R calculate auc from c trough
WebFrom here, the true trough (C min) can be calculated using the C max from the following formula: C min = C max * e -k (Tau-tinf) Where Tau is the dosing interval and tinf is the infusion time in hours. Now, the AUC can be calculated. Commonly, the trapezoidal rule is used to calculate the AUC by hand.

WebC trough and AUC 24 using either ref or EqA were correlated more closely (r 2 = 0.94) than with EqB (r 2 = 0.86). Assuming a vancomycin MIC of 1 mg/L, an AUC 24 ≥400 mg⋅h/L was targeted. Regardless of the method used, AUC 24 ≥400 mg⋅h/L was never seen with C trough <8 mg/L but was always seen with C trough >10 mg/L. dwg fast view proWebCalculation of confidence intervals for an area under the concentration versus time curve (AUC) or for the difference between two AUCs assessed in complete and incomplete data designs. ... ## example from Gibaldi and Perrier (1982, page 436) for an individual AUC time <- c (0, 0.165, ... dwg fastview iosWebApr 10, 2024 · Adding GF improves the performance by 2.019% in terms of AUC and 3.261% in terms of accuracy.
