Abstract:
Objective To prepare Shichangpu Double Layer Tablets. Methods The release of the sustained-release layer (SRL) was used as the response parameters and uniform design with alterable levels was used to optimize the recipe of SRL of Shichangpu Double Layper Tablets. Fast-release layer (FRL) was made from water extraction by ultra-filtration. Results The dissolution kinetics of SRL could follow zero-order equation and FRL showed good prosperities for fast release in 10 min. Conclusion The in vitro release of SRL of Shichangpu Double Layer Tablets testifies the significant sustained release action and FRL disintigrates rapidly. The preparation technology of Shichangpu Double Layer Tablet is reliable and simple.
