Doripenem 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, particularly those resistant to other antibiotics. Doripenem works by inhibiting bacterial cell wall synthesis, effectively killing the bacteria. This medication is often prescribed for complicated infections, such as intra-abdominal infections and pneumonia. It is typically administered intravenously in a hospital setting. As with all antibiotics, it is important to use Doripenem only when necessary to help prevent antibiotic resistance.
