A liposome-encapsulated form of the citrate salt of the anthracycline antineoplastic antibiotic daunorubicin. Daunorubicin intercalates into DNA and interacts with topoisomerase II, thereby inhibiting DNA replication and repair and RNA and protein synthesis. Liposomal delivery of doxorubicin citrate improves drug penetration into tumors and decreases drug clearance, thereby increasing the duration of therapeutic drug effects.
