Competitive irreversible broad-spectrum β-lactamase inhibitor, which protects amoxicillin from destruction by effectively inhibiting β-lactamase produced by bacteria. It is effective against a variety of Gram-positive and Gram-negative bacteria, including penicillin-resistant and some methicillin-resistant strains, and can be used for infections caused by resistant bacteria.

It is a bactericidal broad-spectrum antibiotic that has a good synergistic effect when combined with sulbactam pivoxil. It is effective against a variety of Gram-positive and Gram-negative bacteria, including Staphylococcus aureus, Pneumococcus, Escherichia coli, Haemophilus influenzae, etc.

This product has a broad-spectrum antibacterial effect, and has a certain antibacterial effect on most bacteria of the Enterobacteriaceae family, including Escherichia coli, Klebsiella, Proteus, Shigella, Typhoid and Salmonella, as well as Haemophilus influenzae, Neisseria, etc. It also has a certain antibacterial effect on Pseudomonas aeruginosa and Staphylococcus aureus, and has only a slight effect on Pneumococcus, various groups of Streptococcus and Enterococcus. In addition, it also has antibacterial activity against Mycobacterium leprae. Pefloxacin mesylate is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibits DNA synthesis and replication, and causes bacterial death.

It is a semi-synthetic broad-spectrum penicillin antibiotic that mainly acts on the bacterial reproduction stage by inhibiting the biosynthesis of cell wall mucopolypeptides. It is effective against many Gram-positive and Gram-negative bacteria.

It has a β-lactam structure similar to penicillin and has only weak antibacterial activity itself, but it can inactivate enzymes produced by many bacteria by blocking the active site of β-lactamase, especially for clinically important plasmid-mediated β-lactamase. It can protect amoxicillin from hydrolysis and destruction by β-lactamase, so it is still effective against resistant bacteria that produce β-lactamase.

This product is a penicillin antibiotic, which has good antibacterial activity against Streptococcus such as Streptococcus pneumoniae and hemolytic Streptococcus, aerobic Gram-positive cocci such as non-penicillinase-producing Staphylococcus and Enterococcus faecalis, aerobic Gram-negative bacteria such as Escherichia coli, Proteus mirabilis, Salmonella, Haemophilus influenzae, Neisseria gonorrhoeae, and Helicobacter pylori. Amoxicillin exerts its bactericidal effect by inhibiting the synthesis of bacterial cell walls, which can quickly dissolve and rupture bacteria into spherical bodies.
