This product belongs to the third generation of cephalosporin, with broad-spectrum antibacterial effect, and is stable to the broad-spectrum beta-lactamase produced by various Gram-positive and Gram-negative bacteria. It has a strong antibacterial effect on Enterobacteriaceae such as Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis. Pseudomonas and Acinetobacter species such as Pseudomonas aeruginosa are less sensitive to this product. It has a good antibacterial effect on Haemophilus influenzae and Neisseria gonorrhoeae. The effect on Staphylococcus aureus and Staphylococcus epidermidis is worse than that of the first and second generation cephalosporins. Methicillin-resistant Staphylococcus aureus and Enterococcus are resistant to this product, and various streptococci are highly sensitive to this product. Anaerobic bacteria such as Peptococcus, Peptostreptococcus and some Bacteroides are mostly sensitive to this product, and Clostridium difficile is resistant to this product. The mechanism of action is to achieve bactericidal effect by inhibiting the biosynthesis of bacterial cell wall mucopeptides.

This product has a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacilli. It has good antibacterial activity in vitro against the following bacteria: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. It often has antibacterial activity against multi-drug resistant bacteria. It has high antibacterial activity against penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae and Moraxella. It has antibacterial activity against most strains of Pseudomonas such as Pseudomonas aeruginosa. This product has antibacterial activity against methicillin-sensitive Staphylococcus aureus, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good antimicrobial activity against Chlamydia trachomatis, Mycoplasma, Legionella, and also has antibacterial activity against Mycobacterium tuberculosis and atypical mycobacteria. The antibacterial activity against anaerobic bacteria is poor. Enoxacin is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death.
