WebDec 1, 2005 · The AUC for that drug is then calculated as the area under this drug concentration curve. An AUC study contains a lot of information about PK. ... This table provides suggested trough (C min) ... 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.
