Cefoselis sulfate is primarily used as a broad-spectrum antibiotic in the medical field. It is effective against a variety of bacterial infections, particularly those caused by Gram-positive and Gram-negative bacteria. This compound is often administered intravenously in hospital settings to treat severe infections such as sepsis, pneumonia, and complicated urinary tract infections. Its ability to penetrate bacterial cell walls and inhibit cell wall synthesis makes it a valuable option in combating resistant bacterial strains. Additionally, cefoselis sulfate is utilized in postoperative care to prevent infections in surgical patients, ensuring a lower risk of complications. Its use is carefully monitored due to potential side effects, including allergic reactions and impacts on kidney function.
