Used to treat a wide range of bacterial infections, including respiratory tract infections, urinary tract infections, skin infections, and intra-abdominal infections. Effective against meningitis, particularly in children, due to its ability to penetrate the blood-brain barrier. Commonly used in surgical prophylaxis to prevent infections during and after procedures. Administered intravenously or intramuscularly, it is favored for its long half-life, allowing once-daily dosing. Also used in the treatment of gonorrhea and Lyme disease, especially in cases involving the central nervous system.
