Ticarcillin is a broad-spectrum penicillin bactericide. It has a broad-spectrum bactericidal effect when combined with clavulanic acid. It is suitable for the empirical treatment of a wide range of bacterial infectious diseases. The in vitro antibacterial spectrum includes a variety of Gram-positive and Gram-negative bacteria, aerobic bacteria and anaerobic bacteria.

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

This product is a semi-synthetic penicillin, which has good antibacterial effect on Gram-positive bacteria, Gram-negative bacteria and Pseudomonas aeruginosa. It can produce synergistic effect when used in combination with amikacin, gentamicin and netilmicin.

Piperacillin is a semi-synthetic penicillin antibiotic with a broad-spectrum antibacterial effect. It has good antibacterial effects on Enterobacteriaceae such as Escherichia coli, Proteus, Serratia, Klebsiella, Enterobacter, Citrobacter, Salmonella and Shigella, as well as other Gram-negative bacteria such as Pseudomonas aeruginosa, Acinetobacter, Haemophilus influenzae and Neisseria. It also has certain antibacterial activity against Enterococci, Group A and Group B hemolytic streptococci, Streptococcus pneumoniae and Staphylococci that do not produce penicillinase. Many anaerobic bacteria, including Bacteroides fragilis and Clostridium, are also sensitive to piperacillin. The mechanism of action of piperacillin is to exert a bactericidal effect by inhibiting bacterial cell wall synthesis.
