RT Journal Article SR Electronic T1 Vancomycin: A 50-something-yearold antibiotic we still don’t understand JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 465 OP 471 DO 10.3949/ccjm.78a.10168 VO 78 IS 7 A1 Amy Schilling A1 Elizabeth Neuner A1 Susan J. Rehm YR 2011 UL http://www.ccjm.org/content/78/7/465.abstract AB Because a significant proportion of Staphylococcus aureus strains as well as most coagulase-negative staphylococci are resistant to penicillin and semisynthetic beta-lactam drugs, the need for vancomycin and related antibiotics has never been greater. Effective use of vancomycin requires knowledge of dosing parameters and selection of target trough levels appropriate to the specific infection and to the pathogen being treated. For clinicians, it is vital to remain up-to-date with evolving definitions for vancomycin susceptibility, with new interpretations of efficacy, and with information on toxicity.
