技术领域
本发明属于药物制剂技术领域,尤其涉及一种胞磷胆碱盐及其制备方法与应用。
背景技术
胞磷胆碱是内源性合成磷脂酰胆碱的中间体,是构建生物膜的重要成分。中枢神经损伤后,胞磷胆碱参与修复和再生,起神经保护作用;在神经介质的转移和生物电的传导中也起重要作用。对急性中风、外科手术后引起的神经损伤、意识障碍,对帕金森综合征、痴呆症、青光眼等有明显的临床治疗效果。
目前研究表明胞磷胆碱有助于脑卒中后遗症、脑卒中后偏瘫患者的上下肢功能的恢复,可与促进脑代谢及脑循环的药物同用。也可适用于急性中毒、感染、大面积脑梗死所致的昏迷和意识障碍、缺血性脑血管病、血管性痴呆、耳鸣及神经性耳聋。
相关技术中所采用的胞磷胆碱盐及其制备方法性能单一且不够稳定,容易吸湿而变质,不具有广泛的应用前景。

设定温度:25.0℃,设定相对湿度:65.0%
实际温度:25.0℃,实际相对湿度:65.0%
称重采用十万分之一电子分析天平
试验结果如表1所示:
表1湿度测试结果
从上表可以看出,相同条件下各组分单独的吸湿度都很大、吸湿性强,而相应的胞磷胆碱盐,基本不吸湿,产品十分稳定。
试验例2。
本试验例涉及实施例6-10和对比例4中氨基酸的溶出度和溶解性的检测结果比较。
溶出度检测方法:分别取实施例6-10所制备得到的片剂6片,照《中国药典》2015年版通则溶出度与释放度测定法第二法,以0.1%吐温80溶液900ml为溶出介质,转速为75rpm,依次于10、30、60、90、120min取样,离心,取上清液作为供试品溶液,分别计算每片溶出量,并计算平均值,结果如表2。
表2溶出度测试结果
由以上数据可以看出,本申请中实施例制备的片剂与对比例4制备的片剂相比,胞磷胆碱盐化合物溶出度高。
本试验例同时提供:以实施例6和实施例10中制得的产品为实验样品的溶解性试验。
分别取实验样品0.3g(临床推荐使用剂量:按胞磷胆碱L-精氨酸盐计,每1L水中添加3000mg),置纳氏比色管中,加水稀释至50ml,在25℃±2℃上下翻转10次,呈无色透明的澄清溶液,即供试品均全部溶解,静置30min后,未出现浑浊现象或沉淀生成。
以上实验说明本发明制得的产品溶解性良好。
试验例3。
本实验例涉及实施例6-10和对比例3中氨基酸的溶出度的稳定性考察结果比较。
稳定性考察方法:将实施例6-10、对比例3所制备的片剂在加速试验条件(温度40℃±2℃、相对湿度75%±5%)下放置,并分别于0、3、6月时间点考察溶出度的变化情况。溶出度检测方法同试验例1。结果如表3。
表3时间考察溶出度的变化结果
由以上数据可知,各样品在加速条件下放置6个月后,实施例6-10制备的片剂各个取样点的溶出度略有降低,变化较小;对比例3制备的片剂变化幅度相对较大;说明了采用本发明所提供的工艺制备的胞磷胆碱盐固体分散体片剂稳定性更好。
试验例4。
本试验例提供实施例2和4的产品的水中稳定性试验。
1、试验目的:本试验以实施例2和实施例4中制得的产品为实验样品。因考虑临床推荐方式为饮水给药,故需验证本发明在饮用水中的稳定性。
2、试验方法:取供试样品4g(按临床推荐高剂量浓度2倍计),置1000mL量瓶中,加饮用水适量溶解后,用饮用水稀释至刻度,摇匀,备用。分别于1、2、3、6、12、24、36h末取样,检测溶液的性状和活性成分的含量(以0h为100%计)。
3、试验结果及分析:结果见表4。
由表4可知,按实施例2和实施例4制得的样品,在饮用水中溶解36h后,仍为无色澄清溶液,活性成分含量变化在8.5%之内,说明本发明提供的样品在饮用水中稳定性良好。
表4饮用水中稳定性试验结果
试验例5。
本试验例提供实施例1、5的产品的加速稳定性试验。
1、试验目的:考察本发明制得产品的稳定性。
2、试验方法:本试验以实施例1和实施例5中制备方法制得的3批产品为实验样品。
取样品3批,按市售包装,在温度40℃±2℃、相对湿度75%±5%的条件放置6个月,分别于第1、2、3、6个月末分别取样一次,检测样品的性状、活性成分含量、溶解性。
3、试验结果及分析:结果见表5。
由表5可知,3批产品经过6个月加速试验考察,性状、溶解性均符合规定,胞磷胆碱盐的含量均在98.0-100.0%范围内。
试验结果表明,本发明制得的产品在高温和高湿条件下稳定性良好。
