  In the text S.Piekarski, M.Rewekant,(arXiv:1208.3847)it has been mentioned
that some information on bioavailability and bioequivalence of drugs can be
obtained from simulations based on the conservation laws. Here we shortly
discuss that possibility starting from the fundamental pharmacokinetic
parameter called AUC (Area Under the Curve). The curve is is the profile shape
of plasma drug concentration in time intervals after drug administration into
organism. Our aim here is to give some information on the subject for the
reader with no experience in pharmacokinetics.
