Abstract

A lipid injection of Zhengdingmycin or zhengdingmycin hydrochloride is prepared from Zhengdingmycin or zhengdingmycin hydrochloride, neutral phosphide, negative-charge phosphide, cholesterol, antioxidizing agent, organic acid, alkali, sugar, buffer and the water for injection through preparing liposome, homogenizing coating, purifying, solidifying, and sterilizing. Its advantages are high stability and low toxic by-effect.

Description

technical field [0001] The invention relates to a preparation of daunorubicin or daunorubicin hydrochloride, in particular to a daunorubicin or daunorubicin hydrochloride liposome injection, and also relates to a preparation process of the medicine. Background technique [0002] Daunorubicin or daunorubicin hydrochloride is an anthracycline broad-spectrum antitumor antibiotic. Its mechanism of action is mainly through its insertion into the DNA double helix and binding to DNA to change its template. This chimerism can lead to DNA space Structural barriers, thereby inhibiting DNA and RNA polymerases, preventing DNA and RNA synthesis. Daunorubicin hydrochloride has a broad-spectrum anti-experimental tumor effect, and is mainly used for acute lymphocytic or myeloid leukemia that is resistant to commonly used anti-tumor drugs. It also has a certain effect on lymphosarcoma, neuroblastoma, osteosarcoma, skeletal muscle tumor and choriocarcinoma. Although daunorubicin hydrochlori...
