Cefazolin is widely used in the medical field as a first-generation cephalosporin antibiotic. It is primarily administered intravenously or intramuscularly to treat a variety of bacterial infections. Its applications include preventing infections during surgical procedures, particularly in orthopedic, cardiovascular, and abdominal surgeries. It is effective against skin infections, respiratory tract infections, urinary tract infections, and septicemia. Cefazolin is also commonly used to treat bone and joint infections caused by susceptible bacteria. Due to its broad-spectrum activity, it is often the first choice for prophylaxis in clean and clean-contaminated surgeries.
