Abstract

Doripenem is a broad-spectrum parenteral carbapenem with enhanced activity against Pseudomonas aeruginosa and Enterobacteriaceae Current dosing regimens recommend the administration of 0.25 to 0.5 g once daily in patients undergoing intermittent renal replacement therapy. As patients are usually dialyzed thrice weekly, we aimed to investigate a 1-g posthemodialysis regimen, thus reducing treatment costs and enhancing patient compliance. A second objective of this trial was to describe the pharmacokinetics of intradialytic doripenem. Ten oliguric or anuric patients in need of intermittent renal replacement therapy were included in this trial. All patients suffered from a septic episode. The mean hemofilter clearance was 123.46 ± 42.03 ml/min, and the total body clearance between hemodialysis sessions was 16.79 ± 6.02 ml/min. The average prehemodialysis trough concentration was 2.4 ± 1.3 mg/liter, while the EUCAST resistance breakpoint for Enterobacteriaceae is set at 2 mg/liter. The interpatient variability was considerably higher than the intrapatient variability. Apart from one patient who suffered an allergic reaction, doripenem was tolerated well by all patients. Our data indicate that posthemodialysis administration of 1 g of doripenem results in sufficient plasma levels in anuric but not oliguric patients during the entire dosing interval. (This trial was registered with EudraCT under registration no. 2009-018010-18 and at ClinicalTrials.gov under registration no. NCT02018939.).
