Meropenem is a broad-spectrum, powerful antibiotic belonging to the carbapenem class. It is used to treat serious bacterial infections by inhibiting cell wall synthesis, effectively killing a wide range of gram-positive and gram-negative bacteria, including resistant strains. Commonly prescribed for severe infections such as pneumonia, sepsis, meningitis, and intra-abdominal infections, meropenem is typically administered intravenously in hospital settings.
