Acute toxicity LD50 mice (mg/kg):225 intravenous; 1000 oral; Rats (g/kg):1.5 intraperitoneal injection; 2.5 oral. Pefloxacin Mesylate: C17H20FN3O3? CH3SO3H? 2H2O. [149676-40-4]. White to yellowish crystalline powder, a few odorless, slightly bitter taste. Soluble in water, ethanol-soluble, a few insoluble in ether. |
| Use | The third generation of quinolone antibacterial drugs, has a broad spectrum of antibacterial effect, the antibacterial spectrum and antibacterial activity and norfloxacin similar. The bacteria are inhibited or killed by interfering with the replication of DNA and the synthesis of bacterial proteins. It has a strong antibacterial effect on Staphylococcus aureus, and has a very strong antibacterial effect on a variety of gram-negative bacteria and strains resistant to ampicillin and TMP cephalosporin V, it is as effective against intestinal bacteria as third-generation cephalosporins, but less effective against anaerobes, tubercle bacilli, and Clostridia. It is not easy to produce drug resistance. For sepsis, bacterial meningitis, respiratory tract, urinary tract, kidney, liver and gallbladder, gynecological diseases, bone and joint infections. |
