摘要
目的:建立多成分药物代谢网络动力学数学模型,并对参数进行初步分析。方法:采用线性动力学方法建模,用拉氏变换法求解,研究多成分代谢网络动力学数学模型与参数的关系,并对多成分代谢网络动力学模型中各参数的求算进行初步分析。结果:药物多成分代谢网络动力学遵循一级线性乳突模型,c_i为e的幂指数多项式形式,与总室模型相似,各参数(转运常数)由其与各室间常数构成矩阵的特征值α_i的关系方程组算得。其动力学参数可在总室模型的基础上求算。结论:多成分代谢网络动力学各参数与总室一样可求得。
AIM： To establish a network pharmacokinetic 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 compartment model and network model for multiple component have been comparatively studied and their kinetic parameters have also been estimated and analyzed. RESULTS： The multiple component network pharmacokinetics follow a first order linear mammillary model. Ci 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 αi and the compartment parameters. Its kinetic parameters can be obtained on the basis of the whole compartment model. CONCLUSION： The multiple component network pharmacokinetic parameters can be obtained and analyzed similarly as the whole compartment model.
