Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Purine nucleoside analog that inhibits DNA synthesis and repair by incorporating into DNA and inhibiting ribonucleotide reductase and DNA polymerases.
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.
5 mg/m2 intravenously over 20-30 minutes every 3 weeks.
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 is approximately 5-8 hours in patients with normal renal function. Clinically, the half-life may be prolonged in renal impairment, requiring dose adjustments.
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 renal excretion; approximately 50-70% of the dose is excreted unchanged in urine within 24 hours. Minor biliary/fecal elimination accounts for <5%.
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.
