Bioavailability determinations according to the height plasma concentration is often deceptive since drug elimination commences the moment the drug enters the bloodstream.
Bioavailability will likely be assessed by identifying the region underneath the plasma concentration–time curve (AUC—see figure Representative plasma concentration–time romantic relationship after just one ora...). Probably the most responsible measure of a drug’s bioavailability is AUC.
A perfect environment for these sorts of scientific studies is in the context of huge multi-institution scientific trials, in which in depth reaction and toxicity details (phenotype info) are kept and might be linked to genetic or genomic information extracted from sufferers enrolled to the trial.
