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.

It exerts antibacterial activity by inhibiting the synthesis of bacterial cell walls and has antibacterial activity against aerobic Gram-positive bacteria (such as Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes) and aerobic Gram-negative bacteria (such as Escherichia coli, Klebsiella pneumoniae, Proteus)

It exerts its antibacterial activity by inhibiting the synthesis of bacterial cell walls, and has antibacterial activity against aerobic Gram-positive bacteria (such as Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes) and aerobic Gram-negative bacteria (such as Escherichia coli, Klebsiella pneumoniae, Proteus).

It has good antibacterial effect on hemolytic streptococci and other streptococci, Streptococcus pneumoniae and non-penicillinase-producing staphylococci. It has moderate antibacterial effect on enterococci. Neisseria gonorrhoeae, Neisseria meningitidis, Corynebacterium diphtheriae, Bacillus anthracis, Actinomyces bovis, Streptobacillus candida, Listeria monocytogenes, Leptospira and Treponema pallidum are sensitive to this product. It also has certain antibacterial activity against Haemophilus influenzae and Bordetella pertussis, and other Gram-negative aerobic or facultative anaerobic bacteria are less sensitive to this product. It has good antibacterial effect on Clostridium, peptostreptococcal anaerobes and melanin-producing Bacteroides, but poor antibacterial effect on Bacteroides fragilis. Penicillin exerts its bactericidal effect by inhibiting bacterial cell wall synthesis.
