R calculate auc from c trough

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. Webto extrapolate to infinity. This can be calculated from the AUC(0-t) by the addition of a constant (Clast/λz), where Clast is the last observed quantifiable concentration and λz is the terminal phase rate constant. • AUC(0-tau): AUC to the end of the dosing period (for example for OD dosing, the dosing tau is 24hrs.)
