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
目的:系统评价盐酸安非他酮缓释片和盐酸氟西汀片治疗抑郁症的有效性及安全性,为其临床应用提供依据。方法:计算机检索Cochrane图书馆临床对照试验资料库、Ovid-medline全文数据库、PubMed、Embase、中国期刊全文数据库、万方数字化期...目的:系统评价盐酸安非他酮缓释片和盐酸氟西汀片治疗抑郁症的有效性及安全性,为其临床应用提供依据。方法:计算机检索Cochrane图书馆临床对照试验资料库、Ovid-medline全文数据库、PubMed、Embase、中国期刊全文数据库、万方数字化期刊库、维普数据库和中国生物医学文献数据库中盐酸安非他酮缓释片对比盐酸氟西汀片治疗抑郁症的有效性与安全性的随机对照试验(RCT),提取资料后采用Rev Man 5.3统计软件进行Meta分析。结果:共纳入9项RCT,合计1 106例患者。Meta分析,盐酸安非他酮缓释片与盐酸氟西汀片治疗抑郁症的有效性无明显差异[OR=1.13,95%CI(0.87,1.48),P>0.05];不良反应发生率与盐酸氟西汀片治疗抑郁症比较也无明显差异[OR=1.13,95%CI(0.91,1.41),P>0.05]。结论:盐酸安非他酮缓释片和盐酸氟西汀片治疗抑郁症具有相似的疗效及不良反应。展开更多
