ABSTRACT
AIM:
To explore the influencing factors in the release rate and give the application to the preparation.METHODS:
Preparing ophiopogon saponin enteric microsphere by spray drying process,the accumulative release rate of acid and buffer solution were detected by colorimetric analysis.RESULTS:
With the increase of Eudragit Ⅱ concentraction,the accumulative release rate tended to decrease.But ratio of drug and Eudragit Ⅱ,increased with the decrease in delay time on the break point.CONCLUSION:
The concentration of Eudragit and the ratio of drug and material are the rey factors in the accumulative release rate in acid and buffer solution.
