The mutant prevention concentrations (MPCs) of levofloxacin alone and in combination with ceftazidime, colistin (polymyxin E), meropenem, piperacillin-tazobactam, and tobramycin were established against Pseudomonas aeruginosa. Antibiotic combinations using levofloxacin with any antibiotic with individual activity against P. aeruginosa resulted in synergistic lowering (an at-least-fourfold reduction) of the isolate's MPC.
测定了左氧氟沙星单独使用以及与头孢他啶、黏菌素(多黏菌素E)、美罗培南、哌拉西林-他唑巴坦和妥布霉素联合使用时对铜绿假单胞菌的突变预防浓度(MPC)。左氧氟沙星与任何对铜绿假单胞菌具有单独活性的抗生素联合使用,均导致分离株的MPC协同降低(至少降低四倍)。
