This product is an antibiotic drug. Except for enterococci, methicillin-resistant and penicillin-resistant Staphylococcus aureus, it has good antibacterial activity against other Gram-positive cocci. Pneumococci and lytic streptococci are highly sensitive to this product. Diphtheria Corynebacterium, anthrax Bacillus, Listeria and Clostridium are sensitive to this drug. This product has stronger antibacterial activity against Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae than cephalothin and cefotaxime, but its antibacterial effect against Pseudomonas aeruginosa is worse than the latter two. Salmonella typhi and Shigella are sensitive to this drug, while other Enterobacteriaceae, Acinetobacter and Pseudomonas aeruginosa and Bacteroides fragilis are resistant. Neisseria is quite sensitive to this product, while influenza bacilli are only moderately sensitive.

This product has stronger antibacterial activity against Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae than cephalothin and cefotaxime, but its antibacterial effect against high-content bacteria is poorer than the latter two. Salmonella typhi and Shigella are sensitive to this drug, while other Enterobacteriaceae, Acinetobacter and Pseudomonas aeruginosa and Bacteroides fragilis are resistant. Neisseria is quite sensitive to this product, while influenza bacilli are only moderately sensitive.

It kills bacteria by inhibiting bacterial cell wall synthesis and has high resistance to β-lactamase produced by bacteria. Some common Gram-positive, Gram-negative aerobic and anaerobic pathogens are highly sensitive to this product. It is resistant to Pseudomonas aeruginosa, most strains of enterococci, and Escherichia coli.

This product is a first-generation cephalosporin, which has good antibacterial effect on some strains of Gram-positive cocci such as non-penicillinase-producing and penicillinase-producing Staphylococcus aureus, coagulase-negative Staphylococci, group A hemolytic streptococci, Streptococcus pneumoniae and viridans streptococci. Anaerobic Gram-positive bacteria are mostly sensitive to this product, while Bacteroides fragilis is resistant to it. Methicillin-resistant Staphylococci and Enterococci are resistant to this product. The effect of this product on Gram-positive and Gram-negative bacteria is similar to that of cephalexin. This product has a certain effect on gonococci and is also active against enzyme-producing gonococci; its activity against Haemophilus influenzae is poor.
