WebApr 12, 2024 · Bioavailability is calculated by comparing plasma levels of a drug given via a particular route of administration (for example, orally) with plasma drug levels achieved by IV injection. This is where the AUC comes into play (the area under the curve calculated by plotting plasma concentrations of the drug versus time). The AUC equals the total …
In pharmacokinetics, bioavailability generally refers to the fraction of drug that is absorbed systemically and is thus available to produce a biological effect. This is often measured by quantifying the "AUC". In order to determine the respective AUCs, the serum concentration vs. time plots are typically gathered using C-14 labeled drugs and AMS (accelerated mass spectrometry).
