The in vitro activities of linezolid were determined alone and in combination with vancomycin, ciprofloxacin, gentamicin, fusidic acid, or rifampin against five methicillin-susceptible Staphylococcus aureus (MSSA) and five methicillin-resistant S. aureus (MRSA) strains. Similar responses were obtained against MSSA and MRSA. When combined with fusidic acid, gentamicin, or rifampin, linezolid prevented selection of resistant mutants but showed no synergy. When linezolid was combined with vancomycin and ciprofloxacin, a slight antagonism was observed. While the combination with linezolid may reduce the emergence of mutants resistant to the associated drugs, the absence of synergy, especially in the case of vancomycin and ciprofloxacin, does not argue in favor of such combinations.
单独测定了利奈唑胺以及利奈唑胺与万古霉素、环丙沙星、庆大霉素、夫西地酸或利福平联合使用时对5株甲氧西林敏感金黄色葡萄球菌(MSSA)和5株甲氧西林耐药金黄色葡萄球菌(MRSA)菌株的体外活性。对MSSA和MRSA获得了相似的反应。当与夫西地酸、庆大霉素或利福平联合使用时,利奈唑胺可防止耐药突变体的产生,但未显示协同作用。当利奈唑胺与万古霉素和环丙沙星联合使用时,观察到轻微拮抗作用。虽然与利奈唑胺联合使用可能会减少对相关药物耐药的突变体的出现,但缺乏协同作用,尤其是在万古霉素和环丙沙星的情况下,并不支持这种联合使用。
