Abstract

The invention discloses a compound docetaxel ester microsphere injection and a preparation method thereof, belonging to the technical field of medicines. The compound docetaxel ester microsphere injection is characterized by being prepared from the following raw materials in weight parts: 0.5 to 5 parts of docetaxel, 30-150 parts of Brucea javanica oil, 30-150 parts of middle-chain triglyceride, 10-30 parts of lecithin, 10-60 parts of polyethylene glycol surface active agents, 20-35 parts of glycerine and 700-950 parts of sterilized water for injection. The compound docetaxel ester microsphere injection of the invention is oil in water type microsphere preparation. The docetaxel as a main drug is coated in the Brucea javanica and middle-chain triglyceride compound oil phase of the oil in water type microsphere. The microsphere has a smaller grain diameter (which is lower than 100nm), and the preparation has better stability. The compound oil phase compositions play a cooperative anticancer role, and reduce the stimulation reaction of the injection and the side reactions such as hemolysis, allergy and the like. The invention has targeting function and increases the medicine effect.

Description

technical field [0001] The invention relates to a compound docetaxel lipid microsphere injection and a preparation method. The preparation has good anticancer effect and belongs to the technical field of medicines. Background technique [0002] Docetaxel is a derivative of paclitaxel, also known as docetaxel, the English name is Docetaxel, and the chemical name is {2aR-[2aα, 4β, 4aβ, 6β, 9α(αR * , βs * ), 11α, 12α, 12aα, 12bα]}-β-{[(1,1-dimethylethoxy)carbonyl]amino}-α-carbonylphenylpropanoic acid [12b-acetoxy-12-benzoyl Oxy-2a, 3, 4, 4a, 5, 6, 9, 10, 11, 12, 12a, 12b-dodecahydro-4, 6, 11-trihydroxy-4a, 8, 13, 13-tetramethyl -5-Oxo-7,11-methylene-1H-cyclodecapenta[3,4]benzo[1,2-b]oxetan-9-yl]ester. Paclitaxel has a unique anti-cancer mechanism. It prevents the growth of tumor cells by inducing and promoting tubulin polymerization, assembly and stabilizing microtubules. Significant curative effect in prostate cancer. Since it was launched in the United States in 1993, it...
