含有巴戟天寡糖的药物组合物及其制备方法 技术领域
本发明提供一种含有中药有效成分的组合物以及制备方法, 尤其是含有巴 戟天寡糖的组合物。 背景技术
巴戟天是茜草科植物
Figure imgf000003_0001
Hmv的干燥根。巴戟天提取物中的 有效成分——巴戟天寡糖抗抑郁的药理作用已经有很多记载。 为了便于服用, 生产者首先想到将其制成便于携带的含有巴戟天寡糖的固体制剂, 如胶囊。
巴戟天寡糖胶囊是由巴戟天寡糖加入适量辅料制成颗粒后装入胶囊而成。 ZL200410056935.8给出的巴戟天寡糖胶囊采用流化床或湿法制粒, 由于巴戟天 寡糖较易吸潮, 不易制粒, 因此为了能够实现湿法制粒, 研制者加入了包括硬 质酸镁、 淀粉、 微晶纤维素和聚乙烯聚吡咯烷酮的大量辅料来达到制粒的目的, 以保证其流动性和成型性, 由于大量的辅料的存在, 制成的胶囊患者每次服用 量为 3粒 2号胶囊, 日服 3次, 抑郁症患者临床依从性一般较差, 用药的原则 是越简便越好。
流化床制粒还有一个弊端是受热温度较高、 受热时间较长, 使巴戟天寡糖 粘结变性, 制剂成型后吸湿性增强, 生产环境必须严格控制湿度, 加大了生产 的可行性难度, 产品保质期缩短, 严重受热后会造成活性的部分降低。
为了实现在保证患者药物的服用剂量的前提下尽量减少服用粒数的目的, 必须大幅减少辅料用量, 经过研究发现, 减少辅料后通过湿法制粒来制备巴戟 天寡糖胶囊的方案不可行, 因此降低患者服用粒数的同时, 加强患者的依从性, 降低辅料用量, 简化工艺过程成为改良巴戟天寡糖胶囊的重中之重。 发明内容
为了达到改良现有巴戟天寡糖胶囊剂型和制剂工艺的目的, 发明人进行了 大量的摸索排查, 在现有技术的基础上进行了巴戟天寡糖胶囊的工艺改进研究, 用详尽的实验数据考察了辅料品种、 制粒条件、 颗粒的水分、 流动性、 溶出度 等指标, 最终得到了本发明的辅料简单、 有效成分含量多的巴戟天寡糖制剂。
本发明的目的在于提供一种含有巴戟天寡糖的药物组合物, 该药物组合物 中的药用辅料在该组合物中占较低的比例, 降低了辅料用量, 从而降低了患者 的服用量, 相应增加了服用单位药物中活性成分的比例, 保证了药效不变。
本发明的目的还在于提供一种含有巴戟天寡糖的药物组合物的制备方法, 通过该方法可以降低组合物中药用辅料的含量, 提高单位组合物的药效。
本发明的目的还在于提供一种含有巴戟天寡糖的药用组合物在制备治疗抗 抑郁症的药物中的应用。
为了达到上述目的, 本发明提供一种含有巴戟天寡糖的药物组合物, 该药 物组合物包括巴戟天寡糖和药用辅料; 所述的药用辅料包括微晶纤维素、 淀粉、 微粉硅胶中任一或其组合。
本发明的药物组合物中的巴戟天寡糖为具有抗抑郁作用的活性成分,包括菊 淀粉型寡糖 3糖〜 9糖, gp, 本发明所采用的巴戟天寡糖是含有菊淀粉型寡糖 3 聚体、 菊淀粉型寡糖 4聚体、 菊淀粉型寡糖 5聚体、 菊淀粉型寡糖 6聚体、 菊 淀粉型寡糖 7聚体、 菊淀粉型寡糖 8聚体、 菊淀粉型寡糖 9聚体中任一成分或 其组合的混合物。 巴戟天寡糖的结构如下:
Figure imgf000004_0001
其中, n=l为 3糖; n=2为 4糖; n=3为 5糖; n=4为 6糖; n=5为 7糖; n=6为 8糖; n=7为 9糖。
本发明药物组合物中含有的巴戟天寡糖优选为含有菊淀粉型寡糖 3糖〜 9糖 中任一种或者一种以上成分任意组合的混合物, 为了保证该药物组合物的质量 和疗效, 该原料巴戟天寡糖中含有的菊淀粉型寡糖的总量优选不少于 50.0%wt, 例如可为 50.0%〜99.0%; 更优选为同时包括菊淀粉型寡糖 3聚体(C18H32016,简称 3糖)、 菊淀粉型寡糖 4聚体(也称耐斯糖, nystose, C^O,! , 简称 4糖)、 菊淀粉型寡 糖 5聚体(也称 1F-果呋喃糖基耐斯糖, lF-fructofuranosyl nystose, C30H52O26, 简称 5糖)、菊淀 粉型寡糖 6聚体((2→1)果呋喃糖基蔗糖 hexasaccharide, C36H62031, 简称 6糖)、 菊淀粉 型寡糖 7聚体(hep tasaccharide, C42H72036,简称 7糖)、菊淀粉型寡糖 8聚体(C48H82041, 简称 8糖)和菊淀粉型寡糖 9聚体(C54H92046, 简称 9糖) 的混合物, 同样地, 为了保 证该药物组合物的疗效, 该混合物的巴戟天寡糖中 3~9糖的量不低于 50.0%wt, 例如可为 50.0%〜99.0%,经过检测, 该巴戟天寡糖中 5糖的量不低于 5.0%wt, 一 般随着精制纯化过程的不同, 巴戟天寡糖中 5糖的量在很大范围内浮动, 例如可 为 5.0%〜95.0%。
本发明的目的是在保证药效的基础上降低药用辅料的用量、改善药物性质和 患者服用依从性, 因此, 药用辅料优选微晶纤维素、 淀粉、 微粉硅胶中任一或 其组合, 更优选微晶纤维素、 淀粉或微粉硅胶, 最优选微晶纤维素或微粉硅胶。
为了达到治疗抑郁症的药效,本发明的组合物优选是药物制剂(药剂)形式, 其中, 巴戟天寡糖与药用辅料的重量配比为 8: 1〜1: 10, 优选 4: 1〜1: 4。
本发明的药用组合物中的原料巴戟天寡糖可以通过市售购得,也可以自行提 取得到, 优选用下述方法制得: 取巴戟天生药, 用为该巴戟天生药重量至少 2 倍量的 (优选 8倍)水提取 N次, N 1, 得到水提取物, 以至少为生药重量 1 倍量的活性碳装柱,例如活性碳为生药重量 2〜10倍,将水提取物用水溶解(例 如 lg/ml)上柱吸附,用水洗脱清洗除去单糖、双糖成分,用浓度为 10〜98%(wt), 优选浓度为 20%〜80%的乙醇洗脱巴戟天寡糖, 收集乙醇洗脱液, 浓缩、干燥, 即得巴戟天寡糖, 所述的巴戟天寡糖为菊淀粉型寡糖 3聚体(C18H32016)、 菊淀 粉型寡糖 4聚体 (C24H42021 )、 菊淀粉型寡糖 5聚体(C3。H52O26)、 菊淀粉型寡 糖 6聚体( C36H62O31 )、 菊淀粉型寡糖 7聚体(C42H72O36)、 菊淀粉型寡糖 8聚 体(C48H82041 )和菊淀粉型寡糖 9聚体(C54H92O46)。 为了便于患者服用以及携带和贮存, 本发明的药物组合物优选为口服制剂, 例如胶囊剂、 片剂、 颗粒剂、 散剂或锭剂, 更优选胶囊剂。
可以制备固体口服制剂例如胶囊剂的药用辅料很多, 但是这些公知的药用 辅料并不适合于制备含有巴戟天寡糖做为药用成份的制剂(胶囊), 例如, 现有 技术中巴戟天寡糖制剂工艺中的辅料包括硬质酸镁、 淀粉、 聚乙烯聚吡咯烷酮、 微晶纤维素等等, 辅料多而且杂, 相当于患者服用了大量的不起任何治疗作用 的辅料。 而仅仅考虑减少辅料的品种和用量, 又达不到辅料在制剂中所起到的 作用, 例如, 采用硬质酸镁和 /或聚乙烯聚吡咯烷酮等常规的辅料被大量的实验 证明不能用来制备巴戟天寡糖的固体口服制剂。
为了实现在保证患者药物有效成分的服用剂量的前提下尽量减少服用粒 数、 增强患者顺应性, 以及改善药物性质, 提高稳定性的目的, 必须大幅减少 辅料用量, 经过研究发现, 减少辅料后通过湿法制粒来制备巴戟天寡糖胶囊的 方案不可行, 而流化床制粒还有一个弊端是受热温度较高、 受热时间较长, 使 巴戟天寡糖粘结变性, 制剂成型后吸湿性增强, 生产环境必须严格控制湿度, 加大了生产的可行性难度, 产品保质期缩短, 严重受热后会造成活性的部分降 低。 因此选用干挤制粒的方法进行工艺研究。 随着干法制粒技术的提高和相关 设备的不断完善, 干法制粒技术越来越多了应用到了中药的生产制剂中, 目前 普遍采用轮转式干压机或滚筒平压制粒机完成, 其优点是在中药浸膏粉中添加 适量辅料后, 在生产过程中不必加入润湿剂和粘合剂, 可直接制粒, 无需湿润、 混合、 干燥等过程, 工艺简便, 减少了工艺过程, 避免受热, 能有效保证中药 质量, 同时大大降低辅料的用量。
本发明的辅料仅保留微晶纤维素、 淀粉、 微粉硅胶中任一或其组合, 尤其 是微晶纤维素、 淀粉或微粉硅胶中任意一种, 同时采用干挤制粒法制粒, 可以 达到本发明的减少辅料、 改善药物性质、 增强药效的目的。
在现有技术中, 本领域技术人员公知巴戟天寡糖与辅料的比例基本上为 1 :
1或者巴戟天寡糖的量更少, 经多次试验, 本发明的药用组合物中, 巴戟天寡糖 与药用辅料之间的比例最高可达到 8: 1或者更高, 最低也可达到 1 : 10, 这样, 采用干挤制粒技术制粒成型,以胶囊剂为例,可以制成每粒含巴戟天寡糖 150mg、 200mg两种规格的胶囊。 通过 II期临床研究对治疗剂量的探索, 最终确定巴戟 天寡糖胶囊的服用量为每次 150mg, 每日 2次。 按照原工艺需每次服 3粒胶囊, 本发明工艺, 在保持原料药巴戟天寡糖制备工艺不变的前提下, 将制粒工艺改 为 150g巴戟天寡糖加入 150g辅料, 干挤制粒, 装入胶囊, 每粒含巴戟天寡糖 150mg, 每次只需服用 1粒, 可降低患者服用粒数, 加强患者的依从性, 降低辅 料用量, 同时可在一般环境生产, 改善了生产的可行性, 简化了工艺。
本发明的药物组合物优选为胶囊剂。 筛选工作如下, 试验结果见下表:
1.辅料的筛选
本实验依次选择了包括硬质酸镁、 淀粉、 聚乙烯聚吡咯焼酮、 微粉硅胶、 微晶纤维素等等常规的辅料, 其中, 微晶纤维素最佳。
巴戟天寡糖用量: 100g;
制粒设备: FREUND干挤制粒机;
工作压力: 100kg/cm2; 挤压器转速: 4rpm; 送料器转速: 30rpm;
编号 辅 料 结 果
I 淀粉 50g 干挤制粒 类白色颗粒
II 淀粉 100g 干挤制粒 类白色颗粒
III 微晶纤维素 50g 干挤制粒 类白色颗粒
IV 微晶纤维素 100g 干挤制粒 类白色颗粒 结论: 从上述试验结果可以看出, 在不加入粘合剂的情况下, 淀粉、 微晶 纤维素均具有较好的可压性和成型性。 单独采用淀粉或者微粉硅胶也可得到较 好的效果, 但是综合各方面的因素, 更优选微晶纤维素。
2、 巴戟天寡糖及颗粒引湿性考察
由于巴戟天寡糖极易吸湿性, 测定其吸湿平衡点与添加辅料后吸湿性的变 化是很有必要的。 把制得的颗粒及巴戟天寡糖进行吸湿度的测定。 具体操作如 下, 取样品适量放于直径 2cm的秤量瓶中均匀铺开, 置恒温恒湿器中, 设置为 25°C和不同的湿度, 放置 12小时, 进行考察, 以在每个湿度的吸湿增重作图, 湿度为 X轴, 吸湿增重量(%) 为 Y轴; 结果见下表。

本发明还提供了一种上述的药物组合物的制备方法, 该方法包括:
( 1 )取巴戟天生药, 用至少为该巴戟天生药重量 2倍量的水提取 N次, 这 里的 N为自然数, 优选 N≥l, 得到水提取物, 再以至少为生药重量 1倍量的活 性碳吸附(活性碳装柱, 水提取物上柱吸附),用水清洗除去单糖、双糖成分后, 用浓度为 10%〜98%的乙醇洗脱, 得到含有巴戟天寡糖的洗脱液, 浓缩、干燥, 得到巴戟天寡糖; (2)在步骤(1 )得到的巴戟天寡糖中加入药用辅料, 该药用辅料包括微晶 纤维素、 淀粉、 微粉硅胶中任一或其组合, 混匀, 干法制粒, 即得。
上述制备方法中优选加 2-10倍药量 (重量) 的水煎煮 2-5次, 每次 0.5-2.5 小时。 用蒸馏水清洗除去单糖、 双糖成分; 再用 2-8倍柱体积的 25-45%的乙醇 洗脱。收集乙醇洗脱部分, 减压浓缩至相对密度 d=l .15-1.20 ( 50°C ), 优选喷雾 干燥, 即可得到巴戟天寡糖。
在本发明的优选实施例中, 辅料仅仅是微晶纤维素一种, 制法为: 取巴戟 天寡糖, 加入微晶纤维素, 混匀, 干法制粒, 装入胶囊, 即得。
干法制粒是本领域的常规技术, 在制备固体颗粒剂型的时候, 其应用的范 围不如湿法制粒广。 本发明的干法制粒与现有技术最常用的湿法制粒比较:
1、现有技术湿法制粒的巴戟天寡糖胶囊:巴戟天寡糖 50g,加硬脂酸镁 7.5g, 淀粉 75.0g、 微晶纤维素 47.5g, 聚乙烯聚吡咯垸酮 5.0g, 混匀, 用 3%羟丙基甲 基纤维素制成颗粒, 干燥, 装入胶囊, 制成 1000粒, 即得。
2、 按照本发明的工艺制备样品: 1.取巴戟天寡糖 150.0g, 加入微晶纤维素 150.0g, 混匀, 制成颗粒, 装入胶囊, 制成 1000粒, 即得(150mg/粒)。
3、 取巴戟天寡糖 200.0g, 加入微晶纤维素 100.0g, 混匀, 制成颗粒, 装 入胶囊, 制成 1000粒, 即得 (200mg/粒)。
对两种工艺制剂情况进行比较。 结果见下表。
Figure imgf000009_0001
结论: 通过与原工艺比较, 结果表明新的制剂工艺工艺过程简单、工艺条件 适宜大生产, 稳定性较好、 减少辅料用量, 降低了制剂成本, 减少了患者口服 药量, 本发明产品与已有的湿法制粒的制剂比较, 药效不变。
同时也测试了单独用淀粉或微粉硅胶做为辅料以及微晶纤维素、淀粉和微粉 硅胶组合做为辅料的含有巴戟天寡糖的固体口服制剂, 例如胶囊剂, 其优异性 能高于现有技术最常用的湿法制粒的产品, 但逊于单独采用微晶纤维素、 淀粉 或微粉硅胶中任一做辅料的产品, 最优选是微晶纤维素做为辅料的药物组合物。
稳定性考察: 对巴戟天寡糖原料药和本发明的巴戟天寡糖胶囊 150mg/粒、 200 mg/粒各三批产品进行了稳定性考察, 第 3、 6、 9、 12、 24月取样分析结果, 与 0月数据进行比较, 未见质量差异。
本发明还提供了上述的药用组合物在制备治疗抗抑郁症的药物中的应用。 1、 药效学试验
在抑郁模型动物试验中, 巴戟天寡糖显示显著的抗抑郁药效作用。在评价抗 抑郁作用的药理学指标上, 巴戟天寡糖显示与经典抗抑郁剂地昔帕明相似效应。
1. 1 小鼠悬尾抑郁模型
在经典的小鼠悬尾模型上, 口服巴戟天寡糖显著减少小鼠不动时间,其有效 剂量为 25~50 mg/kg。
1.2小鼠强迫性游泳抑郁模型
在经典的小鼠强迫性游泳抑郁模型上,口服巴戟天寡糖显著减少小鼠不动时 间, 其有效剂量为 50~75mg/kg (p<0.01), 且重复性良好。
1.3大鼠强迫性游泳抑郁模型
在大鼠强迫性游泳抑郁模型上, 口服巴戟天寡糖 12. 5~25 mg/kg。 显著减少 大鼠不动时间, 且重复性良好。
在评价抗抑郁作用的药理学指标上,巴戟天寡糖显示了与经典抗抑郁剂地昔 帕明相似的效应:
①使皮层、 海马和下丘脑激活态下的腺苷酸环化酶活性增强。
②增强皮层和海马 G蛋白亚单位 GSa的 mRNA表达。
③提高皮层和海马中神经生长因子(NGF)和脑源性神经生长因子(BDNP) 的 mRNA的表达。
④对皮质酮所致 PC12细胞的损伤具有保护作用。
1.9药物诱发抑郁模型上的药效评价
增强 5-羟色胺酸(5-HTP)诱导甩头试验; 增强育亨宾毒性试验; 阿朴吗啡 降温试验三个药物相互作用模型灌胃给药巴戟天寡糖的药效评价, 试验结果表 明: 巴戟天寡糖在行为抑郁模型上有效的剂量范围内, 连续 3 天灌胃给药 12.5-50mg.kg-l可增强 5-HT神经功能, 表现为显著增强 5-HTP诱导的小鼠甩头 行为。连续 3天灌胃给药 6.25-250 mg.kg-1未见增强育亨宾毒性作用, 说明其对 NE神经系统功能没有影响。 此外, 该药还可以增强 DA神经功能, 表现为一次 灌胃用药 200和 400mg.kg-l可增强阿扑吗啡降低小鼠体温的作用。 结论: 巴戟 天寡糖主要通过促进 5-HT神经功能发挥抗抑郁作用, 同时具有促进 DA神经功 能药理学作用。
2.0大鼠前额皮层单胺水平调节作用
巴戟天寡糖灌胃给药后对大鼠脑内单胺递质水平试验,试验结果表明:灌胃 给予巴戟天寡糖 (每天二次, 连续 7天) 12.5, 50 mg kg显著提高正常大鼠前 额皮层 5-HT水平, 在 25-50mg/kg剂量范围内显著提高 DA及 5-HT/5-HIAA比 值,在 12.5-50mg/kg剂量下具有提高 NE水平的趋势,但无显著性差异。表明巴 戟天寡糖可增强前额皮层 5-HT和 DA神经功能。
上述实验只是本发明的众多药理实验的一部分,更多的实验数据由于篇幅所 限暂欠奉。实验证明,本发明含有巴戟天寡糖的药用组合物可以用来治疗抑郁症。
临床研究也表明: 本发明的药物组合物治疗抑郁症的疗效优于安慰剂, 非劣 于氟西汀的疗效;对中医证候的疗效优于氟西汀;对抑郁伴发的焦虑有效;而且, 安全性好。 具体实施方案
