This product is a β-lactamase-stable cephalosporin bactericidal antibiotic that works by blocking the synthesis of the main cell wall polymer - peptidoglycan, and has a broad-spectrum bactericidal effect on Gram-negative and Gram-positive pathogens.

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 high-content bacteria is weaker 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.

Cefazolin is a first-generation cephalosporin with a broad antibacterial spectrum. Except for Enterococcus and methicillin-resistant Staphylococcus, this product has good antibacterial activity against other Gram-positive cocci, and Streptococcus pneumoniae and hemolytic Streptococcus are highly sensitive to this product. Diphtheria Corynebacterium, anthrax Bacillus, Listeria and Clostridium are also very sensitive to this product. This product has good antibacterial activity against some Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae, but has poor antibacterial effect on Staphylococcus aureus. Salmonella typhi, Shigella and Neisseria are sensitive to this product, while other Enterobacteriaceae, Acinetobacter and Pseudomonas aeruginosa are resistant. Enzyme-producing Neisseria gonorrhoeae is resistant to this product; Haemophilus influenzae is only moderately sensitive. Gram-positive anaerobes and some Gram-negative anaerobes are mostly sensitive to this product. Bacteroides fragilis is resistant.
