Embodiment 1
[0044] Put 90mg of PLGA (copolymer of glycolic acid and glycolic acid with a weight ratio of glycolic acid and glycolic acid of 25:75) with a molecular weight of 10000 into a container, add 100ml of dichloromethane, dissolve and mix well, then add 10mg of docetaxel Match, shake again and vacuum dry to remove organic solvents. The dried solid composition is immediately shaped, and then ray sterilized after being dispensed to obtain an anticancer pharmaceutical composition containing 10% by weight of docetaxel. The drug release time of the anticancer drug composition in the in vitro physiological saline is 15-30 days, and the drug release time under the skin of the mouse is 30-45 days.
Embodiment 2
[0045] Example 2. As described in Example 1, the difference is that the active ingredient contained is one of the following:
[0046] 2'-hydroxypaclitaxel, 10-deacetylbaccatin III, 14β-hydroxy-10-deacetylbaccatin III, 9-dihydro-13-baccatin III, 13-(N-tri- Butoxycarbonyl-β-isobutylisoserine)-14-hydroxybaccatin-1,14-carbonate, new paclitaxel, strange new paclitaxel, 3'-(2-methyl-1-propenyl ) Paclitaxel, 3'-(2-methylpropyl)paclitaxel, 4a-paclitaxel, 4b-paclitaxel, 5a-paclitaxel, 10-deacetylpaclitaxel, 7-epi-paclitaxel, baccatin, baccatin III , Baccatin V, spruce yew, Canadian yew, berry yew, Chinese yew, sharp tooth yew, cultivated yew, Yunnan yew or Florida yew, the active ingredients are in the anticancer drug composition The weight percentage is 5-30%.
Embodiment 3
[0048] Put 90 mg of pharmaceutical excipient ethylene vinyl acetate copolymer (EVAc) into a container, add 100 ml of dichloromethane to dissolve and mix, add 10 mg of 7-epi-paclitaxel, shake again, and vacuum dry to remove organic solvents. The dried solid composition is immediately shaped, and then irradiated to sterilize the dried solid composition to obtain an anticancer pharmaceutical composition containing 10% by weight of 7-epi-paclitaxel. The drug release time of the anticancer drug composition in vitro in physiological saline is 14-24 days, and the drug release time under the skin of mice is 20-35 days.
