Previous studies using the chinchilla animal model demonstrated that the third generation cephalosporin cefixime (Suprax) with split dosing was as effective as ampicillin in sterilizing the middle ear cleft when infected with S. pneumoniae. In this investigator-blinded, randomized trial, a single daily dose of cefixime (8 mg/kg per day) performed as well as split dosing of cefixime (8 mg/kg every 8 h) and ampicillin (150 mg/kg every 8 h) in the time to sterilization of the middle ear cleft. No statistically significant differences were noted between groups in otoscopy or tympanometry. All antibiotic regimens performed better than saline control (P < 0.0001) with regard to time to sterilization of the middle ear cleft. The results of this study support the daily administration of cefixime as an effective agent for the treatment of otitis media due to its extended half-life and broad antibiotic spectrum.
以往使用龙猫动物模型的研究表明,第三代头孢菌素头孢克肟(世福素)分剂量给药在对感染肺炎链球菌的中耳裂进行杀菌时与氨苄西林效果相当。在这项研究者设盲的随机试验中,单剂量每日一次的头孢克肟(8毫克/千克/天)在中耳裂杀菌时间方面与分剂量的头孢克肟(每8小时8毫克/千克)和氨苄西林(每8小时150毫克/千克)表现相同。在耳镜检查或鼓室导抗图方面,各组之间未发现统计学上的显著差异。就中耳裂杀菌时间而言,所有抗生素治疗方案均比生理盐水对照效果更好(P<0.0001)。这项研究的结果支持每日使用头孢克肟,因其半衰期长且抗菌谱广,是治疗中耳炎的有效药物。
