MHSRT were prepared by the film coating method. The in vitro drug release rate of MHSRT and the commercial tablets Fortamet? made in the United States of America in water was fitted with zero order kinetic equation, and Ritger-Peppas kinetic equation in 0.1 M HCl and pH 6.8-phosphate buffer, respectively. The similarity factor f2 values of MHSRT in three different dissolution medium were 82, 80 and 74, respectively in comparison with imported Fortamet?, which were all greater than 50. The results of storage-stability showed that MHSRT were stable for at least 6 months under stress condition (40℃ ± 2℃, RH 75% ± 5%). Therefore, in this study, MHSRT were successfully prepared using optimized formulation technologies that meet mass produce. The in vitro release behavior of MHSRT was almost similar to that of imported Fortamet?.展开更多

Methods: From October 2016 to January 2018, 126 patients with cancer pain were enrolled and divided into 4 groups, 39 patients in group A (directed TCM permeation), 26 patients in group B (oxycodone sustained-release tablets), 32 patients in group C (Chinese medicine directed drug penetration + oxycodone sustained-release tablets), and 29 patients group D (Chinese medicine directed drug penetration + oxycodone sustained-release tablets + nimesulide sustained release tablets), according to KPS scores. Results: Transdermal preparations of traditional Chinese medicine can significantly alleviate cancer pain. For the treatment of moderate to severe cancer pain, the Chinese medicine transdermal preparation can reduce the dosage of oxycodone sustained-release tablets. At the same time, the patient's KPS and NRS scores were significantly reduced. Moreover, the transdermal preparation of traditional Chinese medicine has a better therapeutic effect on visceral pain. Conclusion: The traditional Chinese medicine tra_nsdermal preparation combined with western medicine for the treatment of cancer pain may be a new method for the treatment of cancer pain.展开更多
