Area under the curve (AUC):

Area under the curve is a measure of drug concentration and belongs to the field of pharmacokinetics. Area under the curve, from zero to infinity, is the exposure of the medication or the drug over a period of time. It is the measure of drug concentration in the blood plasma in a time period. The AUC reflects exposure of the drug on the body after administration. It is also dependent on the rate of elimination from the body. Also, the higher the rate of clearance of the drug from the body, the lesser the AUC. This value gives precious information on the efficacy of a drug.
