Meropenem is a carbapenem antibiotic for parenteral use. It is structurally similar to imipenem but is stable to human dehydropeptidase-1 (DHP-1). It shows potent bactericidal activity against a broad spectrum of Gram-positive and Gram-negative, aerobic and anaerobic bacteria as it can penetrates bacterial cell wall excellently, it has high level of stability to all serine ß-lactamases and it has marked affinity for the Penicillin Binding Proteins (PBPs).

As with other antibiotics, caution may be required in using Meropenem as monotherapy in critically ill patients with known or suspected Pseudomonas aeruginosa lower respiratory tract infection. Regular sensitivity testing is recommended when treating Pseudomonas aeruginosa infection.
