Evaluation of Vancomycin Pharmacokinetics with Two Different Regimens in Patients with Augmented Renal Clearance
Design
Randomized clinical trial with parallel groups on 56 patients. Block randomization method will be used trough online website.
Settings and conduct
This study will be conducted in the Loghman Hakim hospital, Tehran. Patients with augmented renal clearance will be allocated into two groups randomly and vancomycin will be administered every 8 hours or every 12 hours. Finally, blood samples will be taken to measure peak and trough levels of vancomycin.
Participants/Inclusion and exclusion criteria
In this study, patients who needs vancomycin empirically or according to the culture will be included. These patients are over 18 years old and have augmented renal clearance (ARC) score between 7 and 10 or augmented renal clearance in trauma intensive care (ARCTIC) score over than 6. Patients with creatinine level lower than 1.5 mg/dL will be excluded. After initiation of intervention, the clearance of creatinine will be measured with collection of eight hours urine and patients with clearance of creatinine lower than 130 mL/minute will be excluded.
Intervention groups
In the first group, patients will be received intravenous vancomycin manufactured by Exir company at dose of 15 to 20 mg/kg every 12 hours. In the second group, patients will be received intravenous vancomycin manufactured by Exir pharmaceutical company at dose of 15 to 20 mg/kg every 8 hours. The infusion rate of vancomycin is 1000 mg per hour. One hour after ending the infusion of forth dose, blood sample will be taken to measure the peak level of vancomycin. Then, 30 minutes before administration of fifth dose blood sample will be taken to measure the trough level of vancomycin.
Main outcome variables
Ratio of patients who achieves Area under the curve (AUC)/Minimum inhibitory concentration (MIC) over 400.
