Abstract

The invention provides an azlocillin sodium freeze-dried powder injection for injection prepared from double excipients, relates to the field of pharmaceutical preparation and preparation method, andmainly overcomes the defects that the excipients in a production formula of an azlocillin sodium freeze-dried powder injection for injection has long freeze-drying time, high drying temperature and high energy consumption in production in the prior art. The azlocillin sodium freeze-dried powder injection for injection uses double excipients including mannitol and hydroxyethyl starch 130 / 0.4, the main drug is azlocillin sodium, the weight ratio of the main drug to the excipients is (100:100)-(100:130), and the weight ratio of mannitol to hydroxyethyl starch 130 / 0.4 is (100:50)-(100:80). The azlocillin sodium freeze-dried powder injection for injection is prepared from the main drug and the excipients. The azlocillin sodium freeze-dried powder injection for injection provided by the invention has the advantages of stable quality, safety and effectiveness, simple product production process, short drying time, low drying temperature and low energy consumption in production.

Description

Technical field: [0001] The invention relates to the field of pharmaceutical preparations and preparation methods, in particular to an azlocillin sodium freeze-dried powder for injection with double auxiliary materials and a preparation method thereof. Background technique: [0002] Azlocillin sodium for injection is a penicillin antibiotic, the third-generation broad-spectrum semi-synthetic penicillin, mainly used for various infections caused by sensitive Gram-positive bacteria and negative bacteria and Pseudomonas aeruginosa infection, including sepsis, meninges Inflammation, endocarditis, suppurative pleurisy, peritonitis and infection of lower respiratory tract, gastrointestinal tract, biliary tract, urinary tract, bone, soft tissue and reproductive organs, gynecological and obstetrical infection, malignant otitis externa, burns, skin and surgical infection, etc. . At present, the auxiliary materials used in the industrial production of azlocillin sodium freeze-dried p...
