Kill bacteria by inhibiting cell wall synthesis, and due to the structural characteristics of this product, it has a high resistance to beta-lactamase produced by bacteria. The following common clinical Gram-positive, Gram-negative aerobic and anaerobic pathogens are highly sensitive to this product

Kills bacteria by inhibiting cell wall synthesis. It is highly resistant to beta-lactamase produced by bacteria and is highly sensitive to Gram-positive, Gram-negative aerobic and anaerobic pathogens.

Cefepime is a broad-spectrum fourth-generation cephalosporin that achieves bactericidal effects by inhibiting the biosynthesis of bacterial cell walls. In vitro tests have shown that this product is effective against both Gram-positive and Gram-negative bacteria. This product has low affinity for beta-lactamase encoded by bacterial chromosomes, is highly resistant to hydrolysis by most beta-lactamases, and can quickly penetrate into the cells of Gram-negative bacteria. In bacterial cells, its target molecule is penicillin-binding protein (PBP). In vitro and clinical studies have confirmed that this product is active against most of the following microorganisms. Gram-negative aerobic microorganisms: Enterobacter, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa. Gram-positive aerobic microorganisms: Staphylococcus aureus (only for methicillin-sensitive strains), Streptococcus pyogenes (Group A streptococci), Streptococcus pneumoniae. This product is active against most of the following microorganisms in vitro, but there is no sufficient and strict support for the treatment of clinical infectious diseases. Gram-negative aerobic microorganisms: Acinetobacter calcoaceticus, Citrobacter freundii, Citrobacter heteromorphus, Enterobacter agglomerans, Haemophilus influenzae (including beta-lactamase-producing strains), Hafnia alvei, Klebsiella occidentalis, Moracata (including beta-lactamase-producing strains), Proteus vulgaris, Proteus rettii, Providencia stuartii, Serratia marcescens. This product is inactive against most strains of oligotrophomonas. Gram-positive aerobic microorganisms: Staphylococcus epidermidis (only for methicillin-sensitive strains), Staphylococcus saprophyticus, Streptococcus agalactiae (group B streptococci). Most enterococci, such as Enterococcus faecalis and methicillin-resistant Staphylococci, are resistant to this product. Anaerobic microorganisms: Gram-negative rods (including Bacteroides fragilis, other Bacteroides and Fusobacterium species), Gram-positive and Gram-negative cocci (including Peptococcus, Peptostreptococcus and Veillonella species), Gram-positive rods (including Clostridium, Eubacterium and Lactobacillus species).
