Used as a broad-spectrum antibiotic in the treatment of various bacterial infections, particularly those caused by Gram-negative and Gram-positive organisms. It is effective in treating respiratory tract infections, urinary tract infections, skin and soft tissue infections, intra-abdominal infections, and septicemia. Often combined with a beta-lactamase inhibitor like tazobactam to enhance its stability against bacterial enzyme degradation, allowing it to remain active against resistant strains. Commonly administered intravenously in hospital settings for severe infections.
