肝苏缓释胶囊的药代动力学研究

目的：研究肝苏缓释胶囊在狗体内的药代动力学，评价肝苏缓释胶囊在体内的缓释效果。方法：以有效成分之一没食子酸为指标成分，用高效液相色谱法测定狗分别服用肝苏缓释胶囊及普通胶囊后不同时间体内没食子酸的血药浓度。结果：肝苏缓释胶囊和普通胶囊中没食子酸在体内的药代动力学过程均选择一室模型。肝苏缓释胶囊有明显的缓释作用，能在体内较长时间的保持较高的血药浓度。体外累积释放百分率与体内吸收分数有极显著的相关性，表明肝苏缓释胶囊在体内的缓释效果可以用体外累积释放百分率来进行评价。结论：肝苏缓释胶囊在体内外都有较好的缓释作用。

Study on Gansu Capsule (sustained release) in pharmacokinetics

Objective: By studying the pharmacokinetics in dogs' vivo of Gansu Capsule (sustained release), evaluate slow release effect in vivo of Gansu Capsule (sustained release). Methods: To take gallic acid as marker component, which is one of effective components, After taking Gansu Capsule (sustained release) and Gansu Capsule (common), to adopt high performance liquid chromatography to determinate the blood concentration of acid pyrogallol in dogs at different time. Results: Both Gansu capsule (sustained release) and Gansu Capsule (common) coincide one compartment model. It suggested that Gansu Capsule (sustained release) had remarkable effects of slow release and could maintain higher blood concentration in vivo longer the slow release effect of Gansu Capsule (sustained release) in vivo that could be evaluated by accumulative releasing percentage in vito. Conclusion: Gansu Capsule (sustained release) had good slow release effect in vivo and vitro.
