Colistin pharmacokinetics in intensive care unit patients on continuous venovenous haemodiafiltration: an observational study

Abstract

In spite of substantial extracorporeal clearance, total colistin clearance was reduced, compared with patients with normal renal function. Colistin adsorption by the haemofilter contributed to its extracorporeal clearance to a large extent. Studies on other patients receiving colistin methane sulphonate and undergoing CRRT are required before more appropriate dosage regimens can be recommended.
