  • Liposomal formulations of anthracycline agents and cytidine analogs
    Patent number: 8431806
    Abstract: Compositions which comprise an anthracycline agent, and a cytidine analog are encapsulated in liposomal carriers. The preferred anthracycline agent is selected from the group of daunorubicin, doxorubicin, and idarubicin, while the preferred cytidine analog is selected from the group of cytarabine, gemcitabine, or 5-azacytidine.
