本发明首次使用群孔释放的方式制备出具有择时释放功能的渗透 泵控释片, 是群孔释放技术和基础渗透泵控释片制备技术的结合, 意 想不到的是, 这两项技术的结合, 不但保留了原有技术的效果, 更重 要的是产生了延迟释放效果, 具有择时释放的作用。 由于本品的药物 释放具有与人体血压生理周期相配的时间间隔, 可以根据人体血压的 生理节律释放药物, 满足临床上时辰治疗的需要。 此外, 本发明还具 有以下效果:
简化了生产工序: 本产品的制备工艺不需要激光打孔, 简化了生 产工序有利于实现渗透泵控释片的产业化生产。
不需要新的设备投入: 本项目提供了一种无需进行激光打孔的择 时释放渗透泵控释片, 节省激光打孔设备的投入 1000万元人民币; 本 品在常规的片剂生产车间既可以生产, 不需要添置新的设备。
提高了药品的安全性: 由于采用群孔释放的方式, 避免了单一释 药孔容易被食物堵塞的风险, 不会方式释药孔被食物赌赛后片芯渗透 压无法释放, 导致控释膜爆裂, 药物突释, 大量的药物快速放出, 迅 速达到中毒浓度的问题, 大大提高了制剂的安全性。
减少了生产工序: 与激光打孔的基础渗透泵相比, 减少了激光打 孔工序和人工检查多打孔样品和漏打孔样品两个生产工序; 大大缩短 了生产周期、 降低人工成本和生产成本、 提高了成品率。
生产周期缩短: 激光打孔渗透泵控释片从投料到制成控释片需要
3天, 人工检查多打孔和漏打孔样品时, 每批样品以 50万片计, 需要 工人凭肉眼检查 7天时间,共需要 10天时间。本产品不需要激光打孔, 每批样品的生产时间缩短为 3 天, 大大缩短了生产周期, 降低了劳动 强度。
工艺重复性提高: 本项目的生产过程与基础渗透泵比较减少了 2 个生产工序, 与双层渗透泵控释片比较, 减少了 5 个生产工序, 生产 更加容易控制, 工业化生产可以很容易重复生产出质量稳定的产品。
成本降低: 由于不需要进行激光打孔和激光打孔设备的添置、 生 产车间的改造、 生产周期短等, 大大降低了电力消耗, 人力消耗等生 产过程的直接成本, 提高了工人单位时间的产出率, 工作效率大大提 高。 实施例

盐酸地尔 释放度的测定:
释放度测定方法: 按照释放度测定法(中国药典 2005年版二部附 录 XD第一法),采用溶出度测定法(中国药典 2005年版二部附录 XC ) 第一法的装置, 以水 900ml为释放介质, 转速为每分钟 100转, 在 4、 8、 12、 16、 和 24小时取样, 用紫外分光光度法在 236nm的波长处测 定样品与对照品的吸光度法,计算出不同时间的释放度。结果示于表 1。 表 1
Figure imgf000015_0001
上述释放度测定结果表明产生了延迟释放效果, 具有择时释放的 作用。
本发明发现, 致孔剂的含量和控释膜的包衣增重对盐酸地尔硫罩 的起始释放时间有显著影响。 在实施例 1片芯的基础上对 PEG6000在 控释膜中的比例和控释膜包衣增重对盐酸地尔硫 ¾的起始释放时间进 行了考察, 界定释放度小于 5%, 且后一个小时的释放度大于 5%的时 间点为起始释放时间点; 以包衣后控释片的平均重量减去片芯的平均 重量为包衣增重, 即, 控释膜重量, 以包衣增重相对片芯的重量比为 控释膜相对片芯的重量比例, 即, 控释膜占片芯的重量比例。 控释膜 的处方及释放结果示于表 2。 关于释放度的测定方法, 参见后述的释放 度测定方法。 表 2
Figure imgf000016_0001
结果表明, 致孔剂 (例如 PEG6000)占控释膜的重量比例在 19.5~ 29.8wt%的范围内、 控释膜占片芯的重量比例在 15.1~25.7wt%的范围 内, 可以控制起始释放的时间在 4 小时。 因此, 优选致孔剂重量占控 #膜的重量比例为 19-30wt%, 更优选 20-29wt%, 进一步优选 23-27wt %。 优选控释膜重量占片芯重量的 15-26wt%, 更优选 16-24wt%。
此外, 本发明还进一步发现, 渗透压活性物质的含量对释放有很 大影响。 试验设计及释放度测定结果示于表 3和表 4。 表 3
Figure imgf000017_0001
表 4
Figure imgf000017_0002
致孔剂 (例如 PEG6000 )在控释膜中的比例大于 25wt %时, 增加 渗透压活性物质(例如 NaCl ) 的含量, 释放加快; 在控释膜中致孔剂 (例如 PEG6000 ) 的含量小于 25wt %时, 增加渗透压活性物质 (例如 NaCl ) 的含量, 释放变慢。 产业实用性
本发明产生了延迟释放效果, 具有择时释放的作用。 由于本品的 药物释放具有与人体血压生理周期相配的时间间隔, 可以根据人体血 压的生理节律释放药物, 满足临床上时辰治疗的需要。 此外, 本发明 还具有以下效果: 提高了药品的安全性、 工艺重复性提高、 成本降低。
