Predictive model for hygroscopicity of contents in Guizhi Fuling Capsules / 中国中药杂志

To control the risks of powder caking and capsule shell embrittlement of Guizhi Fuling Capsules, a predictive model for hygroscopicity of contents in Guizhi Fuling Capsules was built. A total of 90 batches of samples, including raw materials, intermediate powders and capsules, were collected during the manufacturing of Guizhi Fuling Capsules. According to the production sequence, 47 batches were used as the calibration set, and the properties of raw materials and the four intermediate powders were comprehensively characterized by the physical fingerprint. Then, the partial least squares(PLS) model was developed with the content hygroscopicity as the response variable. The variable importance in projection(VIP), variance inflation factor(VIF) and regression coefficients were used to screen out potential critical material attributes(pCMAs). As a result, five pCMAs from 54 physical parameters were screened out. Furthermore, different models were built by different combinations of pCMAs, and their predictive robustness of 43 batches was evaluated on the basis of the validation set. Finally, the tap density(D_c) of wet granules obtained from wet granulation and the angle of repose(α) of raw materials were identified as the critical material attributes(CMAs) affecting the hygroscopicity of the contents of Guizhi Fuling Capsules. The prediction model established with the two CMAs as independent variables had an average relative prediction error of 2.68% for samples in the validation set, indicating a good accuracy of prediction. This paper proved the feasibility of predictive modeling toward the control of critical quality attributes of Chinese medicine oral solid dosage(OSD). The combination of the continuous quality improvement, the industrial big data and the process modeling technique paved the way for the intelligent manufacturing of Chinese medicine oral solid preparations.

Analysis on 1 500 adverse reactions of Guizhi Fuling Capsules based on spontaneous response system / 中国中药杂志

To understand the characteristics of adverse reactions and find early warning signs after intake of Guizhi Fuling Capsules. The 1 500 adverse reaction(ADR) cases of Guizhi Fuling Capsules obtained by spontaneous reporting system(SRS) from 2008 to 2017 were analyzed by proportional reporting ratios method(PRR), Bayesian confidence propagation neural network method(BCPNN) and propensity score method. The number of ADR reports increased year by year, and reached the peak in the fourth quarter of 2014. A total of 1 500 ADR cases were monitored, including 10 severe ADR cases. There were a total of 934 cases aged between 18-44 years old, accounting for 62.27%. All patients were orally administered. Among them, 1 398 patients received a single dose according to the package insert, and 57.4% had ADR within 24 h. The top five clinical manifestations of ADR were gastric dysfunction, abdominal pain, nausea, vomiting and rash, which mainly damaged the digestive system. The ADR signals were analyzed. PRR suggested that "gastric dysfunction" and "abdominal pain" were the early warning signals of Guizhi Fuling Capsules. BCPNN suggested that "nausea" and "abdominal pain" were the early warning signals of Guizhi Fuling Capsules. After the propensity score weighting method was used to control the confounding factors, the warning signals remained unchanged. The results show that Guizhi Fuling Capsules has fewer adverse reactions and is relatively safe. This study provides a basis for studying ADR of Guizhi Fuling Capsules, and guidance for drug vigilance and risk management of Guizhi Fuling Capsules.
