Abstract

The invention discloses a liposome injection prepared from ceftriaxone sodium tazobactam sodium medicinal composition, comprising the following components in parts by weight: 3 parts of ceftriaxone sodium, 1 part of azobactam sodium, 3-18 parts of liposome film material, 1.2-10 parts of addictive, 6-25 parts of frozen-dried support agent and 0.1-4 parts of antioxidant. By preparing the ceftriaxone sodium tazobactam sodium medicinal composition into liposome, the stability of a preparation can be greatly improved, the quality of medicines is improved, the toxic or side effects are reduced, the target property can be acquired and the curative effect can be improved.

Description

technical field [0001] The invention relates to a ceftriaxone sodium tazobactam sodium pharmaceutical composition liposome injection and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] Ceftriaxone Sodium (Ceftriaxone, Junbizhi), is a semi-synthetic third-generation cephalosporin, which is effective against G + Bacteria have moderate antibacterial effect on G - The main sensitive bacteria are Staphylococcus aureus, Streptococcus, Streptococcus pneumoniae, Haemophilus, Neisseria, Escherichia coli, Klebsiella pneumoniae, Serratia, various types of Proteus, citrate Citrobacter, Salmonella typhi, Shigella, Peptococcus, Peptostreptococcus, Clostridium, etc. [0003] Clinically, the curative effect of ceftriaxone sodium on lower respiratory tract infection is relatively satisfactory, the clinical effective rate is 75%-100%, and the bacterial clearance rate is generally above 90%. The primary lesion is different, ...
