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. WebInter-dose AUC (ie, most generally AUC 0–12 h) is more informative than C 0 because it correlates better with rejection in patients with kidney transplants [16–18]. However, AUC 0–12 h estimation based on a complete pharmacokinetic profile requires multiple blood samples over a 12-h period, which is uncomfortable for the patient and costly.
