Meropenem – Broad-Spectrum Carbapenem Antibiotic (Rx)

Meropenem is a broad-spectrum carbapenem antibiotic used for the treatment of serious and complicated bacterial infections. It works by inhibiting bacterial cell wall synthesis, leading to rapid bacterial cell death. Due to its wide coverage against Gram-positive, Gram-negative, and anaerobic organisms, meropenem is commonly reserved for severe or resistant infections.

It is frequently used in hospital settings for conditions such as intra-abdominal infections, meningitis, sepsis, pneumonia, and complicated skin or urinary tract infections.
