    • The present invention provides a nano-micellar preparation of anthracycline antitumor antibiotics for intravenous injection, which comprises a therapeutically effective amount of anthracycline antitumor antibiotics, a phosphatide derivatized with polyethylene glycol, together with pharmaceutically acceptable adjuvants. The preparation is prepared by encapsulating the medicament with a nano-micelle to obtain the nano-micellar preparation of anthracycline antitumor antibiotics for injection. The anthracycline antitumor antibiotics and the phosphatide derivatized with polyethylene glycol form a nano-micelle with a highly homogeneous particle size. In the micelle, the hydrophobic core of encapsulated medicament is surrounded by polyethylene glycol molecules to form a hydrophilic protective layer, so that the medicament is prevented from contacting with the enzymes and other protein molecules in blood and being recognized and phagocytozed by reticuloendothelial system in the body, and the circulation time in vivo of the micelle is prolonged.
