This product is an oral third-generation broad-spectrum cephalosporin antibiotic. This product has strong antibacterial activity against Gram-positive bacteria such as Streptococcus (except faecal Streptococcus) and Streptococcus pneumoniae; Gram-negative bacteria such as Escherichia coli, Haemophilus influenzae, Klebsiella, Salmonella, Shigella, and Neisseria gonorrhoeae, especially against Serratia, indole-positive Proteus, Enterobacter, and Citrobacter, which are less sensitive to cephalosporins. It is stable to β-lactamase produced by bacteria. However, this product is ineffective against drug-resistant microorganisms such as Pseudomonas, Mycoplasma, Chlamydia, and Enterococcus.

This product is a cephalosporin antibiotic, which has a good antibacterial effect on Gram-positive bacteria, and also has a certain antibacterial activity against Gram-negative bacteria and some anaerobic bacteria. This product has a good antibacterial effect on Gram-positive bacteria and some Gram-negative bacteria except enterococci. For example, penicillinase-producing and non-penicillinase-producing Staphylococcus aureus, Staphylococcus epidermidis, pneumococcus, group A hemolytic streptococci, Escherichia coli, and Proteus mirabilis are sensitive to this product; this product also has antibacterial effects on Salmonella, Shigella, Haemophilus influenzae, Neisseria gonorrhoeae, etc. Methicillin-resistant Staphylococci, Enterococci, indole-positive Proteus, Enterobacter, Serratia, and Pseudomonas aeruginosa are resistant to this product. Its mechanism of action is to bind to penicillin-binding proteins (PBPs) on the bacterial cell membrane, acylate the transpeptidase, inhibit the synthesis of the bacterial septum and cell wall, affect the cross-linking of the cell wall mucopeptide components, inhibit cell division and growth, elongate the bacterial morphology, and finally dissolve and die.

Broad-spectrum antibiotics, generally have good antibacterial effects on Gram-positive bacteria, and also have certain antibacterial activity against Gram-negative bacteria and some anaerobic bacteria

The first generation of oral cephalosporin has good antibacterial effect on most strains of penicillinase-producing and non-penicillinase-producing Staphylococcus aureus, coagulase-negative Staphylococcus, Streptococcus pneumoniae, group A hemolytic Streptococcus, etc. It also has certain antibacterial activity against Escherichia coli, Proteus mirabilis, Salmonella, Shigella, Haemophilus influenzae and gonococci. Methicillin-resistant Staphylococcus, Enterococcus, indole-positive Proteus, Enterobacter, Serratia and other Enterobacteriaceae, Pseudomonas aeruginosa and Bacteroides fragilis are resistant to this product.
