Abstract

The invention discloses a composition used for inhibiting bacteria generating novel beta lactamase. The composition is advantaged in that the active components of the composition comprise cefepime and tazobactam with a weight ratio of 2-6:1. According to the invention, the composition used for inhibiting the bacteria generating novel beta lactamase has a good inhibiting and / or killing effect against the bacteria generating novel CTX-M enzyme and AmpC enzyme, and is especially effective against bacteria with drug resistance to CTX-M enzyme and AmpC enzyme hydrolysis effects. The composition has good practicality, and provides good economic and social effects.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a composition against bacteria producing novel beta-lactamases (such as CTX-M enzyme and AmpC enzyme). Background technique [0002] Drug-resistant bacterial infection has become a major problem in the clinical treatment of infectious diseases. The fourth-generation cephalosporin cefepime has antibacterial activity against both Gram-negative bacilli and Gram-positive cocci, including Enterobacter cloacae, Enterobacter aerogenes, Klebsiella pneumoniae, Serratia, and Escherichia cocci bacteria, Pseudomonas aeruginosa, Proteus mirabilis, Proteus vulgaris, Enterobacter agglomerans, Citrobacter, Acinetobacter, Haemophilus influenzae (including β-lactamase producing strains) and Haemophilus parainfluenzae , Moraxella catarrhalis (including producing β-lactamase), etc.; Gram-positive cocci include Streptococcus pneumoniae (including penicillin-resistant bacteria), Streptococcus pyogen...
