描述 | Cefuroxime sodium is an orally active second-generation cephalosporin antibiotic with increased stability to β-lactamase. It is against Staphylococcus aureus methicillin susceptible; S. aureus, methicillin resistant; Streptococcus pyogenes; S. pneumonia; S. viridans; S. faecalis and Clostridium spp with MIC values of 0.25 μg/ml, 5.9 μg/ml, 0.125 μg/ml, 0.125 μg/ml, 0.125 μg/ml, >125.0 μg/ml, and 1.2 μg/ml, respectively. It is highly active against Neisseria gonorrhoeae, Neisseria meningitidis, and also Haemophilus influenzae, including ampicillin-resistant strains. Cefuroxime is rapidly bactericidal and induces the formation and subsequent lysis of filamentous forms over a small concentration range[2]. Rabbits (weighing 2.0 to 2.5 kg) are challenged intravenously with S. aureus strain 630 (a penicillinase-producing strain), the median effective dose of Cefuroxime sodium is 3 mg/kg as a result of the protection test[3]. After both i.v. and intramuscular injections of cefuroxime sodium, the concentrations of cefuroxime in urine were much higher than that in serum. The systemic bioavailability of cefuroxime sodium in goats after intramuscular injections of 20 and 40 mg/kg body weight was 88.4 percent and 103.5 percent, respectively. In vitro protein binding of cefuroxime sodium in goat's serum was low, ranging from 13.3 percent to 21.6 percent with an average of 17.0 percent[4]. |

溶解方案 |
DMSO: 105 mg/mL(235.23 mM),注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO H2O: 50 mg/mL(112.02 mM),配合低频超声助溶 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
