Clinical Report: Population Pharmacokinetics of Vancomycin in Adult Patients with Burns
Overview
This study developed a population pharmacokinetic (PopPK) model for vancomycin in adult burn patients, demonstrating that clearance is significantly correlated with creatinine clearance (CrCL).
Background
Burn patients are at high risk for severe infections due to compromised skin barriers and altered pharmacokinetics. Effective antibiotic dosing is crucial in this population, particularly for vancomycin, which is the first-line treatment for methicillin-resistant Staphylococcus aureus (MRSA) infections. Current dosing regimens often fail to account for the unique physiological changes in burn patients.
Data Highlights
Parameter
Value
Clearance (CL)
6.73 × (CrCL/111.67)0.708 L/h
Volume of Distribution
49.1 L
Key Findings
A one-compartment model best described vancomycin pharmacokinetics in burn patients.
Creatinine clearance was identified as a significant covariate affecting vancomycin clearance.
The developed PopPK model showed superior predictive accuracy compared to Clincalc.
Bootstrap analysis confirmed the stability of the pharmacokinetic model.
Increased clearance of vancomycin was observed in burn patients.
Clinical Implications
Clinicians should consider creatinine clearance when determining vancomycin dosing in this population.
Conclusion
The study presents a population pharmacokinetic model for vancomycin in burn patients.
