We evaluated the activities of ceftriaxone (15 mg/kg), netilmicin (6 mg/kg), and their combination given intramuscularly once daily for 4 days for the treatment of experimental Escherichia coli endocarditis in rabbits. In vitro, a greater rate of killing and an increased trough serum bactericidal titer (P less than 0.01) were achieved with the combination. In vivo, the combination had a greater bactericidal effect (P less than 0.01) and resulted in a greater number of sterile vegetations (P less than 0.05) than single-drug therapy. Thus, in vivo, an increased effect can be obtained despite a single daily dose of a long-acting cephalosporin and an aminoglycoside.
我们评估了头孢曲松(15毫克/千克)、奈替米星(6毫克/千克)及其联合用药(每日一次肌肉注射,共4天)治疗兔实验性大肠杆菌心内膜炎的效果。在体外,联合用药实现了更高的杀菌率和更高的谷浓度血清杀菌效价(P<0.01)。在体内,联合用药比单一药物治疗具有更强的杀菌效果(P<0.01),并导致无菌赘生物数量更多(P<0.05)。因此,在体内,尽管每日仅使用一剂长效头孢菌素和一种氨基糖苷类药物,仍可获得增强的疗效。
