What are cephalosporin anti-inflammatory drugs? Cephalosporins can be divided into four generations. Let's take a closer look. Cephalosporins: 1. Cefazolin (Xianfeng No.5) and cefradine (Xianfeng No.6) are used to inject the first generation cephalosporins, and cefalexin (Xianfeng No.4), cefradine (Xianfeng No.6) and cefadroxil are taken orally. Suitable for respiratory tract, skin and soft tissue, urogenital tract infection, etc. 2. Compared with the first generation, the second generation cephalosporins have wider antibacterial spectrum, stronger antibacterial effect and lower nephrotoxicity. Cefuroxime, Cefmondo, Cefoxitin and Cefmetazole for injection, and Cefuroxime axetil and Cefmclo for oral use. 3. The third generation cephalosporins have the characteristics of broad antibacterial spectrum, strong antibacterial activity, wide distribution in the body and low toxicity to human body. Cefotaxime for injection, ceftazidime, ceftriaxone, cefoperazone, ceftizoxime and cefodizime for oral use. Cefpodoxime axetil, cefteram axetil, cefetamet axetil, etc. Can be used for respiratory tract, skin and soft tissue, urogenital system, gastrointestinal tract infection and septicemia. 4. The fourth generation cephalosporin is superior to the first three generations because of its special mode of action and extensive antibacterial spectrum. Because there is little possibility of cross-allergy with penicillin, it can be used for patients who are allergic to penicillin. At present, there are cefepime and pilocarpine for injection on the market.
