摘要: 目的: 采用药效动力学方法评价复方丹参骨架缓释片(CDSRT)的缓释作用。方法: 以市售复方丹参片(CDT)为对照,分别给予正常大鼠CDT、CDSRT(折算生药材 2911.14 mg/kg),于给药后 0.25、0.5、0.75、1、2、4、8、12 h 制备含药血清,并将含药血清作用于心肌细胞,考察CDT和CDSRT对缺氧/复氧心肌细胞损伤的保护作用,评价CDSRT的缓释作用。结果: 与模型组比较,CDT 4、8 h 的含药血清和CDSRT 2、4、8、12 h 的含药血清对缺氧/复氧损伤心肌细胞均有促增殖作用;CDT和CDSRT的效应半衰期t1/2(ka)分别为 2.655 和 0.719 h,效应达峰时间tmax 分别为 5.213 和 2.957 h,效应消除半衰期t1/2(ke)分别为 4.953 和 10.166 h。与CDT相比,CDSRT效应半衰期和效应达峰时间短,消除速率低。结论: 复方丹参骨架缓释片效应消除半衰期长,具有一定的缓释作用。药效动力学方法可作为其缓释作用的评价方法之一。

Abstract: AIM: To evaluate the sustained-release effect on Compound Danshen Skeleton Sustained-Release Tablet (CDSRT) by pharmacodynamics method.METHODS: By reference to Compound Danshen Tablet(CDT), Sprague-Dawley rats had been administrated with CDT and CDSRT with the content of crude drugs 2911.14 mg/kg. The medicated serum of CDT and CDSRT were prepared at the time of 0.25,0.5,0.75,1,2,4,8,12 h after single oral administration. The medicated serums were added to myocardial cells respectively. The protective effects of CDT and CDSRT on hypoxia/reoxygenation and the sustained-release effect of CDSRT were evaluated.RESULTS: Compared with the H/R model group, the medicated serum of CDT 4,8 h and CDSRT 2,4,8,12 h had apparent protective effects against proliferation inhibition caused by hypoxia/reoxygenation(H/R) induced injury in myocardial cells. The present half-life t1/2(ka) of CDT and CDSRT were 2.655 h and 0.719 h. The peak times of effective action were 5.213 h and 2.957 h. And the elimination half-life t1/2(ke) were 4.953 h and 10.166 h respectively. Compared with CDT, CDSRT had a higher speed of the effect present and the peak time of effective action and a lower speed of sustained-release.CONCLUSION: CDSRT has a certain sustained-release function as t1/2(ke) longer than that of CDT. Pharmacodynamics method is a feasible method for the evaluation of CDSRT sustained-release effect.
