Abstract

The invention relates to the technical field of medicine, in particular to a novel preparation method of docetaxel injection. The prescription of the docetaxel injection of the invention consists of docetaxel, stabilizing agent and menstruum used for injection. The preparation method includes the following steps: (1) the stabilizing agent of a prescription amount is dissolved in the menstruum of the prescription amount used for injection; (2) the docetaxel of the prescription amount is dissolved in the solution obtained in the step (1); and then filtering, sub-package and sterilization are carried out to finish the preparation. The docetaxel injection of the invention has better stability and convenient use.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a novel preparation method of docetaxel injection. Background technique [0002] Docetaxel (docetaxel, trade name Taxotere) is a semi-synthetic paclitaxel derivative with molecular formula C 13 h 53 NO.3H 2 o, molecular weight 861.9. The product was first launched in Mexico in April 1995, and is now available in Britain, the United States, France, Italy, Germany, Japan and other countries. Docetaxel can accelerate the polymerization of tubulin into microtubules and delay the depolymerization of microtubules, resulting in the formation of stable non-functional microtubule bundles, thereby disrupting mitosis and cell proliferation. Its cytotoxic effect is 1.3-12 times that of paclitaxel; the intracellular drug concentration is 3 times that of paclitaxel; the intracellular retention time is 3 times that of paclitaxel. [0003] Docetaxel has anticancer activity against a variet...
