[Preparation and prescription of enteric coated pellets of Panax notoginseng saponins pellets].
OBJECTIVE
To prepare enteric coated pellets containing panax notoginseng saponins.


METHODS
Panax notoginseng saponins loaded pellets were prepared by Extrusion-Spheronization method, and coated by Eudragit L30D-55 using Glatt fluid bed with the bottom spray process, central composite design was used to optimize the coating prescription.


RESULTS
The drug release of enteric coated pellets of panax notoginseng saponins pellets would be lower than 5% in 2 h in simulated gastric fluid, but reach above 85% in 3 h in simulated human gastroenteric environment.


CONCLUSIONS
The enteric coated pellets of panax notoginseng saponins have good acid residence to avoid panax notoginseng saponins from degrading in gastric acid.
