Third-generation cephalosporins are commonly used, including cefixime, cefotaxime, and ceftriaxone. Cephalosporins are divided into five generations, the first generation is now less commonly used, the market is commonly used in the second and third generation, the second and third generation are characterized by increased effect on gram-negative bacteria. The fourth and fifth generations not only have strong antibacterial effects on gram-negative and gram-positive bacteria, but also have less nephrotoxicity and side effects, making them more advanced cephalosporins. Clinically used to control most of the disease is the second and third generation, the third generation used more, such as common ceftriaxone, cefixime, are the third generation of cephalosporins. Drugs from different manufacturers have different trade names, so you should pay attention to the distinction when buying drugs. The main feature of third-generation cephalosporins is that the antibacterial spectrum is broader than that of previous cephalosporins, and it can control most gynecological infections as well as respiratory infections at present, and the side effects are not big.
