| 产品描述 | MIC: from<0.025 to 25 μg/ml for E. coli, K. pneumoniae, and H. influenzae Cefixime is a third generation cephalosporin antibiotic. The cephalosporins, a class of β-lactam antibiotics, are originally derived from the fungus Acremonium. In vitro: Previous study found that cefixime was more active than cephalexin, cefaclor, and amoxicillin against various gram-negative bacteria. Cefixime was also significantly more active than tested reference drugs against clinical isolates of Klebsiella pneumoniae, Escherichia coli, indole-positive and -negative Proteus species, Providencia species, and Neisseria gonorrhoeae. Moreover, cefixime was active against strains of K. pneumoniae, E. coli, as well as Proteus mirabilis resistant to the reference agents [1]. In vivo: The therapeutic activities of cefixime in mice infected with gram-negative bacilli were found to be far superior to the activities of cephalexin, cefaclor, and amoxicillin, but they were inferior to the activities against infection with Staphylococcus aureus [1]. Clinical trial: Previous study showed that the clinical success was observed in 94% of cefixime-treated patients. At the end of treatment, the overall eradication rate in the cefixime treatment group was 92% and ranged from 76% (cefaclor) to 98% (cefuroxime axetil) in the comparator treatment groups [2].
