取本品,剪成1cm2大小的薄膜6片,分别用两层筛孔内径为 2. 0mm 的不锈钢丝夹住,照崩解时限测定方法,观察本品完全溶解的时间。
2、拉伸性能的测试
取实施例制备的未经切割的口腔速溶膜适量,裁取 100mm×20mm 尺寸的试样 5 个,试样的边缘须平滑、无缺口和损伤。 首先进行膜剂厚度测定, 然后在拉断力测定仪上进行拉伸性能的测试。将膜放置在拉断力测定仪上下两个夹具中, 使试样与上下夹具的中心连线重合、夹具松紧适宜, 两夹具间距为 60mm。 以 100± 10mm/min 的速度开动试验机,试样断裂后, 读取拉伸强度和拉伸率。
溶化时限 s | 拉伸强度 N | 拉伸率 % | |
实施例1 | 34 | 11 | 6.2 |
实施例2 | 36 | 12 | 5.2 |
实施例3 | 26 | 16 | 7.6 |
对照例1 | 32 | 11 | 5.8 |
对照例2 | 36 | 10 | 6.1 |
从表中可以看出,本发明提供的中药制剂口溶膜溶化时间短,拉伸强度高,适于在口中含化服用。另外,从实施例3和对照例1对比可以看出,通过微晶纤维素未经过改性,得到的口溶膜的溶化时限、拉伸强度、拉伸率都得到了提高。
将上述的口腔速溶膜存储于铝箔袋中,于25℃、50%RH湿度下存储6个月后,重复上述试验,结果如下:
溶化时限 s | 拉伸强度 N | 拉伸率 % | |
实施例1 | 35 | 10 | 6.0 |
实施例2 | 37 | 11 | 5.0 |
实施例3 | 27 | 16 | 7.4 |
对照例1 | 52 | 6 | 5.1 |
对照例2 | 45 | 8 | 4.8 |
从表中可以看出,实施例3相对于对照例2来说,通过加入1,5-D-脱水果糖可以显著延长该口腔速溶膜的长期存储后的制剂稳定性,实施例2中的制剂的存放后出现了拉伸率、溶化时间的明显延长。
药效试验资料
对小鼠流感病毒性肺炎的实验研究
试验方法:
取13-15g小鼠,按体重随机分为8组,分别为正常对照组,病毒对照组,供试药(本发明实施例1~3和对照例1~2), 阳性对照药利 巴韦林颗粒组,每组10只。除正常对照组外,小鼠用乙醚轻度麻醉, 以15LD50流感病毒液(FM1)滴鼻感染,每只0.05ml。感染后开始给药 ,每天1次,连续5天。第6天称取小鼠体重后,固定、放血、解剖,摘 取全肺称重,逐个计算肺重量指数,并求出肺指数抑制率。
肺重量指数=[肺重(g)/体重(g)]×100%
肺指数抑制率%=病毒对照组肺重量指数增长值-试验组肺重量指数增长值/病毒对照组肺重量指数增长值×100%。
肺重量指数值大,表示肺病变程度严重。将各组肺指数值进行t检验 ,比较组间差异性。见下表。
与病毒对照组相比 *P<0.05,**P<0.01。
从表中可以看出,本发明提供的药物具有较好的抗肺癌感染的疗效,对流感病毒感染小鼠引起的肺炎均有不同程度的抑制作用,小鼠体重增加、肺重量指数值降低明显。
