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.

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.

It is a broad-spectrum semi-synthetic penicillin, which has a broad-spectrum killing effect on Gram-positive and Gram-negative bacteria. It has a strong antibacterial effect on hemolytic streptococci, pneumococci and non-penicillinase-producing staphylococci, which is similar to or slightly inferior to penicillin. It also has a good antibacterial effect on viridans streptococci, and is better than penicillin on enterococci and Listeria. It has antibacterial effects on Corynebacterium diphtheriae, Bacillus anthracis, Actinomyces, Haemophilus influenzae, Bordetella pertussis and Neisseria.

It is an acid-resistant and enzyme-resistant semi-synthetic penicillin that is effective against penicillin-resistant Staphylococcus aureus. When used in combination with ampicillin, they can enhance the effects of each other and make up for the shortcomings of each used alone.
