Abstract

A taxi-alcohol injection is prepared from taxi-alcohol, solvent for injection and stabilizer through dissolving the stabilizer in said solvent by thermal stirring or ultrasonic stirring, adding taxi-alcohol, stirring, filtering, loading it in containers and sterilizing. It has low toxic by-effect.

Description

Technical field [0001] The invention relates to the technical field of medicine, in particular to a new formulation and preparation method of a new type of paclitaxel injection prepared by dissolving the anticancer drug paclitaxel with an injection solvent and using an appropriate stabilizer. Background technique [0002] Paclitaxel (Paclitaxel, trade name Taxol) is a highly effective anticancer drug extracted from Taxus brevidolia (Pacific yew), a plant belonging to the Taxus family. It is a complex diterpenoid compound with a molecular formula of C 47 H 51 NO 14 , The relative molecular mass is 853.9. Paclitaxel has good anti-cancer activity and is used for the treatment of ovarian cancer, breast cancer, colon cancer, non-small cell lung cancer, neck cancer, melanoma, etc., with good curative effect. [0003] The solubility of paclitaxel in water is very small, almost insoluble in water (<0.004mg / ml), the bioavailability of oral administration is poor, and it can only be adm...
