摘要
目的:根据药动/药效(PK/PD)理论应用蒙特卡罗模拟进行6种抗菌药物对铜绿假单胞菌给药方案的评价。方法:将左氧氟沙星、环丙沙星、头孢吡肟、头孢他啶、哌拉西林/他唑巴坦和亚胺培南/西司他丁各给药方案对铜绿假单胞菌进行5 000次蒙特卡罗模拟,通过获得的累积反应分数(CFR)对给药方案的治疗效果进行比较。结果:左氧氟沙星(0.5 g qd)的CFR为27.55%;环丙沙星(0.4 g qd)的CFR分别为79.33%;头孢吡肟4种给药方案(1 g bid,1 g tid,2 g bid和2 g tid)的CFR分别为56.14%,70.51%,69.18%和82.77%;头孢他啶4种给药方案(1 g bid,1 g tid,2 g bid和2 g tid)的CFR分别为18.02%,40.71%,31.15%和71.17%;哌拉西林/他唑巴坦2种给药方案(4.5 g tid和4.5 g q6h)的CFR分别为33.66%和56.31%;亚胺培南/西司他丁2种给药方案(1 g tid和1 g q6h)的CFR分别为为67.75%和73.58%。结论:6种抗菌药物临床常规单药治疗耐药情况严重,因此当铜绿假单胞菌感染时需考虑联合用药。
Objective: To estimate the dosage regimens of six kinds of antimicrobial agents for pseudomonas aeruginosa utilizing Monte Carlo simulation (MCS) based on PK/PD. Methods: A 5 000-subject Monte Carlo simulation was conducted to determine the cumulative fraction of response (CFR) for levofloxacin, ciprofloxacin, cefepime, ceftazidime, piperacillin/tazobactam and imipenem-cilastatin against Pseudomonas aeruginosa. Results: The CFRs were 27.55% for levofloxacin (0.5 g qd); 79.33% for ciprofloxacin (0.4 g qd) ; 56.14% , 70.51%, 69.18% and 82.77% for four dosage regimens of cefepime (1 g bid, 1 g tid, 2 g bid and 2 g tid) ; 18.02% , 40.71% , 31.15% and 71.17% for four dosage regimens of ceftazidime (1 g bid, 1 g tid, 2 g bid and 2 g tid) ; 33.66% and 56.31% for piperacillin/tazobactam (4.5 g tid and 4.5 g q6h) ; 67.75% and 73.58% for imipenem-cilastatin (1 g tid and 1 g q6h). Conclusion: The dosage regimen of six kinds of antibacterial drugs for pseudomonas aeruginosa has not been optimized, so the drug monas aerueinosa infection. combination should be considered for the treatment of pseudo-monas aeruginosa infection.
