Abstract
- ABSTRACTThe clinical development of nonsusceptibility to the lipopeptide antibiotic daptomycin remains a serious concern during therapy for infections caused by vancomycin-resistant Enterococcus faecium(VREfm). The long-acting lipoglycopeptide oritavancin exhibits potent in vitroactivity against VREfm, although its safety and efficacy for treating clinical VREfm infections have not been established. In this study, novel dosing regimens of daptomycin and oritavancin were assessed against both VREfm and daptomycin-nonsusceptible VREfm isolates in an in vitropharmacokinetic/pharmacodynamic model.
