Description
本发明的技术领域
本发明涉及制备粉末组合物的方法,所述粉末组合物包含紫松果菊属物种(Echinacea spp.)的亲脂性提取物、姜(Zingiber officinale)的亲脂性提取物和磷脂。
本发明还涉及可通过本发明的方法获得的粉末组合物和包含所述组合物的药物、营养保健和化妆美容制剂。
根据本发明的粉末组合物及其制剂可用于预防和/或治疗炎症和疼痛状态。
发明背景
当局部或全身施用时,紫松果菊属物种、优选狭叶松果菊(Echinaceaangustifolia)的那些亲脂性提取物;花椒属物种(Zanthoxylum spp.)、优选花椒(Zanthoxylum bungeanum)的那些亲脂性提取物;金纽扣属物种(Acmella spp.)、优选千日菊(Acmella oleracea)的那些亲脂性提取物具有抗炎活性。已经证明它们的药理活性可归因于异丁酰胺,CB1和CB2大麻素受体的配体(Alkylamides from Echinacea are a newclass of cannabinomimetics;Stefan Raduner等人;J.Biol.Chem.(2006),281(20),14192-14206.Identification of CB1/CB2Ligands from Zanthoxylum bungeanum;Katina S.S.Dossou等人;J.Nat.Prod.2013,76,2060-2064)。
姜的亲脂性提取物的主要活性成分由姜醇和姜烯酚组成。姜醇和姜烯酚是LPS(脂多糖)诱导的PGE2(前列腺素E2)产生的强效抑制剂和炎症部位的促炎细胞因子的脂氧化酶多效性下调剂。此外,姜醇和姜烯酚是有效的香草素受体(VR1)激动剂(Comparativeantioxidant and anti-inflammatory effects of[6]-gingerol,[8]-gingerol,[10]-gingerol and[6]-shogaol;Swarnalatha Dugasania等人;J.Ethnopharmacol.127(2010)515–520.Gingerols:a novel class of vanilloid receptor(VR1)agonists;VadimN.Dedov等人,Brit.J.Pharmacol.(2002)137,793-798.Echinacea alkylamides modulateTNF-a gene expression via cannabinoid receptor CB2 and multiple signaltransduction pathways;Juerg Gertscha等人;FEBS Letters 577(2004)563–569)。
已经描述了含有狭叶松果菊和姜的亲脂性提取物的制剂可用于减轻炎症和外周疼痛(EP 2 598 156 B1)和用于预防和治疗胃食管反流(EP 2 379 095B1)。
考虑到狭叶松果菊(或花椒属或金纽扣属)和姜的亲脂性提取物为油性物理状态,软明胶胶囊代表了理想的口服施用制剂。众所周知,溶解性差的活性成分(其被配制为用于软明胶胶囊的基于脂质的填充物)的全身吸收可以通过甘油三酯的消化过程来介导和增强。此外,作为软明胶胶囊的基于脂质的填充物施用的溶解性差的活性成分的口服生物利用度也可以通过肠淋巴系统转运至全身循环来增强。
另一方面,软明胶胶囊制剂的特征在于一些缺点,因为由于活性物质和明胶壳之间的相互作用,活性成分通常更容易受化学降解和剂型的物理不稳定性影响。这尤其在用于植物提取物时发生,原因是植物提取物的多组分化学组成。此外,软明胶胶囊的生产需要特定的设施和设备,其仅可从有限数量的公司获得。
因此,仍然需要供选择的组合物,其特征在于活性成分的高度和快速吸收,其能容易地掺入稳定的制剂中。
发明概述
本发明涉及制备粉末组合物的方法,其包括以下步骤:
a)将紫松果菊属物种的亲脂性提取物或含有烷基酰胺的植物亲脂性提取物与姜的亲脂性提取物分散在至少一种有机溶剂中,并进行混合直至获得溶液或混悬液;任选地加热;
b)然后将至少一种磷脂加入所述多个亲脂性提取物形成的溶液或混悬液中,并将该混合液进行混合;任选地加热;
c)然后除去有机溶剂,得到粉末组合物。
本发明还涉及可通过本发明的方法获得的粉末组合物以及包含所述组合物的药物、营养保健和化妆美容制剂。
根据本发明的粉末组合物可用于预防和/或治疗炎症和疼痛状态。
发明详述
令人惊讶地发现根据本发明所述的制备方法制备的粉末组合物,其包含紫松果菊属物种的亲脂性提取物(或含烷基酰胺的其他植物提取物)和姜的亲脂性提取物以及磷脂,可用于制备固体制剂,诸如除了软凝胶之外的常规剂型,如片剂和硬明胶胶囊,且与包含相同活性成分的机械混合物的软明胶胶囊制剂相比,所得的固体制剂保证了相似或改善(更高和/或更快)的活性成分的吸收,导致药理作用的快速起效。

制备根据本发明的粉末组合物的制备方法包括以下步骤:
a)将紫松果菊属物种的亲脂性提取物或包含烷基酰胺的植物亲脂性提取物与姜的亲脂性提取物分散在至少一种合适的有机溶剂中,并进行混合直至获得溶液或混悬液;如果需要,任选地加热;
b)然后将至少一种磷脂加入所述多个亲脂性提取物形成的溶液中,并将该混合液进行混合;任选地加热;
c)然后除去有机溶剂,得到粉末组合物。
紫松果菊属物种的亲脂性提取物优选从狭叶松果菊或紫松果菊(Echinaceapurpurea)、更优选从狭叶松果菊获得。
可使用含烷基酰胺的其他植物亲脂性提取物,此类提取物可以是,例如,花椒属物种或金纽扣属物种的亲脂性提取物。优选地,花椒属物种的亲脂性提取物可以从花椒、胡椒木(Zanthoxylum piperitum)、美洲花椒(Zanthoxylum americanum)获得,金纽扣属物种的亲脂性提取物从千日菊获得。
