目的:研究尼索地平β环糊精(βCD)1∶1包合物的制备。方法:通过研究了βCD对尼索地平的包合作用及包合后的溶解性,并比较了尼索地平βCD包合物与原料药及PVP固体分散物片的溶出度。结果:尼索地平在包合后,其水中溶解度由包合前的7.10μg·ml-1提高到15.75μg·ml-1。结论:包合物的溶出度优于原料药,但不及固体分散物片。
Objective: To study the preparation of nisoldipine βcyclodextrin (βCD) 1: 1 inclusion complex. Methods: By studying the inclusion of β CD and nisoldipine solubility and solubility after inclusion, and the dissolution of β-CD inclusion compound of nisoldipine and API and PVP solid dispersible tablets were compared. Results: After the inclusion of nisoldipine, its solubility in water increased from 7.10μg · ml-1 before inclusion to 15.75μg · ml-1. Conclusion: The dissolution of clathrates is better than that of bulk drugs, but not as good as that of solid dispersions.
