Doripenem is primarily used as a broad-spectrum antibiotic to treat severe bacterial infections. It is effective against a wide range of Gram-positive and Gram-negative bacteria, making it suitable for complicated intra-abdominal infections, urinary tract infections, and pneumonia, particularly those acquired in hospital settings. Its ability to resist degradation by many beta-lactamases enhances its efficacy against resistant bacterial strains. Doripenem is often administered intravenously in hospital environments, especially for patients who have not responded to other antibiotics or are at risk of multi-drug resistant infections. It is also utilized in post-surgical infections and severe cases where rapid bacterial eradication is critical. Careful monitoring is required to ensure appropriate use and to minimize the risk of antibiotic resistance.
