ABSTRACT
AIM:To establish a network pharmacoki- netic model for studying multiple drug components and analyzing their parameters.METHODS:A model has been set up based on the compartment and linear kinetic theories,and the solutions have been obtained by Laplace transform method.The relations between the whole comp- artment model and network model for multiple component have been comparatively studied and their kinetic parame- ters have also been estimated and analyzed.RESULTS: The multiple component network pharmacokinetics follow a first order linear mammillary model.C_i is a polynomial of power index number e,which is similar to the whole compartment model.Various parameters(transit constant) were calculated by the expression of matrix consisting of?_i and the compartment parameters.Its kinetic parameters can be obtained on the basis of the whole compartment model.CONCLUSION:The multiple component net- work pharmacokinetic parameters can be obtained and an- alyzed similarly as the whole compartment model.
