由本发明所制备得到的美索舒利薄膜衣片, 其性状、 硬度、 脆碎度、 片重差异均符合 要求, 且溶出度较高, 且均能达到 90%, 符合要求。
美索舒利薄膜衣片的 10天影响因素试验结果表明: 薄膜衣片在高温、 高湿、 光照下放 置 10天, 含量、有关物质无显著性变化, 质量基本稳定, 表明, 处方科学可行, 工艺合理、 重现性好。 但高湿 10天薄膜衣片表面有轻微吸潮, 溶出度有所下降, 提示选择包装时要注 意防潮。 因此, 产品需要密封干燥处贮存。
进一步的, 根据本发明的实施例, 对本发明所述美索舒利薄膜衣片的内包材进行选择, 采用聚氯乙烯泡罩 +双面复合铝膜袋对所述美索舒利薄膜衣片进行包装。由此,密封性较好, 能够有效防止美索舒利薄膜衣片吸潮, 能有效保证本品的长期稳定性, 有利于美索舒利薄 膜衣片的长期储存。

根据本发明的实施例, 本发明具有以下有益效果: 1、 根据本发明的实施例, 通过采用微晶纤维素作为填充剂, 不仅药物可压性好, 崩解 速度快, 溶出度高, 且可提高薄膜衣片的硬度和片面的光洁度, 加快美索舒利薄膜衣片的 崩解, 从而提高美索舒利的溶出度。 当采用聚维酮 K30作为粘合剂、 以及采用交联聚维酮 为崩解剂时, 美索舒利薄膜衣片的崩解速度较快, 溶出度较高。
2、 根据本发明的实施例, 在原辅料的前处理上, 先将美索舒利和填充剂混合进行微粉 化后, 能够使得难溶性的美索舒利充分的分散在填充剂中, 然后再与其他辅料混合, 采用 这种方法制成的美索舒利薄膜衣片, 其溶出度可以显著得到改善。

下面详细描述本发明的实施例。 下面描述的实施例是示例性的, 仅用于解释本发明, 而不能理解为对本发明的限制。 实施例中未注明具体技术或条件的, 按照本领域内的文献 所描述的技术或条件或者按照产品说明书进行。 所用试剂或仪器未注明生产厂商者, 除美 索舒利原料为自制外, 其它辅料均为可以通过市购获得的常规产品。
实施例 1: 处方研究
由于主药美索舒利几乎不溶于水, 且主药量也较大, 因此, 处方工艺的难点在于提高 本品的溶出度。在本实施例中,对规格为 lOOmg/片的美索舒利薄膜衣片的处方进行了研究, 具体而言, 由于美索舒利原料药水溶性及流动性均差, 考虑加入水溶性辅料及崩解剂促进 溶出, 设计了 9个处方, 见表 1。

按表 1中的处方, 采用湿法制粒工艺, 先制备得到美索舒利片芯, 测定溶出度, 制备方法具体如下:
( 1 ) 原辅料前处理: 将主药 (美索舒利)、 各辅料分别粉碎后, 主药过 60目筛, 辅料 过 80目筛, 备用;
(2) 配粘合剂:
当处方中的粘合剂选择聚维酮 K30 (PVPK30) 时, 称取 8克聚维酮 K30于烧杯中, 加纯化水 92克, 搅拌至澄清, 得 8%聚维酮 K30水溶液 I, 备用;
当处方中的粘合剂选择羟丙甲纤维素时, 称取 4克羟丙甲纤维素于烧杯中, 加纯化水 96克, 搅拌至澄清, 得 4%羟丙甲纤维素水溶液 I, 备用;
(3 )混合:称取处方量的主药、填充剂混合均匀后,再加入崩解剂交联聚维酮(PVPP) 混合均匀, 得混合物 Π;
(4)制软材及制粒: 将处方量的粘合剂水溶液 I加入混合物 II中, 制成软材, 将所得 软材过 18目不锈钢筛制粒, 得湿颗粒;
(5) 干燥: 将步骤 (4) 中所得到的药物湿颗粒于 60°C±5°C下干燥约 2h; (6) 整粒: 将经过干燥的药物颗粒过 18目不锈钢筛整粒, 得干颗粒;
(7) 总混: 干颗粒中加入处方量硬脂酸镁, 混合均匀, 得总混颗粒;
( 8)压片: 根据总混颗粒所测得含药量, 计算理论片重, 将压片机调整到适宜的填充 量, 控制压力使薄膜衣片的片芯硬度在 5〜7kg以内, 压片即得。
溶出度测定:
按中国药典 2010版溶出度项下的测定方法, 测定上述 9个处方在溶出介质中 45分钟 的溶出度, 其中溶出介质为磷酸盐缓冲液 (氢氧化钠 2.30g, 磷酸二氢钾 7.65g, 加水使溶 解为 1000ml, 用磷酸调 pH至 8.8), 溶出度测定结果见表 2。
表 2各薄膜衣片片芯处方的溶出度对比
Figure imgf000010_0001
从溶出结果看, 所设计的 9个处方在溶出介质中 45分钟的溶出度显示, 较优的处方为 处方 1、 处方 4、 处方 5、 处方 7, 其溶出度均达到了 80%以上。 由于美索舒利水溶性差, 而羟丙甲纤维素有阻溶作用, 可能会在样品留样期间影响溶出度, 加之其在水中完全溶胀 所需时间较长, 不利于工业化生产, 因此不优选其作为粘合剂。 但由于前期实验研究表明: 单独以乳糖为填充剂时, 工业大生产会出现裂片现象, 所以本发明在稀释剂的辅料选择上 不选用乳糖。 而微晶纤维素不仅能作为填充剂, 而且具备崩解剂的性能, 选取微晶纤维素 可达到良好的溶出效果。
故本研究确定以处方 4和处方 7为基础, 进一步考察筛选填充剂的最佳用量、 粘合剂 的浓度, 以及改进崩解剂的添加方式, 对处方和制剂工艺进行进一步优化。
实施例 2: 100 mg规格的美索舒利薄膜衣片处方及工艺优化
本研究根据中国药典 2010版对薄膜衣片的剂型要求, 参照 CDE颁布的 《化学药物制 剂研究基本技术指导原则》, 结合薄膜衣片的特点, 以性状、 硬度、 脆碎度、 崩解时间、 溶 出度等为考察指标, 对本品处方所使用辅料的种类和用量进行了进一步的筛选。

调整微晶纤维素的比例和用量, 考察稀释剂 (在本文中, "填充剂"和 "稀释剂"可以 互换使用) 不同用量对压片成形性和溶出度的影响, 具体处方和结果如下:
本研究采用微晶纤维素作为稀释剂, 微晶纤维素不同用量的处方见表 3, 表 3所示为制 备 1000片美索舒利薄膜衣片的处方量。 按照表 3所示处方及实施例 1中所述的制备方法, 以 1000片 /批的批量进行制粒压片,理论片重为 240 mg,然后测定制备获得的美索舒利薄膜 衣片的硬度、 脆碎度、 崩解时间和溶出度, 筛选填充剂。 结果见表 3。

Figure imgf000011_0001
由表 3的结果可以看出, 微晶纤维素按上述 4个处方的用量, 溶出度均能达到 80%以 上, 其中以处方 12的崩解和溶出度最好。
(2) 粘合剂的筛选
选取 PVP-K30作为粘合剂, 并配制不同浓度的水溶液对其粘合效果进行了比较研究, 具体如下:
按照表 4所示的处方以及实施例 1中的制备方法,制备获得美索舒利薄膜衣片的片芯, 制备过程中观察美索舒利干颗粒情况,并测定制备获得的美索舒利薄膜衣片的片芯的硬度、 脆碎度、 崩解时间和溶出度, 处方和测定结果见表 4, 其中, 表 4所示处方为制备 1000片 美索舒利薄膜衣片的片芯的处方量。
其中, 在处方 14中, 粘合剂的配制方法为: 称取 4克聚维酮 K30于烧杯中, 加纯化 水 96克, 搅拌至澄清, 得 4%聚维酮 K30水溶液; 其中处方 15中, 粘合剂的配制方法为: 称取 8克聚维酮 K30于烧杯中, 加纯化水 92克, 搅拌至澄清, 得 8%聚维酮 K30水溶液; 其中处方 16中, 粘合剂的配制方法为: 称取 12克聚维酮 K30于烧杯中, 加纯化水 88克, 搅拌至澄清, 得 12%聚维酮 K30水溶液; 其中处方 17中, 粘合剂的配制方法为: 称取 6 克聚维酮 K30于烧杯中, 加纯化水 94克, 搅拌至澄清, 得 6%聚维酮 K30水溶液; 其中处 方 18中, 粘合剂的配制方法为: 称取 15克聚维酮 K30于烧杯中, 加纯化水 85克, 搅拌 至澄清, 得 15%聚维酮 K30水溶液。

在本实施例中, 考察了崩解剂的用量以及崩解剂的添加方式对美索舒利薄膜衣片片芯 的影响, 具体如下:
按照表 5所示的配方以及实施例 1中的制备方法, 制备获得美索舒利薄膜衣片片芯。 需要说明的是, 在本实施例中, 崩解剂的添加方式为两种: 内加法和外加法, 内加法为在 步骤 (3 ) 中加入崩解剂, 外加法是指在步骤 (7 ) 中加入崩解剂。 然后测定制备获得的美 索舒利薄膜衣片片芯的硬度、 脆碎度、 崩解时间和溶出度, 测定结果见表 6。 其中, 表 5 所示的配方为制备 100片美索舒利薄膜衣片片芯的处方量。

从表 6的结果可以看出, 处方 20和处方 21溶出度结果差异不大, 说明减少一定量的 崩解剂仍可以保持较好的溶出, 同时还可以节约成本。 采用内外加法, 外加崩解剂可以促 进颗粒的崩解, 内加崩解剂则能加快颗粒的分散, 有利于提高溶出度。 从上述结果可以看 出, 处方 23的崩解时间和溶出度都能达到最优, 故确定 PVPP的用量及添加方式为: 内加 0.7g, 外加 0.5g。 因此, 暂定最佳处方为处方 23。
在本实施例中, 考察了崩解剂的用量以及崩解剂的添加方式对美索舒利薄膜衣片片芯 的影响, 具体如下:
按照表 7所示的配方以及实施例 1中的制备方法, 制备获得美索舒利片。
需要说明的是, 在本实施例中, 崩解剂的添加方式为两种: 内加法和外加法。
内加法是指在混合步骤中加入崩解剂, 外加法是指总混步骤中, 在加入润滑剂之前, 先将干颗粒和崩解剂混合均匀。
具体的, 当崩解剂进行内加法时, 与实施例 1中的添加方式相同;
当崩解剂进行内外加法时, 按表 7中的处方, 采用湿法制粒工艺, 分别制备样品, 制 备方法如下:
( 1 ) 原辅料前处理: 将主药 (美索舒利)、 各辅料分别粉碎后, 主药过 60目筛, 辅料 过 80目筛, 备用;
(2)配粘合剂: 称取 8克聚维酮 K30于烧杯中, 加纯化水 92克, 搅拌至澄清, 得 8% 聚维酮 K30水溶液 I, 备用;
(3 )混合: 称取处方量的主药、 处方量的填充剂混合均匀后, 再加入需內加的崩解剂 交联聚维酮混合均匀, 得混合物 II;
(4)制软材及制粒: 将处方量的粘合剂水溶液 I加入混合物 II中, 制成软材, 将所得 软材过 18目不锈钢筛制粒, 得湿颗粒;
( 5 ) 干燥: 将步骤 (4) 中所得到的药物湿颗粒于 60°C±5°C下干燥约 2h;
( 6) 整粒: 将经过干燥的药物颗粒过 18目不锈钢筛整粒, 得干颗粒;
(7 ) 总混: 干颗粒中加入处方量的需外加的崩解剂交联聚维酮, 再加入处方量硬脂酸 镁, 混合均匀, 得总混颗粒;
( 8 )压片: 根据总混颗粒所测得含药量, 计算理论片重, 将压片机调整到适宜的填充 量, 控制压力使薄膜衣片片芯硬度在 5〜7kg以内, 压片即得。
然后测定制备获得的美索舒利薄膜衣片片芯的硬度、 脆碎度、 崩解时间和溶出度, 测 定结果见表 7。其中,表 7所示处方 24-处方 28的配方为制备 1000片美索舒利片的处方量。
崩解剂的处方筛选
Figure imgf000014_0001
从表 7的结果可以看出, 处方 24、 处方 25和处方 26溶出度结果差异不大, 说明减少 一定量的崩解剂仍可以保持较好的溶出, 同时还可以节约成本。 处方 27和处方 28的崩解 剂均采用内外加法, 溶出度明显提高。 外加崩解剂可以促进颗粒的崩解, 内加崩解剂则能 加快颗粒的分散, 有利于提高溶出度。 从上述结果可以看出, 采用崩解剂内外加法的工艺, 相对于崩解剂只采用内加法的工艺, 其溶出度明显提高。 故确定崩解剂的用量及添加方式 为: 崩解剂的内加量为崩解剂处方量的 1/2, 外加量为崩解剂处方量的另 1/2。 因此, 暂定 处方为处方 28。 实施例 3: 制备工艺进一步优化实验
1、 对美索舒利原料药粒径考察
按照如下步骤考察美索舒利原料药的粒径对美索舒利片的影响, 具体如下: 以实施例 2中的处方 28为基础, 对本发明的制备工艺进一步优化, 以便进一步提高本 发明所述美索舒利薄膜衣片片芯的溶出度。
具体地, 按照处方 28, 分别制备两组 (A组和 B组) 美索舒利薄膜衣片片芯, 制备 A 组美索舒利薄膜衣片片芯的方法如下所述, B组美索舒利片剂的制备方法与 A组美索舒利 薄膜衣片片芯的制备方法区别在于, 主药美索舒利和辅料填充剂的混合物未进行微粉化处 理。 具体如下:
A组美索舒利薄膜衣片片芯的制备方法如下:
( 1 )原辅料前处理: 将主药(美索舒利)和填充剂微晶纤维素混合进行微粉化 (粒径 在 5微米至 100微米)、 其余各辅料分别粉碎后过 80目筛, 备用;
(2)配粘合剂: 称取 8克聚维酮 K30于烧杯中, 加纯化水 92克, 搅拌至澄清, 得 8% 聚维酮 K30水溶液 I, 备用;
(3 )混合: 将美索舒利和填充剂混合均匀后, 加入需內加的崩解剂交联聚维酮混合均 匀, 得混合物 II;
(4)制软材及制粒: 将处方量的粘合剂水溶液 I加入混合物 II中, 制成软材, 将所得 软材过 18目不锈钢筛制粒, 得湿颗粒;
(5) 干燥: 将步骤 (4) 中所得到的药物湿颗粒于 60°C±5°C下干燥约 2h;
(6) 整粒: 将经过干燥的药物颗粒过 18目不锈钢筛整粒, 得干颗粒;
(7) 总混: 干颗粒中加入处方量的需外加的崩解剂交联聚维酮, 再加入处方量硬脂酸 镁, 混合均匀, 得总混颗粒;
( 8)压片: 根据总混颗粒所测得含药量, 计算理论片重, 将压片机调整到适宜的填充 量, 控制压力使薄膜衣片片芯硬度在 5〜7kg以内, 压片即得。
然后测定制备获得的美索舒利薄膜衣片片芯的溶出度, 测定结果见表 8。
Figure imgf000015_0001
Figure imgf000015_0002
由表 8的结果可知, 相对于未经微粉化的美索舒利, 先将美索舒利和填充剂微晶纤维 素混合进行微粉化, 再制得的美索舒利薄膜衣片片芯的溶出度可以显著得到改善。 2、 压片工艺考察
根据生产条件, 结合片重及适宜片厚, 同时要考虑满足脆碎度要求, 采用压片机进行 压片。 将薄膜衣片片芯的硬度大小控制在表 9所示区间, 然后测定不同硬度的薄膜衣片片 芯的脆碎度、 溶出度和崩解时间, 测定结果见表 9。
表 9 考察硬度对实验结果的影响
Figure imgf000016_0001
从表 9的结果可知: 当薄膜衣片片芯的硬度在 4~7kg之间的范围时, 崩解时间和溶出 度受其影响不大; 而当硬度在 7~8kg时, 溶出度降低; 而当硬度在 4~5kg时, 脆碎度大; 考虑到薄膜衣片片芯还需要包衣, 对脆碎度的要求较高, 因此, 将薄膜衣片片芯的硬度控 制在 5~7kg为较理想的范围。
其中, 处方 30是规格为 50mg的美索舒利片, 其处方为: 美索舒利 50g, 微晶纤维素 170g, 聚维酮 K30 8g, 交联聚维酮 (内加 )6g, 交联聚维酮 (外加 )6g, 硬脂酸镁 2.5g。
处方 29是规格为 lOOmg的美索舒利片,其处方为: 美索舒利 100g, 微晶纤维素 120g, 聚维酮 K30 8g, 交联聚维酮 (内加 )6g, 交联聚维酮 (外加 )6g, 硬脂酸镁 2.5g。
制备方法如下:
( 1 )原辅料前处理: 将主药(美索舒利)和辅料填充剂混合进行微粉化(粒径在 5微 米至 100微米)、 其余各辅料分别粉碎后过 80目筛, 备用;
(2)配粘合剂: 称取 8克聚维酮 K30于烧杯中, 加纯化水 92克, 搅拌至澄清, 得 8% 聚维酮 K30水溶液 I, 备用;
(3 )混合: 将美索舒利和填充剂混合均匀后, 加入需內加的崩解剂交联聚维酮混合均 匀, 得混合物 II;
(4)制软材及制粒: 将处方量的粘合剂水溶液 I加入混合物 II中, 制成软材, 将所得 软材过 18目不锈钢筛制粒, 得湿颗粒;
(5) 干燥: 将步骤 (4) 中所得到的药物湿颗粒于 60°C±5°C下干燥约 2h; ( 6) 整粒: 将经过干燥的药物颗粒过 18目不锈钢筛整粒, 得干颗粒;
(7 ) 总混: 干颗粒中加入处方量的需外加的崩解剂交联聚维酮, 再加入处方量硬脂酸 镁, 混合均匀, 得总混颗粒;
( 8 )压片: 根据总混颗粒所测得含药量, 计算理论片重, 将压片机调整到适宜的填充 量, 分别控制压力使薄膜衣片片芯硬度在 4~5kg、 5~6kg、 6~7kg、 7~8kg以内进行压片即得 上述不同硬度的美索舒利片。
3、 包衣工艺研究
为了保证薄膜衣片质量和方便服用, 常在美索舒利片芯 (本发明中所述的片芯, 即是 指上述实施例中未进行包衣的美索舒利片) 表层包裹适宜的衣层材料, 使薄膜衣片中的药 物与外界隔离, 得到在美索舒利药物表面覆盖有薄膜衣的薄膜衣片, 从而达到防潮、 避光、 隔绝空气氧化、 增强药物保存的稳定性, 掩盖薄膜衣片中的不良嗅味和减少药物剌激的目 的。
( 1 ) 包衣材料为: 白色胃溶型欧巴代 81W68907, 上海卡乐康包衣技术有限公司生产。
(2) 包衣液配制
将包衣粉末加入到纯化水中, 配制成固含量 20%的溶液, 用螺旋式的搅拌桨搅拌 45分 钟即可。 制好的包衣液可以通过蠕动泵, 直接从配液容器中泵出使用。
( 3 ) 包衣条件
设定进风温度 85°C,平均片床温度为 41 °C,包衣锅转速 15~23r/min,喷浆速度 3~4g/min。 每片增重至设定值后, 停止喷包衣液, 吹冷风干燥, 待片温降至室温后出片, 用薄膜袋装 好, 称重, 取样检查。
(4) 包衣粉用量的筛选
取上述制备的 130804批美索舒利薄膜衣片片芯样品,按片芯重量的 5 %,称取包衣粉, 加纯化水制成固含量为 20%的溶液, 考察不同包衣增重的包衣效果, 考察结果见表 10。
表 10包衣粉用量的筛选
Figure imgf000017_0001
表 10的结果表明, 包衣粉用量为片芯重量的 3.0%以上时, 包衣片外观已能满足要求, 且随着包衣粉用量增加, 崩解时间相应延长, 当包衣粉用量为 4.0%时, 崩解时间存在加速 延长的可能。 对上述三种外观满足要求的包衣片进行基本性能评价如下表 11所示: 表 11 包衣片基本性能评价
Figure imgf000018_0001
结合表 10和表 11 的结果综合考虑, 选择包衣时将包衣增重控制在片芯重量的 3.0% -3.5%, 既能满足包衣片的外观要求, 又不影响崩解时间和溶出度, 还能起到较好的遮光效 果。

黄色 加速 6个月后, 四种包装的含量、 有关物质溶出度都无显著变化。 PVC泡罩包装和塑 料瓶包装的片子片重有明显增加, 提示这两种包装的片子都有不同程度的吸潮, 可能是因 为塑料瓶和 PVC泡罩包装的气密性差, 受湿度影响较大。 双面复合铝膜袋包装的虽然各个 指标变化不大, 但由于开封后不易保存, 所以不采用。 PVC 泡罩 +双面复合膜铝袋包装的 片子, 外观性状、 含量、 有关物质及溶出度都比较稳定。 可见 PVC泡罩 +双面复合铝膜袋 包装耐水蒸气渗透性、 密封性能良好, 能有效保证本品的长期稳定性。 因此, 选择 PVC泡 罩 +双面复合铝膜袋包装为美索舒利薄膜衣片的最优内包材。 在本发明的描述中, 需要理解的是, 术语 "第一"、 "第二"仅用于描述目的, 而不能 理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。 由此, 限定有 "第 一"、 "第二"的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中, "多个" 的含义是两个或两个以上, 除非另有明确具体的限定。
