Subacute toxicity of colistin methanesulfonate in rats: comparison of various intravenous dosage regimens

Antimicrob Agents Chemother. 2008 Mar;52(3):1159-61. doi: 10.1128/AAC.01101-07. Epub 2008 Jan 7.

Abstract

The relative nephro- and neurotoxicity of colistin methanesulfonate (CMS) was investigated with rats during 7 days of intravenous administration in regimens mimicking twice- and once-daily dosing of a clinically relevant dose for humans. Histological examination revealed more-severe renal lesions with the regimen corresponding to once-daily dosing, indicating that the potential for renal toxicity may be greater with extended-interval dosing.
