Description

一种稳定的晶 I型阿戈美拉汀片剂及其制备方法 技术领域
本发明属于药物制剂技术领域,涉及一种稳定的晶 I型阿戈美拉汀片剂及其制备方 法。
技术背景
阿戈美拉汀一褪黑激素类精神疾病类药物。 褪黑素类似物阿戈美拉汀
(agomelatine ),既是首个褪黑素受体激动剂,也是 5-羟色胺 2C (5- HT2C)受体拮抗剂。 动物试验与临床研究表明该药有抗抑郁、 抗焦虑、 调整睡眠节律及调节生物钟作用,同 时其不良反应少, 对性功能无不良影响, 也未见撤药反应。
首个褪黑素受体激动剂 agomelatine (Valdoxan)为褪黑素类似物,它同时也是 5一 羟色胺 2C (5- HT2C)受体拮抗剂。 褪黑素与其受体 MT1和 MT2的亲和力 Ki分别为 8. 85x10 及 2. 63x10—", 阿戈美拉汀与其相似,对克隆的人褪黑素受体 ΜΠ和 MT2也有 高度的亲和力(Ki分别为 6. 15x10— 11及 2. 68Χ1(Τ)。 临床研究表明, 阿戈美拉汀对抑郁 症患者有较好的疗效, 且不良反应非常少。
阿戈美拉汀抗抑郁的确切机制目前尚未明确。 单纯的 5- HT2C受体阻断剂并无抗抑 郁作用。 阿戈美拉汀能阻断 5- HT2C受体, 然而动物试验显示褪黑素也有少量的抗抑郁 作用,并有研究发现应激与褪黑素分泌有关,但人体服用褪黑素并未见明显的抗抑郁作 用。
另有研究表明,阿戈美拉汀抗抑郁的机制可能与增加海马部位神经元的可塑性及神 经元增生有关。 以免疫染色的方法测定成年大鼠脑部神经细胞的增生、 再生及死亡,结 果发现, 阿戈美拉汀长期 (3周)给药可增加海马腹侧齿状回细胞增生及神经元再生,而 这一部位与情绪反映有关。 但在急性或亚急性给药时 (4小时或 9周)未见类似情况。继 续延长给药后,整个齿状回区域均出现细胞增生及神经元再生,表明阿戈美拉汀可不同 程度地增加海马的祌经再生, 从而产生新的颗粒细胞。
阿戈美拉汀由 Servier公司开发研制, 目前已上市销售。 化学结构: CH
Figure imgf000003_0001
目前已发现了阿戈美拉汀 I、 ii、 m、 ιν、 v、 χ等多种晶型。 阿戈美拉汀片剂为 临床上常用的剂型, 但在晶 I型的阿戈美拉汀片剂制备过程中存在如下的难点:
( 1 )晶工型阿戈美拉汀原料药, 对粉碎、 研磨、 压力、 热等敏感, 均有不同程度的 转变为 II型结晶。 以下是晶 I型原料粉碎、 研磨、 压片 (10kg压力)通过 DSC测定其 变化(见附图广 4) 。
Figure imgf000003_0002
结果表明: 晶 I型阿戈美拉汀原料在粉碎、研磨、压片的过程中晶型有明显的变化, 转化为 II型结晶。
(2)辅料选择面窄: 像常用辅料微晶纤维素、预胶化淀粉等均不可用, 主要原因在 于, 上述辅料能加速阿戈美拉汀晶型的转变; 转化为 Π型。 因此, 采用常规制粒压片 工艺均不能保证晶 I型稳定。原料和辅料直接压片或干法制粒压片, 晶型立即会发生转 变; 用普通湿法制粒工艺, 转变更为明显。
另外, 法国瑟维尔实验室的专利申请 CN200510071611. 6 , 其中关于晶 II型的合成 工艺及药物组合 在 2007年获得中国专利授权,其晶 II型阿戈美拉汀得到保护。中国 专利 CN101704763A介绍了晶 I型制备方法。通过此方法制备得到的晶 I型阿戈美拉汀, 在实际的片剂制备过程中晶 I型极易转化成 II型, 进一步稳定性试验也存在进一步转 化为 II型的可能 (我们制备的样品片剂在加速 2个月后经粉末衍射检查: 原料药几乎 全部转化为 II型) 。 晶型的变化, 一方面可能造成侵权, 另一方面可能进一步带来药 物在生物利用度上的不一致。因此,解决晶型在片剂制备过程及保存中的稳定性是非常 说 明 书
重要的。

本发明所述的药用辅料为乳糖、 交联羧甲基纤维素钠、 交联聚乙烯吡咯垸酮、 硬 脂酸、 硬脂酸镁或二氧化硅。

本发明重点考察了如下的关键问题-
( 1 ) 溶剂选择- 晶 I型阿戈美拉汀几乎不溶于水, 在甲醇、 乙醇、 乙腈、 DMS0等中易溶, 进一步 带来晶型的变化。 因此, 选择在水中制备最佳, 最佳比例加入量约为原料的 0. 5- 4倍;
(2 ) 药用辅料的选择:
晶 I型阿戈美拉汀对热与压力较为敏感, 在高温和高压条件下不稳定。
为此, 本发明人考察了乳糖、 甘露醇、 磷酸氢钙、 微晶纤维素、 预胶化淀粉、 聚乙 二醇 4000、 聚乙烯吡咯烷酮 k30、 羟丙甲基纤维素、 羟丙基纤维素、 羧甲基淀粉钠、交 联羧甲基纤维素钠、 交联聚乙烯吡咯垸酮、硬脂酸镁、硬脂酸、 二氧化硅、滑石粉等辅 料与晶 I型阿: ^拉汀混合 (1 : 1 );晶 I型阿 ¾ ^拉汀原料同时在高温 60°C、高湿 RH92. 5%、 光照 4500±500Lx照度下放置 15天后,采用 DSC测定其晶型变化。
结果: 预胶化淀粉对测定干扰, 其中微晶纤维素有明显的晶型转变促进作用。 结合 上市品使用的辅料,我们选用乳糖、聚乙烯吡咯垸酮、羟丙甲基纤维素、羟丙基纤维素、 交联羧甲基纤维素钠、交联聚乙烯吡咯垸酮、硬脂酸、硬脂酸镁、 二氧化硅等作为试验 用的辅料。
( 3)保护剂的选择:
