Vancomycin Area Under the Curve-Guided Dosing and Monitoring for Adult and Pediatric Patients With Suspected or Documented Serious Methicillin-Resistant Staphylococcus aureus Infections: Putting the Safety of Our Patients First.

The revised vancomycin consensus guidelines recommended area under the curve (AUC)-guided dosing/monitoring for patients with serious invasive methicillin-resistant Staphylococcus aureus (MRSA) infections as a measure to minimize vancomycin-associated acute kidney injury (VA-AKI) while maintaining similar effectiveness. Data indicate that the intensity of vancomycin exposure drives VA-AKI risk. Troughs of 15-20 mg/L will ensure an AUC ≥400 mg × hr/L but most patients will have daily AUCs >600. VA-AKI increases as a function of AUC, especially when >600. In addition to minimizing VA-AKI risk while maintaining similar efficacy, AUC-guided dosing/monitoring is a more precise way to conduct therapeutic drug monitoring for vancomycin relative to trough-only control.
