没有含量测定的中成药做重量差异有一定的质量控制意义。按丸服用的丸剂,用平均丸重比较来判断丸重差异,不能有效地控制服用量;用标示丸重或标示总量比较来判断丸重差异可确保服用剂量的准确性。故《中国药典》1995版丸剂检查项规定有第一法和第二法。部颁标准收载的浓缩丸,服用均按丸服用,但大多数无标示量(无规格),在执行标准时,给我们的实际检验工作带来一定的偏差,以至对药典规定的重量差异标准无所适从。1 问题1-1 1997年佛慈药厂送兰州市药检所报批的三个浓缩丸产品:香砂养胃丸,六味地黄丸,逍遥丸(均为三… 相似文献

In the transition of the pharmaceutical industry from batchwise to continuous drug product manufacturing, the drying process has proven challenging to control and understand. In a semicontinuous fluid bed dryer, part of the ConsiGma? wet granulation line, the aforementioned production methods converge. Previous research has shown that the evolution of moisture content of the material in this system shows strong variation in function of the granule size, making the accurate prediction of this pharmaceutical critical quality attribute a complex case. In this work, the evolution of moisture content of the material in the system is modeled by a bottom-up approach. A single granule drying kinetics model is used to predict the moisture content evolution of a batch of material of a heterogeneous particle size, where it is the first time that the single granule drying mechanism is validated for different granule sizes. The batch approach was validated when the continuous material inflow rate and filling time of the dryer cell are constant. The original single granule drying kinetics model has been extended to capture the granules’ equilibrium moisture content. Finally, the influence of drying air temperature is captured well with a droplet energy balance for the granules. 相似文献

地黄叶总苷浸膏真空带式干燥工艺优化研究 总被引:1,自引:0,他引:1
目的研究地黄叶总苷浸膏真空带式干燥的最佳工艺,并与其他干燥方法进行比较。方法以干燥产品含水率及有效成分保留率为评价指标,对影响干燥效果的因素进行考察。在单因素实验结果的基础上,采用L9(34)正交试验法,结合方差分析与多指标综合评分结果,获得地黄叶总苷浸膏真空带式干燥的最佳工艺参数,并将其干燥效果与真空烘箱干燥、微波真空干燥进行比较。结果地黄叶总苷浸膏真空带式干燥的最佳工艺条件为传送带速度4cm·min-1,浸膏进料速度25mL·min-1,加热系统温度75℃,75℃,该条件下地黄叶总苷浸膏干燥产物含水率为2.54%,毛蕊花糖苷保留率和地黄叶总苷保留率分别为94.54%和90.49%。结论优选得到的地黄叶总苷浸膏真空带式干燥工艺稳定可靠。与真空烘箱干燥和微波真空干燥相比,真空带式干燥具有干燥产品含水率低、有效成分保留率高、干燥时间短和可连续生产等优点,为中药浸膏的真空带式干燥工艺设计和过程控制提供了参考。 相似文献

Purpose Water content and granule size are recognized as critical process and product quality parameters during drying. The purpose
of this study was to enlighten the granule behavior during fluid bed drying by monitoring the major events i.e. changes in
water content and granule size.
Methods NIR spectra collected during drying and water content of sampled granules were correlated by principal component analysis
(PCA) and partial least squares regression (PLSR). NIR spectra of dried granules were correlated to median granule size in
a second PCA and PLSR.
Results The NIR water model discriminates between various stages in fluid-bed drying. The water content can be continuously predicted
with errors comparable to the reference method. The four PLS factors of the granule size model are related to primary particle
size of lactose, median granule size exceeding primary particle size and amorphous content of granules. The small prediction
errors enable size discrimination between fines and granules.
Conclusion For product quality reasons, discrimination between drying stages and end-point monitoring is highly important. Together with
the possibilities to determine median granule size and to distinguish fines this approach provides a tool to design an optimal
drying process. 相似文献
