This product is a semi-synthetic penicillin, which is acid-resistant and penicillinase-resistant. It has antibacterial activity against Gram-positive cocci and Neisseria. Its antibacterial activity against enzyme-producing strains of Staphylococcus (including Staphylococcus aureus and coagulase-negative Staphylococci) is stronger than that of oxacillin, but its antibacterial effect against penicillin-sensitive Staphylococci and various streptococci is weaker than that of penicillin, and it is ineffective against methicillin-resistant Staphylococci.

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.

Ampicillin sodium is a broad-spectrum semi-synthetic penicillin. This product has a strong antibacterial effect on hemolytic streptococci, Streptococcus pneumoniae and non-penicillinase-producing Staphylococci, which is similar to or slightly inferior to penicillin. Ampicillin also has a good antibacterial effect on viridans streptococci, and is better than penicillin on enterococci and Listeria. This product has antibacterial activity against Corynebacterium diphtheriae, Bacillus anthracis, Actinomyces, Haemophilus influenzae, Bordetella pertussis, Neisseria and anaerobic bacteria except Bacteroides fragilis. Some Proteus mirabilis, Escherichia coli, Salmonella and Shigella are sensitive to this product. Ampicillin exerts its bactericidal effect by inhibiting bacterial cell wall synthesis.
