Effects of extracorporeal membrane oxygenation on pharmacokinetics and pharmacodynamics of daptomycin in critically ill patients / 中国临床药理学与治疗学

ABSTRACT

AIM: To investigate the effect of extracorporeal membrane oxygenation (ECMO) on the pharmacokinetics/pharmacodynamics (PK/PD) of daptomycin in critically ill patients. METHODS: Twenty four patients with severe infection in our hospital were randomly selected and divided into ECMO group and non ECMO group. They were intravenously injected with daptomycin 500 mg qd. After the drug reached the stability statement, venous blood was collected at different time points before and after the infusion. The plasma drug concentration was measured and the pharmacokinetic parameters were calculated. The probability target acquisition (PTA) and the cumulative fraction response (CFR) were calculated by Monte Carlo simulation. RESULTS: After dosing, the main pharmacokinetic parameters in ECMO and non-ECMO group were calculated and listed as follows: C
