CEFTRIAXONE Uses And Synthesis

Ceftriaxone Sodium (Rocephin) is a third-generation cephalosporin antibiotic. Like other third-generation cephalosporins, it can resist gram-positive and gram-negative bacteria. In most cases, it is considered to be the same as cefotaxime in terms of safety and effectiveness. It is used for lower respiratory tract infections, urinary tract infections, biliary tract infections caused by sensitive pathogenic bacteria, as well as abdominal cavity infections, pelvic infections, skin and soft tissue infections, bone and joint infections, sepsis, meningitis, etc. and the prevention of surgical infections. Similar drugs include cefotaxime, ceftriaxone, aminothiatriazine, cephalosporin, ceftexone and so on.
