NCI Drug Dictionary


liposomal mitoxantrone hydrochloride 
A formulation composed of the hydrochloride salt form of the anthracenedione antibiotic mitoxantrone encapsulated within liposomes, with potential antineoplastic activity. Upon intravenous administration, mitoxantrone intercalates into and forms crosslinks with DNA, thereby disrupting DNA and RNA replication. This agent also binds to topoisomerase II, which both results in DNA strand breaks and prevents DNA synthesis. This leads to the induction of apoptosis in the rapidly dividing cancer cells. The liposomal delivery of mitoxantrone improves drug penetration into tumors and decreases drug clearance, thereby increasing drug circulation and therapeutic efficacy while lowering the toxic effects. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
