提高祛痹颗粒临界相对湿度的实验研究

Study on improving the critical relative humidity of Qubi granule

目的:提高祛痹颗粒的临界相对湿度,从而提高其抗湿性。方法:采用比较法,筛选祛痹颗粒成型的最佳处方并测定其临界相对湿度。结果:处方改良前后的祛痹颗粒的临界相对湿度分别为50%和61%,后者的临界相对湿度提高了11%。结论:处方改良后的祛痹颗粒的抗湿性有望提高。

Objective： To increase the critical relative humidity （CRH） of Qubi granule, thus to improve its humidity resistance. Methods： The best prescription of Qubi granule was optimized by comparative method, and to determine its critical relative humidity. Results： The old prescription of the Qubi granule＇s CRH was 50%.With new prescription, the Qubi granule＇ s CRH was 61%. the latter has increased by 1 1% as compared with the former. Conclusion： Considering above result, there is a hope to improve the hygroscopicity of Qubi granule.
