Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Doxorubicin intercalates between DNA base pairs, inhibits topoisomerase II, and generates free radicals, leading to DNA damage and cell death. Liposomal encapsulation prolongs circulation time and alters biodistribution.
Idarubicin is an anthracycline antineoplastic antibiotic that intercalates with DNA and inhibits topoisomerase II, resulting in DNA strand breaks and inhibition of nucleic acid synthesis.
Doxorubicin HCl liposome injection 20 mg/m2 intravenously over 1 hour every 4 weeks.
12 mg/m² intravenously over 10 to 15 minutes daily for 3 days (induction) or 12 mg/m² intravenously daily for 2 days (consolidation).

Terminal half-life is approximately 30–40 hours, prolonging drug exposure and allowing every-4-week dosing.
Terminal elimination half-life of idarubicin is 20-30 hours; idarubicinol (active metabolite) has a terminal half-life of 45-60 hours, extending myelosuppression duration.
Primarily hepatic metabolism and biliary excretion; urinary excretion accounts for <10% of the administered dose as unchanged drug.
Renal (approximately 5-12% as unchanged drug and metabolites), biliary/fecal (significant, with 40-50% recovered in feces over 7 days).
