| Abstract: | Objective:To prepare nicardipine hydrochloride sustained-release pellets,and to research factors affecting the release rate in vitro. Methods:The rolling coacervation method was used to prepare nicardipine hydrochloride sustained-release pellets, and ultraviolet spectrometry was used to assess the release of nicardipine hydrochloride in vitro.Results:The release rate of nicardipine hydrochloride decreased considerably with the growth of the thickness of membrane and Mw of PLA.Conclusion:PLA can be used to prepare oral nicardipine hydrochloride sustained-release. |
