Meropenem is a synthetic broad-spectrum carbapenem antibiotic that produces antibacterial effects by inhibiting the synthesis of bacterial cell walls. It is effective against most Gram-positive and Gram-negative bacteria, including Streptococcus pneumoniae, Streptococcus viridans, Escherichia coli, Haemophilus influenzae, Klebsiella pneumoniae, Pseudomonas aeruginosa, Neisseria meningitidis, Bacteroides fragilis, Bacteroides thetaiotaomicron and Peptostreptococcus. It is stable to most β-lactamases, but is not suitable for the treatment of methicillin-resistant Staphylococcus infections.

This product is a second-generation cephalosporin antibiotic. Its effect on Gram-positive bacteria is similar to that of cefazolin, but it is more effective against Gram-negative bacteria, such as Haemophilus, Escherichia coli, Klebsiella, Proteus mirabilis, etc. It also has antibacterial effects on Enterobacter, Citrobacter, indole-positive Proteus, etc. Its mechanism of action is to bind to penicillin-binding proteins (PBPs) on the bacterial cell membrane, acylate transpeptidase, inhibit the synthesis of bacterial septum and cell wall, affect the cross-linking of cell wall mucopeptide components, inhibit cell division and growth, elongate the bacterial morphology, and finally dissolve and die.
