Objective:
To investigate the characteristics of nano-CaCO3 applicated in Xin Yue Shu Capsules.
Methods:
Studied the effect of different dosages of aerosil or nano-CaCO3 on fluidity, bulk density, moisture absorption of Xin Yue Shu capsules spray drying powder. In vitro dissolution and ferulic acid stability of Xin Yue Shu capsules was observed.
Results:
It significantly improved powder fluidity and bulk density of Xin Yue Shu spray drying powder when aerosil or nano-CaCO3 was added. But there was no significant effect on powder moisture absorption, ferulic acid in vitro dissolution and ferulic acid stability.
Conclusion:
The effect of Nano-CaCO3 on improving powder fluidity and bulk density applicated in the spray drying powder of traditional Chinese medicine deserves studying further.
