我们把传统的快速静脉注射药物动力学模型改进为脉冲微分方程模型,运用脉冲微分方程理论研究一个两室的多次快速静脉注射脉冲模型的稳态血药浓度(坪浓度),峰浓度,最小有效血药浓度和平均血药浓度,用药间隔周期等等,从而便于设计最佳用药方案.该文所得结论对指导临床用药具有积极意义并丰富了现有的药物动力学的研究成果. We improved the traditional rapid intravenous injection pharmacokinetic model as a model of impulsive differential equations and used the theory of impulsive differential equations to study steady-state plasma concentrations (peak concentrations), peak densities, and peak concentrations in a two-compartment, rapid intravenous injection pulse model Effective blood concentration and mean plasma concentration, interval of medication and so on, so as to facilitate the design of the optimal drug regimen.The conclusions drawn in this paper are of positive significance to guide the clinical medication and enrich the existing research results of pharmacokinetics.
