Liposome preparation

Abstract

The present invention provides a liposome preparation containing oxaliplatin and derivatized with a hydrophilic polymer, as well as a pharmaceutical composition for treatment of tumor comprising the liposome preparation. The liposome preparation according to the present invention is characterized in that it is derivatized with a ligand. The ligand is preferably transferrin. In accordance with the invention, the uptake of a pharmaceutical agent in the liposome into tumor cells can be enhanced through transferrin receptors expressed on the surface of the tumor cells.
