Trough serum concentration
WebThe two levels separated in time are used to calculate the k elim and the V d. If standard assumptions hold true, these values can be used to calculate the trough concentration at steady state for any dosing regimen. These assumptions are: The timing of the dose administration and the levels are reasonably accurate. WebOriginally, ototoxicity was believed to result from transiently high peak serum concentrations, resulting in a high concentration of drug in the inner ear. Recent studies in animal models have...

WebFigure 4 Relationship between serum trough concentration and ratio of loading dose for 3 days to Cl cr in 113 patients. Notes: There was a significant correlation between serum trough concentration and ratio of loading dose for 3 days to Cl cr (R=0.59, P<0.001). Abbreviations: C min, minimum concentration; Cl cr, creatinine clearance. WebObjectives: Adult guidelines suggest an area under the curve/minimum inhibitory concentration (AUC/MIC) > 400 corresponds to a vancomycin trough serum concentration of 15 to 20 mg/L for methicillin-resistant Staphylococcus aureus infections, but obtaining these troughs in children are difficult.
