Used in the treatment of severe bacterial infections, particularly those caused by Gram-negative bacteria, including respiratory tract infections, urinary tract infections, skin and soft tissue infections, and sepsis. Effective against multi-drug resistant strains due to its broad-spectrum activity. Commonly administered in hospital settings for patients requiring intravenous antibiotics. Often chosen when other antibiotics fail due to resistance. Stable against many beta-lactamases, making it suitable for complicated infections.
