CVVH clearance contributes a major fraction of the total levetiracetam clearance (36-73%) in neurocritically ill patients. The average bias and precision of the estimated vs. observed total clearance value was ~ 10.6% and 21.5%. Major dose determinants were identified to be SC and effluent flow rate. Patients with higher ultrafiltrate rates will have increased drug clearance and, therefore, will require higher doses in order to match exposures seen in patients with normal renal function. © 2020 The Authors.

Herein, the hard template method was used for the preparation of N-doped mesoporous carbon sorbent. The prepared sorbent was characterized using the Brunauer-Emmett-Teller, transmission electron microscopy, and elemental analysis. Parameters affecting the extraction of the target metabolite were investigated using the Box-Behnken design method. Considering optimum parameters, the plotted calibration curve for 1-OHP was linearly correlated with the concentration span of 0.1-50 μg L-1 for urine media. The accuracy of the optimized procedure was examined through the relative recovery tests on the fortified urine specimens. The relative recoveries fell between 95 to 101%. The method detection limit of the proposed procedure was also calculated to be 0.03 μg L-1 . This article is protected by copyright. All rights reserved. This article is protected by copyright.
