On applications of conservation laws in pharmacokinetics
  There has been certain criticism raised by A. Rescigno [2,8,9,12-15] against the standard formulation of pharmacokinetics. In 2011 it has been suggested that inconsistencies in pharmacokinetics should be eliminated after deriving "pharmacokinetic parameters" from conservation laws [3]. In the following text a simple system of conservation laws for extra - vascular administration of a drug is explicitly given and preliminary discussion concerning this issue is included.
