Problems solved by technology

[0004] Ceftizoxime Sodium Injection, which is already on the market, is a powder injection, but it still needs to be stored at low temperature to avoid discoloration of the drug during use
In addition, during the production process, activated carbon is added for decolorization and then filtered, which may easily lead to insufficient content. The pH value of the product is prone to fluctuations during storage, which is unstable. At the same time, the dissolution rate is not ideal, and the validity period is only 12 months.

Abstract

The invention relates to a novel pharmaceutical preparation composition, in particular to a ceftizoxime sodium-containing preparation for injection and a preparation method for the ceftizoxime sodium-containing preparation. The ceftizoxime sodium-containing preparation for injection comprises the following components: ceftizoxime sodium, mannitol, EDTA (Ethylene Diamine Tetraacetic Acid) calcium,vitamin C, sodium hydrogen citrate, 2000ml of trisodium citrate buffer solution and water for injection.

Description

Technical field: [0001] The invention relates to a new pharmaceutical preparation composition, in particular to an injection preparation of ceftizoxime sodium, its prescription, application and preparation method. Background technique: [0002] Ceftizoxime sodium, a semi-synthetic third-generation cephalosporin, has a broad antibacterial spectrum. Similar to cefotaxime, it has a moderate antibacterial effect on Gram-positive bacteria and a strong effect on Gram-negative bacteria. Including: Staphylococcus aureus, Streptococcus, Pneumococcus, Haemophilus influenzae, Streptococcus pneumoniae, Enterobacter, Klebsiella, Proteus and Enterobacteriaceae. Some Gram-negative bacteria resistant to first-generation cephalosporins and gentamicin may be sensitive to this product. But Streptococcus faecalis and methicillin-resistant Staphylococcus are not sensitive to this product. Mainly used for sepsis caused by sensitive bacteria, respiratory system infection, urinary and reproductiv...
