Meropenem is a broad-spectrum antibiotic belonging to the class of medications known as carbapenems. It is primarily used to treat serious infections caused by bacteria that are resistant to other antibiotics. Meropenem works by inhibiting bacterial cell wall synthesis, leading to the death of the bacteria. This medication is often prescribed for infections in the lungs, skin, and abdominal area, as well as for certain types of meningitis. It is typically administered intravenously in a hospital setting, allowing for quick action against severe bacterial infections.
