Doripenem monohydrate is primarily used as a broad-spectrum antibiotic in the treatment of severe bacterial infections. It is particularly effective against Gram-negative and Gram-positive bacteria, including multidrug-resistant strains. This compound is commonly administered in hospital settings for infections such as complicated intra-abdominal infections, complicated urinary tract infections, and nosocomial pneumonia, including ventilator-associated pneumonia. Its ability to penetrate tissues and resist degradation by many beta-lactamases makes it a valuable option in critical care. Doripenem monohydrate is typically given intravenously, ensuring rapid and effective delivery to combat life-threatening infections. Its use is often reserved for cases where other antibiotics have failed or are unsuitable due to resistance patterns.
