Used as a broad-spectrum antibiotic in clinical settings to treat severe bacterial infections, particularly those caused by multidrug-resistant organisms. Effective against both Gram-positive and Gram-negative bacteria, including anaerobes. Commonly prescribed for intra-abdominal infections, respiratory tract infections, and urinary tract infections when other antibiotics fail. Administered intravenously in hospital environments due to its stability against beta-lactamases, making it valuable in treating infections with limited therapeutic options.
