Abstract

The present invention discloses a gemcitabine hydrochloride lyophilized preparation. The lyophilized preparation comprises, by weight, 20-70 parts of gemcitabine hydrochloride, 15-60 parts of a lyoprotectant and 0.005-0.5 parts of an antioxidant. Compared to the prior art, with the gemcitabine hydrochloride lyophilized preparation provided by the present invention, the problem of the stability ofthe gemcitabine hydrochloride is solved; the product quality is ensured; the risk of drug using is reduced; the preparation process is simple, the cost is low; and the preparation is suitable for theindustrial production, and has practical value.

Description

technical field [0001] The invention relates to a gemcitabine hydrochloride freeze-dried preparation, which belongs to the technical field of pharmaceutical preparations. Background technique [0002] Gemcitabine hydrochloride is a new type of artificially synthesized difluoronucleoside antimetabolite and antitumor drug. Its chemical name is 2-deoxy-2,2-difluorodeoxycytidine hydrochloride (β-isomer), developed by Eli Lilly and Company It was developed and approved for marketing in South Africa, Sweden, the Netherlands, Australia and other countries in 1995. It was also approved by the US FDA in 1996. It is clinically used for the first-line treatment of non-small cell lung cancer and pancreatic cancer. [0003] This product is a cell cycle-specific anti-metabolism drug, which mainly acts on tumor cells in the DNA synthesis phase, that is, cells in the S phase. Under certain conditions, it can prevent the progress from the G1 phase to the S phase; Rat tumors have obvious cyt...
