CARBOPLATIN vs GLEOSTINE
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.
GLEOSTINE (lomustine) is a nitrosourea alkylating agent that crosslinks DNA and RNA, inhibiting DNA synthesis and repair. It is cell cycle phase-nonspecific.
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.
130 mg/m2 orally every 6 weeks as a single dose; alternatively, 75 mg/m2 orally 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.

16-48 hours (terminal), with an active metabolite half-life of up to 5 days, requiring dose adjustment for 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: 60% (as metabolites), Fecal: <5% (unchanged and metabolites), Biliary: minimal
