Problems solved by technology

[0006] However, the samples prepared by the above process still have the following problems: ①The temperature in the pre-freezing stage is relatively single, which may easily lead to uneven dispersion of the drug in the freeze-dried sample; ②Bortezomib is easily oxidized, and nitrogen filling can protect bortezomib from oxidation reactions However, the oxygen content limit is not indicated; ③ Bortezomib has poor thermal stability, if its suspension is heated, it will easily cause an increase in impurity content, thereby affecting product quality

Abstract

The invention relates to a preparation process of freeze-dried powder injection containing bortezomib. The freeze-dried powder injection contains bortezomib and mannite. By controlling the oxygen content in a solution during preparation and a freeze-drying process, the stability of the bortezomib freeze-dried powder injection is greatly increased, and the re-dissolution time of the freeze-dried powder injection is shortened. The process provided by the invention is simple and easy, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a preparation process of a freeze-dried powder injection containing an active ingredient of bortezomib. Background technique [0002] Bortezomib, chemical name [(1R)-3-methyl-1-[[(2S)-1-oxo-3-phenyl-2-[(pyrazinecarboxy)amino]propyl] Amino]butyl]boronic acid, whose trade name is Velcade, was developed by Millennium Pharmaceuticals in the United States. Bortezomib is a reversible inhibitor of the chymotrypsin-like activity of 26S proteasome in mammalian cells, and it is cytotoxic to various types of cancer cells. In general, it should be reconstituted with 0.9% sodium chloride injection, administered by intravenous or subcutaneous injection, and it is mainly used for the treatment of multiple myeloma. [0003] Patent CN105056205A relates to a pharmaceutical composition containing bortezomib and a preparation method thereof. The composition contains bortezomib, mannitol and tert-b...
