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.
