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.

This product is an acid-resistant and penicillinase-resistant penicillin. It has good antibacterial activity against penicillinase-producing Staphylococci, but its antibacterial activity against various streptococci and non-penicillinase-producing Staphylococci is inferior to penicillin G. This product exerts its bactericidal effect by inhibiting bacterial cell wall synthesis.

Broad-spectrum penicillin antibiotics, which can be hydrolyzed by β-lactamase. When used in combination with potassium clavulanate, its antibacterial spectrum is expanded, and it has good effects on enzyme-producing Staphylococcus aureus, Staphylococcus epidermidis, coagulase-negative Staphylococci and enterococci. It also has good antibacterial activity against certain β-lactamase-producing Enterobacteriaceae, Haemophilus influenzae, Moraxella catarrhalis, Bacteroides fragilis, etc.

It has only weak antibacterial activity itself, but has a strong broad-spectrum β-lactamase inhibitory effect, which can protect amoxicillin from β-lactamase hydrolysis.

Ticarcillin is a broad-spectrum bactericidal agent of the penicillin class. When combined with clavulanic acid, it becomes an antibiotic with broad-spectrum bactericidal effect. It is suitable for the empirical treatment of a wide range of bacterial infectious diseases.

Clavulanic acid is an irreversible and highly effective β-lactamase inhibitor. It has little antibacterial effect alone. It restores ticarcillin sensitivity by blocking β-lactamase. When combined with ticarcillin, this product becomes an antibiotic with broad-spectrum bactericidal effect.

This product has a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacilli. It has good antibacterial activity in vitro against the following bacteria: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. It often has antibacterial activity against multi-drug resistant bacteria. It has high antibacterial activity against penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae and Moraxella. It has antibacterial activity against most strains of Pseudomonas such as Pseudomonas aeruginosa. This product has antibacterial activity against methicillin-sensitive Staphylococcus aureus, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good antimicrobial activity against Chlamydia trachomatis, Mycoplasma, Legionella, and also has antibacterial activity against Mycobacterium tuberculosis and atypical mycobacteria. The antibacterial activity against anaerobic bacteria is poor. Enoxacin is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death.
