Abstract

The invention provides an ornidazole injection which comprises ornidazole, propylene glycol and water for injection, wherein the ornidazole can be well dissolved when the volume of the propylene glycol is 60%-70% of that of the injection. According to a preparation technology for the ornidazole injection, oxygen in the solution can be completely removed by utilizing carbon dioxide gas, and the saturated carbon dioxide gas in the injection can be used for not only reducing the oxidized by-product of the ornidazole injection, but also improving the heat stability of the ornidazole injection.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to an ornidazole injection and a preparation process. Background technique [0002] Ornidazole (ONZ), chemical name: 1-(3-chloro-2-hydroxypropyl)-2-methyl-5-nitroimidazole. Ornidazole is a third-generation nitroimidazole antibiotic, which is used for anaerobic infection, as well as protozoan and trichomonad infection. For the treatment of bacterial infections caused by Bacteroides fragilis, Bacteroides diteri, Bacteroides ovale, Bacteroides polymorpha, Bacteroides vulgaris, Clostridium, Eubacterium, Peptococcus and Peptostreptococcus, Helicobacter pylori, Bacteroides melanin, A variety of infectious diseases caused by sensitive anaerobic bacteria such as Fusobacterium, CO2 Phagocytosis, and Bacteroides gingivalis; treatment of severe amoebic diseases in the digestive system, such as amoebic dysentery, amoebic liver abscess, etc. [0003] Ornidazole injection is the main ...
