Antibiotic dosing in critically ill patients with continuous renal re-placement therapy (CRRT) is still challenging. Pharmacokinetic changesin critically ill patients such as increased volume of distribution and de-creased protein binding affinity affect hydrophilic drug dosing regimens. Consequently, we might prescribe inadequate doses of antimicro-bial agents in patients with CRRT  which can affect the morbidityand mortality associated with sepsis . Requirement of loading dose and higher maintenance doses for this group of patients has been sug-gested to achieve pharmacokinetic and pharmacodynamic targets .Continuous renal replacement therapy has been utilizing to effec-tively remove fluid and waste products in this group of patients due tohemodynamic instability . Doripenem is a water-soluble carbapenemantibiotic and commonly used for Gram negative infection in intensivecare unit (ICU) . It can be removed by CRRT due to small molecular
weight (438.52 Da) and low volume of distribution (16.8 L) .
The recommended dosing regimens from clinical resources are mostly from the pharmacokinetic studies in Western patients and there were a few studies conducted in Asian population [7-12]. No sug-gested doripenem dosing regimens for CRRT patients based on Asianpharmacokinetic parameters exists. This study aimed to define the opti-mal doripenem dosing regimens using pharmacokinetic parameters from Asian population and body weights of Asian critically ill patients
