Amoxicillin is a penicillin antibiotic that has good antibacterial activity against Streptococcus such as Streptococcus pneumoniae and hemolytic Streptococcus, aerobic Gram-positive cocci such as non-penicillinase-producing Staphylococci 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.

It is a semi-synthetic penicillin antibiotic that has antibacterial effects on sensitive strains of Gram-negative bacteria, Gram-positive bacteria and anaerobic bacteria.

It is a β-lactamase inhibitor that can enhance the antibacterial activity of piperacillin against β-lactamase-producing bacteria.

It is a semi-synthetic penicillin antibiotic that has antibacterial effects on piperacillin-sensitive bacteria and beta-lactamase-producing piperacillin-resistant bacteria, including a variety of Gram-negative bacteria, Gram-positive bacteria and anaerobic bacteria.

It is a beta-lactamase inhibitor. Its combination with piperacillin can enhance its antibacterial spectrum, especially against beta-lactamase-producing resistant strains.

It is a semi-synthetic penicillin antibiotic that has antibacterial effects on Gram-negative and Gram-positive bacteria, and can fight against bacteria that produce and do not produce beta-lactamase.

It is a beta-lactamase inhibitor. Its combination with piperacillin can enhance its antibacterial activity, especially against beta-lactamase-producing resistant bacteria.
