A theoretical framework for estimation of AUCs in complete and incomplete sampling designs. [PDF]
, 2009 Nonclinical in vivo animal studies have to be completed before starting clinical studies of the pharmacokinetic behavior of a drug in humans. The drug exposure in animal studies is often measured by the area under the concentration versus time curve (AUC)
