【摘要】:目的研究枸櫞酸莫沙必利(MC)及其片劑在體內(nèi)外實驗?zāi)P偷哪c吸收情況,并探討其吸收機制。方法建立Caco-2單層膜和大鼠在體單向腸灌流模型,采用酚紅法對灌流液體積進行校正,建立高效液相色譜法同時測定酚紅和枸櫞酸莫沙必利的濃度,計算藥物的P_(app)和P_(eff)值。結(jié)果枸櫞酸莫沙必利在大鼠各腸段都有吸收,在小腸上端吸收量最多。MC自研與原研片劑在Caco-2細胞和大鼠單向腸灌流實驗中都具有高滲透性。結(jié)論自研片和原研產(chǎn)品在Caco-2細胞和大鼠單向腸灌流模型中的吸收具有較高一致性。
[Abstract]:Objective to study the intestinal absorption of mosapride citrate (MC) and its tablets in vitro and in vivo. Methods the Caco-2 monolayer membrane and rat unilateral intestinal perfusion model were established. The volume of perfusion fluid was corrected by phenolic red method. The concentration of phenolic red and mosapride citrate were determined by HPLC. P _ (app) and P _ (eff) were calculated. Results mosapride citrate was absorbed in all intestinal segments of rats, and the amount of absorption was the highest at the upper end of small intestine. Both MC self-made and original tablets were highly permeable in Caco-2 cells and unidirectional intestinal perfusion experiments in rats. Conclusion the absorption of self-made tablets and original products in Caco-2 cells and in unidirectional intestinal perfusion model of rats has high consistency.
