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.

This product is a first-generation cephalosporin with a broad antibacterial spectrum and strong activity against Gram-positive bacteria. Penicillinase-producing and non-penicillinase-producing Staphylococcus aureus, coagulase-negative Staphylococcus, Streptococcus pyogenes, Streptococcus pneumoniae, Group B hemolytic Streptococcus, Streptococcus viridans, Staphylococcus epidermidis, Corynebacterium diphtheriae, and Bacillus anthracis are all quite sensitive to this product. Enterococci, methicillin-resistant Staphylococcus, Listeria, and Nocardia are resistant. Haemophilus influenzae, Neisseria meningitidis, Moraxella catarrhalis, and Neisseria gonorrhoeae are highly sensitive to this product. Some strains of Escherichia coli, Klebsiella, Salmonella, Shigella, and Proteus are moderately sensitive to this product, while most of the other Gram-negative rods are resistant. Gram-positive anaerobic bacteria are sensitive to this product, and Bacteroides fragilis is resistant to this product. This product mainly inhibits the synthesis of bacterial cell walls.
