Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vinca alkaloid that binds to tubulin, inhibiting microtubule assembly and mitotic spindle formation, causing metaphase arrest in dividing cells.
Mitoxantrone is a synthetic anthracenedione derivative that intercalates with DNA and inhibits topoisomerase II, leading to DNA strand breaks and inhibition of DNA and RNA synthesis. It also disrupts DNA repair and replication, and has immunosuppressive effects through inhibition of B cell, T cell, and macrophage function.
2.25 mg/m2 intravenously over 1 hour every 7 days. Maximum dose per administration is 3.6 mg.
12 mg/m2 IV over 5-15 minutes once daily on days 1-3 of a 28-day cycle, or as a single dose of 12-14 mg/m2 IV every 21 days. For acute nonlymphocytic leukemia, 12 mg/m2 IV daily for 3 days with cytarabine.

Terminal elimination half-life ranges from 19 to 40 hours (mean 23 hours) in adults. The prolonged half-life in Marqibo (liposomal vincristine) is due to the sustained release from the liposomal formulation, allowing once-weekly dosing.
Terminal elimination half-life: 23-215 hours (mean ~37 hours). The long half-life reflects extensive tissue distribution and slow elimination, allowing weekly dosing.
Primarily hepatobiliary excretion; approximately 5-16% of the dose is excreted unchanged in the urine over 72 hours. Fecal excretion accounts for about 10% of the administered dose, with the remainder undergoing extensive hepatic metabolism and biliary elimination.
Primarily hepatic (biliary/fecal) elimination: ~25% as unchanged drug and metabolites in feces over 5 days; renal excretion accounts for ~11% (6-11%) as unchanged drug. Less than 10% excreted unchanged in urine.
