摘要(Abstract):

该文采用在线浊度传感器技术,对中药颗粒剂溶化过程中溶液的浑浊程度进行量化表征。对探头测量位置和磁力搅拌的转速进行优化,结果搅拌转速选取400 r·min~(-1),探头位置在烧杯直径的1/4处时,测量结果准确可靠。收集105批市售中成药颗粒剂,按照《中国药典》要求进行溶化性检查,结果在5 min时间点,有57批颗粒完全溶化,对应浊度值在0~70 FTU;32批颗粒剂表现为轻微浑浊,对应浊度值在70~350 FTU;14批颗粒剂溶液浑浊,对应浊度值在350~2 000 FTU;2批颗粒剂溶液重度浑浊,对应浊度值>2 000 FTU。上述颗粒剂测试结果中,符合药典溶化性要求的批次数占比为84.76%,部分品种的溶化性仍有待改进。通过浊度传感器记录浊度值随时间变化的曲线(溶化行为曲线),按照溶化过程中崩解和溶解的重要程度,即崩解>溶解、崩解≈溶解、崩解<溶解,可将颗粒剂的溶化行为分为3类,通过颗粒剂溶化过程中机制的解析,为产品质量和工艺改进提供依据。
In this paper, the inline turbidity sensor technology was used to quantify the turbidity of the solution during the dissolution of Chinese medicine granules. The probe measurement position and the magnetic stirring speed were optimized. As a result, the stirring speed was 400 r·min~(-1), and the probe position was at 1/4 of the diameter of the beaker. The measurement results were accurate and reliable. Totally 105 batches of commercially available Chinese medicine granules were collected and dissolved according to the requirements of the Chinese Pharmacopoeia. At the time point of 5 min, 57 batches of granules were completely dissolved, and the corresponding turbidity values ranged between 0-70 FTU; 32 batches of granules showed a slight turbidity, and the corresponding turbidity values ranged between 70-350 FTU; 14 batches of granule solution were turbid, and the corresponding turbidity values ranged between 350-2 000 FTU; two batches of granule solution were heavily turbid, and the corresponding turbidity values were >2 000 FTU. Among the above results, the number of batches in line with the pharmacopoeia dissolution requirement was 84.76%, and the dissolution of some granules still needed to be improved. The turbidity sensor recorded the change curve of turbidity value over time(solubility behavior curve). The degree of important of disintegration and dissolution during the dissolution process showed disintegration > dissolution, disintegration≈dissolution, disintegration < dissolution. The dissolution behavior of the granules can be classified into three categories. The analysis of the mechanism in the process of granule solubility provides a basis for product process improvement.
