Description

一种含有喹硫平的控 (缓) 释制剂及其制备方法和用途 技术领域
本发明涉及控 (缓) 释药物领域, 尤其涉及一种含有喹硫平的控 (缓) 释制剂及其制备方法和用途。 背景技术
喹硫平(Thiazep ine ) , 即 1 1- [4- [2 ( 2-羟基乙氧基) 乙基] -1 -哌嗪基] 二苯并 - [b,f] [ l,4]硫氮杂卓, 是一种非典型抗精神病药, 其为脑内多种神 经递质受体拮抗剂, 抗精神病机理可能主要通过阻断中枢多巴胺 D2受体和 5-HT受体。 对组胺 受体和肾上腺素 a i受体也有阻断作用, 国外临床已将 该药作为治疗精神分裂症的一线药物。
喹硫平普通制剂的药动学研究结果表明, 其口服快速吸收, 约 1. 0— 1. 8 小时血药浓度达峰值, 消除半衰期较短。 所以, 国内外临床治疗精神分裂症 时均采用每日给药 2— 3 次, 这导致患者体内血药浓度波动, 带来较大的副 作用。 因此, 提供一种治疗用持续释放的喹硫平缓 (控) 释剂型一直是本领 域的技术人员所追求的理想。
喹硫平缓释制剂 (商品名: Seroque l XR ) 由阿斯利康率先在国外上市, 其专利信息披露在 US5948437 和公开的中国专利 CN101360504A要求保护含 有 5— 50% (重量) 的羟丙甲基纤维素的缓释制剂。 CN101002737A 公开了一 种含有喹硫平和缓释骨架材料及附加剂的缓释制剂, 所述的缓释骨架材料包 括亲水凝胶骨架材料, 溶蚀性骨架材料, 水不溶性材料, 所述的溶蚀性骨架 材料为硬脂酸, 十六醇, 十八醇中的一种或一种以上的任意组合。 CN101091700A要求保护一种由喹硫平, 有机酸, 水溶性高分子材料, 肠溶材 料, 蜡类以及水不溶性高分子材料的缓 (控) 释制剂组合物, 其中采用肠溶 性材料作为功能性包衣材料, 阻止药物在胃液中溶出, 蜡类材料和水不溶性 高分子材料用于控制胃液或肠液中的药物溶出。 CN101005829A公开了一种含 有蜡状材料和有效量喹硫平及其盐的多种新剂型, 其中包括持续释放的剂 型。 CN101347413A公开了一种包含 pH依赖性溶解度缓释骨架材料的喹硫平 缓释制剂, 分为普通的单层缓释片和双层缓释片。 使用的 pH 依赖的骨架材 料, 其溶解受胃肠道 pH的影响, 由于不同个体间的胃肠道环境的差异较大, 尤其不同年龄的患者之间, 这必将导致制剂体内吸收的变异性; 以蜡类材料 为基础的缓释制剂由于其水不溶性的特性, 其制备工艺的复杂性也限制了该 类材料的使用。
因此, 本领域迫切需要提供一种新的含有喹硫平的控 (缓) 释制剂。 发明内容

( 3 ) 减少用药的总剂量, 以使最小的剂量达到最大的治疗疗效; (4 ) 药物 与适当载体制成控 (缓) 释给药系统后, 药物的吸收和分布主要由载体的性 质决定, 因此根据临床要求选择适当的载体材料, 不仅可以将药物输送到特 定靶器官, 还可以在一定程度上改善药物的理化性质和药理活性, 具有广阔 的临床应用前景。 下面结合具体实施例, 进一步阐述本发明。 应理解, 这些实施例仅用于 说明本发明而不用于限制本发明的范围。 下列实施例中未注明具体条件的实 验方法, 通常按照常规条件或按照制造厂商所建议的条件。 除非另外说明, 否则所有的百分数、 比率、 比例、 或份数按重量计。
本发明中的重量体积百分比中的单位是本领域技术人员所熟知的, 例如 是指在 100毫升的溶液中溶质的重量。
除非另行定义, 文中所使用的所有专业与科学用语与本领域熟练人员所 熟悉的意义相同。 此外, 任何与所记载内容相似或均等的方法及材料皆可应 用于本发明方法中。 文中所述的较佳实施方法与材料仅作示范之用。 本发明实施例中使用的聚氧乙烯来自美国陶氏化学公司开发上市的商 品名为 P0LY0X™的产品, 其型号特点如表 1所示。
本发明实施例中制剂的控 (缓) 释特性可以体外溶出方法进行评价, 参 照中国药典 2005 co年版二部附录 X D释放度测定第一法, 采用溶出度测定法 n
(附录 X C ) 第一法的装置, 转速每分钟 100转, 模仿缓控释制剂载胃肠道 运转状态, 首先以 0. IN HC1溶液(9→1000) 750ml为溶剂放置 2小时。 然后 向介质中添加 250ml 的 0. 2M磷酸钠缓冲液, 用 2mol/ml 的盐酸溶液或氢氧 化钠溶液调整 pH至 6. 8 ± 0. 05 ) , 依法操作。 不同时间点取样后, 于 254nm 处测定吸光度, 按照外标法计算不同时间的累积释放量。 实施例 1一 3
