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 agent that intercalates with DNA and inhibits topoisomerase II, leading to inhibition of DNA replication and transcription, and ultimately cell death. It also generates free radicals and induces apoptosis.
Doxorubicin HCl liposome injection 20 mg/m2 intravenously over 1 hour every 4 weeks.
12 mg/m² IV daily for 3 days (acute myeloid leukemia) or 12 mg/m² IV daily for 3 days (acute lymphoblastic leukemia); maximum cumulative dose 600 mg/m².

Terminal half-life is approximately 30–40 hours, prolonging drug exposure and allowing every-4-week dosing.
Terminal elimination half-life: 20-30 hours (mean ~22 hours). Prolonged in severe hepatic impairment (up to 40 hours) and may be extended in patients with renal impairment due to accumulation of active metabolite idarubicinol (half-life > 60 hours).
Primarily hepatic metabolism and biliary excretion; urinary excretion accounts for <10% of the administered dose as unchanged drug.
Primarily hepatic metabolism; biliary excretion of metabolites accounts for ~50% of total elimination. Renal excretion of unchanged drug is minimal (<10%). Approximately 30-40% of the dose is recovered in urine as metabolites. Fecal elimination of metabolites accounts for ~50%.
