Cephalothin sodium salt is primarily used as an antibiotic in the medical field. It is effective against a wide range of bacterial infections, particularly those caused by gram-positive organisms. It is often administered intravenously or intramuscularly to treat serious infections such as respiratory tract infections, urinary tract infections, skin and soft tissue infections, and septicemia. The drug works by inhibiting the synthesis of bacterial cell walls, leading to the destruction of the bacteria. It is also used in surgical prophylaxis to prevent infections during and after surgical procedures. Due to its broad-spectrum activity, it has been a valuable tool in managing infections in both hospital and community settings.
