RT Journal Article SR Electronic A1 Vinall, Phil T1 Standard Dosage Regimens of Broad-Spectrum β-Lactams are Inadequate to Treat “Difficult-to-Treat” Pathogens in Obese Noncritically Ill Patients JF MD Conference Express YR 2012 FD SAGE Publications VO 12 IS 14 SP 28 OP 28 DO 10.1177/155989771214013 UL http://mdc.sagepub.com/content/12/14/28.1.abstract AB Results of a large case series of broad spectrum β-lactam agents in obese noncritically ill patients with infection treated using standard dose regimens showed insufficient measured serum concentrations to treat difficult-to-treat pathogens. This article presents a poster [Hites et al. ICAAC 2012 a-637] that suggested altered pharmacokinetics in obese patients may be responsible.
