Ampicillin sodium is a broad-spectrum semi-synthetic penicillin. It has strong antibacterial effects on hemolytic streptococci, pneumococci 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.

The antibacterial spectrum is broader than that of ampicillin and carbenicillin, and it has high activity against both Gram-positive bacteria (including anaerobic cocci and bacilli) and Gram-negative bacteria. Its antibacterial effect is 7 to 10 times stronger than that of carbenicillin against mouse infection caused by Pseudomonas aeruginosa, 2 to 15 times stronger against Escherichia coli, 8 times stronger against Klebsiella pneumoniae, and 2 times stronger against hemolytic Streptococcus.
