Abstract
本发明涉及一种用于配制油性物质的新方法,以及由其可获得的粉末和固体剂型。该方法包括喷雾干燥水包油乳液的步骤,所述水包油乳液包含辛烯基琥珀酸淀粉酯和麦芽糊精。
Description
本发明涉及一种用于配制油性物质的新方法,以及由其可获得的粉末和固体剂型。特别地,该方法使用包含特定含淀粉材料的水包油乳液的静电喷雾干燥。获得的粉末特别适合于制备固体剂型像片剂,并且尤其是口腔分散片剂。
背景技术
油溶性物质通常以被包埋在软胶囊中的油性组合物的形式递送。然而,这种技术具有昂贵、劳动密集的缺点并且需要专用设备以便得到令人满意的配制品和令人满意的方法二者。而且,这些配制品具有短的保质期。
相反地,由于干燥粉末混合物的较高的化学和物理稳定性,其与油相比具有更长的保质期。因此,好的替代方案将能够将油性物质配制成粉末(固体分散体)组合物的形式。而且,粉末是用于提高疏水性药物的溶解速率并因此提高其生物利用度的有效手段。
为此,最近已经提出了利用静电喷雾干燥技术以便将油性物质配制成粉末。与经典的喷雾干燥相比,这种技术具有在低温下进行从而避免热敏性物质的降解的优点。而且,静电喷雾干燥是在惰性气体下运行的,因此保护配制品免于氧化。
这是专利申请WO 2016/123224的主题,其描述了一种通过静电喷雾干燥配制油性物质的方法。WO 2016/123224提供了一种方法,该方法包括用壁材料的溶液或悬浮液乳化芯材料的步骤,并且然后通过静电喷雾干燥雾化此乳液,其中该乳液具有按重量计15%-50%的固体含量。该芯材料可以选自例如碳水化合物、蛋白质、树胶、脂质、蜡、食品级聚合物以及纤维素材料。
然而,WO 2016/123224的乳液仍然需要改进以便获得具有令人满意的特性的粉末。
发明目的
因此,本发明的目的是提供油性物质的改进的配制品。更具体地,本发明的目的是提供适用于固体剂型(像片剂、特别是口腔分散片剂)的油性物质的粉末。
发明内容
诸位发明人通过开发一种特别适合于通过静电喷雾干燥加工油溶性活性物质的新的乳液配方成功地改进了先前的配制品。该配制品包含两种不同的含淀粉材料,这两种材料是辛烯基琥珀酸淀粉酯和麦芽糊精、特别是衍生自富含直链淀粉的淀粉的麦芽糊精。
其获得的粉末是可直接压缩的,并且可以因此有利地用于片剂的制造。而且,其获得的粉末展现出极好的化学和物理稳定性(氧化、光稳定性、温度等)。
尽管专利申请WO 2016/123224给出了其中引用各种含淀粉材料的可以用作壁材料的潜在材料的清单,但WO 2016/123224既没有披露也没有建议将它们组合。更具体地,WO2016/123224既没有披露也没有建议将辛烯基琥珀酸淀粉酯与麦芽糊精、特别是富含直链淀粉的麦芽糊精组合。
不受任何理论的约束,诸位发明人认为根据本发明使用的两种含淀粉材料在水包油乳液中起的作用不同。与可能在水相与油相之间的界面处的辛烯基琥珀酸淀粉酯(充当表面-活性剂)相反,麦芽糊精是水相的一部分。
这为获得的粉末、特别是用于压片、并且更具体地为口腔分散片剂提供了有利的特性。
发明简要说明
因此,本发明首先涉及一种用于通过水包油乳液的静电喷雾干燥制备粉末的方法,其中所述水包油乳液包含辛烯基琥珀酸淀粉酯和麦芽糊精。本发明进一步涉及一种由本发明的方法可获得的粉末。本发明进一步涉及一种包含本发明的粉末的固体剂型。
具体实施方式
本发明的第一目的是一种用于通过水包油乳液的静电喷雾干燥制备粉末的方法,其中该水包油乳液包含辛烯基琥珀酸淀粉酯和麦芽糊精。
可用于本发明的辛烯基琥珀酸淀粉酯和麦芽糊精二者都是含淀粉材料。表述“含淀粉材料”经典地是指由淀粉获得的物质。要提醒的是,表述“淀粉”经典地是指通过本领域技术人员熟知的任何技术从任何合适的植物来源分离的淀粉。经分离的淀粉典型地含有不超过3%的杂质;所述百分比以杂质的干重相对于经分离的淀粉的总干重表示。这些杂质典型地包含蛋白质、胶体物质和纤维残余物。合适的植物来源包括例如豆类、谷类和块茎类。
可用于本发明的第一含淀粉材料是辛烯基琥珀酸淀粉酯。
此类辛烯基琥珀酸淀粉酯对于本领域技术人员是熟知的。它们特别并且有利地是食品级的辛烯基琥珀酸淀粉酯。此类辛烯基琥珀酸淀粉酯典型地是通过酯化、例如由含淀粉材料与辛烯基琥珀酸酐的反应可获得的。
优选地,可用于本发明的辛烯基琥珀酸淀粉酯是冷水可溶的。特别地,这意指在生淀粉中观察到的典型的不溶性颗粒结构在辛烯基琥珀酸淀粉酯中消失了。这可以例如通过使含淀粉材料经受所谓的蒸煮步骤来完成。这可以例如在酯化步骤之前,在生淀粉上进行。
优选地,可用于本发明的辛烯基琥珀酸淀粉酯被进一步部分水解。
优选地,可用于本发明的辛烯基琥珀酸淀粉酯衍生自包含多于50%的支链淀粉的淀粉,表示为相对于所述淀粉的总干重的干重。此支链淀粉含量可以经典地由本领域技术人员通过直链淀粉用于形成络合物所吸收的碘的电位分析来确定。优选地,可用于本发明的辛烯基琥珀酸淀粉酯衍生自展现出至少60%、还优选至少80%、还优选至少90%、还优选至少95%的支链淀粉含量的淀粉。
优选地,可用于本发明的辛烯基琥珀酸淀粉酯衍生自糯淀粉、甚至更优选衍生自糯玉米淀粉。
优选地,可用于本发明的辛烯基琥珀酸淀粉酯是辛烯基琥珀酸淀粉钠。
优选地,可用于本发明的辛烯基琥珀酸淀粉酯具有如通过格里芬方法确定的、在从8至16的范围内选择的亲水亲油平衡值(HLB)。它优选地是至少10、还优选在从12至16的范围内选择、还优选在从14至16的范围内选择、例如等于15。
优选地,可用于本发明的辛烯基琥珀酸淀粉酯具有在从50至300cps的范围内选择的布氏粘度;所述粘度是在包含相对于溶液总重量的24%干重的所述辛烯基琥珀酸淀粉酯的溶液上、在20℃下、使用SC4-18转子在60rpm下在20min之后测定的。还优选地,此粘度在从90至150cps的范围内选择。
可用于本发明的辛烯基琥珀酸淀粉酯可能经受除了之前经受的优选的改性之外的其他化学和/或物理改性,只要它不干扰所希望的特性、值得注意地在最终粉末的安全性和功效方面。然而,并且因为似乎其在本发明中不是必要的,本发明的辛烯基琥珀酸淀粉酯优选没有被进一步改性。
可用于本发明的第二含淀粉材料是麦芽糊精。提及调节状态,麦芽糊精具有1至20的右旋糖当量(DE)。优选地,可用于本发明的麦芽糊精具有在从5至20、优选从10至20、优选从15至20的范围内选择、例如等于17的DE。
麦芽糊精经典地是冷水可溶的。它们经典地是通过含淀粉糊的酶水解获得的。应该注意以下事实:麦芽糊精不同于焦糊精(也常简称为“糊精”),后者是通过热和化学试剂对淀粉粉末的作用获得的。结果是,值得注意地相对于糖苷键特征,含淀粉材料的分子结构是不同的。

在此试验中,诸位发明人使用静电喷雾干燥将维生素D3的油性组合物配制成粉末。
将在22℃下以1百万IU/g和50cps的粘度(波通仪器公司(Perten Instruments)的快速粘度分析仪)溶解于玉米油中的维生素D3掺入使用Linecaps和CO01的水包油乳液中。通过在大约4500rpm下高速均质化(使用IKA混合器)、接着通过高压均质化(丹佛斯公司(Danfuss))制备了维生素 CO01的稳定的水包油乳液。
乳液的配方和特征如下:
将得到的乳液通过静电喷雾喷嘴在25psi的雾化气压下雾化至干燥腔中。将静电喷嘴施加20千伏(kV)电荷以进行淀粉水合。在干燥腔内,以25scfm递送干燥气体(90℃)以帮助水蒸发。应用到此技术中的干燥气体是空气与氮气的混合物,以控制氧气水平在5%以下以便使氧化最小化。获得了212,000IU/g的维生素D3的粉末。
2.本发明的粉末的表征

更具体地,通过具有ζ电位的粒度分析仪(马尔文公司(Malvern))测量了初级颗粒的初级粒度分布、和平均粒径D3,2和D4,3。通过氦比重仪(AccuPyc 1330,美国麦克仪器公司(MicroMeritics,US))在25±2℃下一式三份地测定真密度。最终粉末的堆积密度通过将精确称重(约4g)的粉末添加到25mL刻度量筒中一式三份地测定。测量对应的体积以获得堆积密度。最终粉末的拍实密度是根据USP II方法使用自动拍实机(tapper)(Stav 2003,瑞士Stampfvolumeter公司)测定的。最终粉末的可流动性是通过计算卡尔指数确定的。
获得的结果在表1中呈现。

表2:
片剂索引号 | IN-10,000IU | IN-1,000IU | CP-商业1,000IU |
Fc(KN) | 11.3 | 9.8 | N/A |
Fe(N) | 86 | 111 | N/A |
相对湿度 | 28% | 27% | N/A |
硬度平均值 | 50.4 | 47.5 | N/A |
崩解 | 56秒 | 57秒 | 1分16秒 |
脆性 | 0.49 | 0.69 | 0.82 |
根据本发明的粉末展现出如通过其形成具有良好硬度的片剂的能力来证明的良好的压片能力。而且,其获得的片剂在低于60秒的短的时间段内崩解,这使得它们适用于速溶固体剂型、特别是用于口腔分散片剂。
