Einheit area under the curve

In der Medizin und Pharmakologie bezeichnet Area under the curve (AUC) die Fläche unter der Konzentrations-Zeit-Kurve eines Pharmakons im Blut. Sie ist die Größe, durch welche die Bioverfügbarkeit eines Pharmakons ausgedrückt wird. Die deutschsprachige Entsprechung „Fläche unter der Kurve“ hat sich in der Fachliteratur nicht durchgesetzt.
