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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
