cycle.

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.
Clinical Note
moderateCarboplatin + Digoxin
"Carboplatin may decrease the cardiotoxic activities of Digoxin."

moderateCarboplatin + Digitoxin
"Carboplatin may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateCarboplatin + Deslanoside
"Carboplatin may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateCarboplatin + Acetyldigitoxin
"Carboplatin may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal elimination half-life is 12-13 hours; prolonged to 24 hours 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%).
Primarily renal and hepatic metabolism; 60-70% excreted in urine as unchanged drug and metabolites; 15-20% eliminated in feces via biliary secretion.
