The second generation cephalosporin antibiotics have similar or slightly worse antibacterial activity against Gram-positive cocci than the first generation cephalosporins, but are quite stable against β-lactamase produced by Staphylococci and Gram-negative bacilli. Methicillin-resistant Staphylococci, Enterococci and Listeria are resistant, and other positive cocci (including anaerobic cocci) are sensitive to this product. The antibacterial activity against Staphylococcus aureus is worse than that of cefazolin, and 1-2 mg/L can inhibit all Staphylococcus aureus that are sensitive and resistant to penicillin, respectively. It has strong antibacterial activity against Haemophilus influenzae, and Escherichia coli, Proteus mirabilis, etc. may be sensitive to this product; indole-positive Proteus, Citrobacter and Acinetobacter are poorly sensitive to this product, Serratia is mostly resistant, Pseudomonas aeruginosa, Campylobacter and Bacteroides fragilis 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.

This product belongs to the lincomycin antibiotics, which is a derivative of lincomycin. Its antibacterial spectrum is the same as that of lincomycin, and its antibacterial activity is 4 to 8 times stronger than that of lincomycin. It has high antibacterial activity against Gram-positive bacteria such as Staphylococcus (including penicillin-resistant strains), Streptococcus, Corynebacterium diphtheriae, Bacillus anthracis, etc. It also has good antibacterial activity against Gram-negative anaerobic bacteria. Most of the Bacteroides, including Bacteroides fragilis, Fusobacterium, Peptococcus, Peptostreptococcus, and Clostridium perfringens, are highly sensitive to this product. Gram-negative aerobic bacteria, including Haemophilus influenzae, Neisseria, and Mycoplasma, are resistant to this product. There is no cross-resistance between this product and penicillin, chloramphenicol, cephalosporins, and tetracyclines, but it has partial cross-resistance with macrolides and complete cross-resistance with lincomycin. The mechanism of action of this product is to bind to the 50S subunit of the bacterial ribosome, prevent the elongation of the peptide chain, and thus inhibit the protein synthesis of bacterial cells. This product is an antibacterial drug, but at high concentrations, it also has a bactericidal effect on certain bacteria.
