To develop a meropenem population pharmacokinetic model in critically ill patients with particular focus on optimizing dosing regimens based on renal function. Population pharmacokinetic analysis was performed with creatinine clearance (CrCl) and adjusted body weight to predict parameter estimates. Initial modeling was performed on 21 patients (55 samples).(More)
A population pharmacokinetic model of cefepime was constructed from data from adult critical care patients with ventilator-associated pneumonia (VAP). A total of 32 patients treated with high-dose cefepime, 2 g every 8 h (3-h infusion) or a renal function-adjusted equivalent dose, were randomized into two groups--26 for the initial model and 6 for model(More)
Gram-positive organisms are continually a major cause of infection. These organisms are ever-evolving and exhibit resistance to nearly all available agents. Historically, vancomycin was crowned the drug of choice for many of these organisms including methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, and(More)
GSK2140944 is a novel bacterial type II topoisomerase inhibitor with in vitro activity against key causative respiratory pathogens, including methicillin-resistant Staphylococcus aureus (MRSA). We described the pharmacodynamics of GSK2140944 against MRSA in the neutropenic murine lung infection model. MICs of GSK2140944 were determined by broth(More)
Ceftaroline exhibits bactericidal activity against Gram-positive pathogens, including methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) Staphylococcus aureus, as well as common Gram-negative pathogens. This study evaluated the efficacy of human simulated exposures of ceftaroline against S. aureus in both the neutropenic and immunocompetent(More)
Multidrug resistance in Gram-negative bacteria has become so threatening to human health that new antibacterial platforms are desperately needed to combat these deadly infections. The concept of siderophore conjugation, which facilitates compound uptake across the outer membrane by hijacking bacterial iron acquisition systems, has received significant(More)
OBJECTIVES When evaluating the pharmacodynamics of antimicrobials, assumptions are often made relative to their pharmacokinetics. One example of this is applying tissue penetration results of uninfected hosts to those displaying a targeted illness. As tigecycline evolves into a potential treatment option for pneumonia, we determined whether the presence of(More)
Tigecycline (TGC) is an extended-spectrum antibiotic with activity against Staphylococcus aureus, including methicillin (meticillin)-resistant S. aureus strains, which are well-recognized pathogens in nosocomial pneumonia. The objective of this study was to characterize the exposure-response relationship for TGC against S. aureus in an immunocompromised(More)
Tigecycline is a glycylcycline with activity against Enterobacteriaceae, including multidrug-resistant isolates of Klebsiella pneumoniae and Escherichia coli producing extended-spectrum beta-lactamase (ESBL) and carbapenemases. Herein, we used an in vivo murine thigh model to characterize the pharmacodynamic profile of tigecycline against genotypically and(More)
The antibacterial efficacies of tedizolid phosphate (TZD), linezolid, and vancomycin regimens simulating human exposures at the infection site against methicillin-resistant Staphylococcus aureus (MRSA) were compared in an in vivo mouse pneumonia model. Immunocompetent BALB/c mice were orally inoculated with one of three strains of MRSA and subsequently(More)
