Abstract

A method for enhancing the therapeutic effectiveness of adriamycin, in the treatment of cancer, is disclosed. Liposomes containing coentrapped adriamycin and a secondary compound effective to reduce the toxicity of adriamycin or enhance the induction by adriamycin of the tumoricidal activity of host lymphoid cells, such as lipopolysaccharide, are administered parenterally in a therapeutically effective dose. In another aspect, macrophages stimulated in vivo with liposomes containing entrapped liposomes are exposed to an immunostimulator, for enhanced tumoricidal activity. Also disclosed are liposome compositions containing coentrapped adriamycin and an immunostimulator.
