    Notes: Abstract Based on a stochastic pharmacokinetical model (which mirrors topological properties of the circulatory system) it is shown by reinterpreting results of Wise (1974) that if the transit times of circulating drug molecules have a generalized inverse Gaussian distribution the corresponding residence times are gamma distributed. The condition that the probability of elimination of a drug molecule in a single circulatory passage is sufficiently small appears to be valid for most drugs. Thus theoretical evidence is given for fitting blood concentration-time curves following bolus injection of a single dose by power functions of time.

    Notes: Abstract We first introduce some main problems in pharmacokinetics and then we propose methods for their resolution. Of course, identification problem is considered. A numerical efficient method is given. It brings back to the resolution of a succession of linear algebraic systems. In the case of non unicity we suggest an approach based on the adjunction of a criterion to minimize. The last part studies the optimal injection of a drug associated to an optimization criterion. An explicit solution can be found for a n-compartments linear system.
