title: The two faces of pharmacokinetics.
abstract: There are two main branches of Mathematics: Calculus and Geometry; in Physics there are Constructive Theories and Principle Theories. Similarly in Pharmacokinetics we can build models with two opposite approaches, the bottom-up and the top-down point of view. In this short opinion article I will try to show, with the help of a few examples, the advantages of each one of the two approaches.
