Abstract
包含利福昔明和药学上可接受的载体的利福昔明固体分散体。包含所述利福昔明固体分散体的药物组合物。
Description
本申请是申请日为2010年10月27日、申请号为201080055482.0、发明名称为“利福昔明固体分散体”的发明专利申请的分案申请。
技术领域
本发明涉及利福昔明(rifaximin)固体分散体,其增加利福昔明的溶解度并改善胃肠利用度;以及涉及制备这种固体分散体的方法。本发明还涉及包含利福昔明固体分散体的药物组合物。
背景技术
抗生素利福昔明最初在意大利专利No.1154655中公开。Marchi等人的相关美国专利No.4341785公开了具有抗菌效用的咪唑-利福霉素衍生物,以及制备该化合物的相关方法。US No.4341 785专利还公开了抗菌药物组合物和用它抗菌治疗胃肠道(GIT)疾病的方法。
利福昔明是与利福霉素相关的基本上不可吸收、非全身性、半合成的抗生素。其抗菌谱包括大多数革兰氏阳性和革兰氏阴性菌、以及包括需氧菌和厌氧菌两者。在某些国家,利福昔明被批准用于治疗其病因部分或全部归因于革兰氏阳性及革兰氏阴性菌所致的急、慢性肠道感染疾病,以腹泻综合征、改变的肠道微生物菌群、夏季腹泻样发作、旅行者腹泻和小肠结肠炎、胃肠道手术中感染并发症的手术前和手术后预防以及高氨血症治疗作为辅助。
利福昔明实际上不溶于水,亦实质上不在胃肠道(GIT)中溶解。利福昔明的相对不溶性也导致其可以忽略的全身吸收。在口服时小于0.5%的药物被吸收进入血流。
已知利福昔明能有效治疗局限于肠道的感染,而其适用于治疗由侵袭性生物体引起的全身性感染却是未知的。通过增加利福昔明的溶解性,可显著降低剂量,从而增加患者的依从性。有必要开发增加其溶解性并改善胃肠利用度的利福昔明剂型。
Ghagare等人的WO 2010067072公开了一种增加利福昔明溶解性从而提高利福昔明在体内的生物利用度的利福昔明复合物。
我们制备了利福昔明固体分散体,其意外地增加了利福昔明的溶解性以及胃肠利用度。
发明内容

在另一个实施方式中,利福昔明固体分散体提高了利福昔明的溶解性和胃肠利用度。
另一个实施方式涉及制备利福昔明固体分散体的方法。
另一个实施方式涉及包含利福昔明固体分散体的药物组合物。
另一个实施方式涉及包含含有治疗有效量利福昔明的稳定的固体分散体的药物组合物,与可商购片剂中的等剂量利福昔明相比或与简单溶液(如水或生理盐水溶液)中的等剂量利福昔明相比,口服摄入时其提供更高的利福昔明溶解性和改善的胃肠道(GIT)利用度。
另一个实施方式涉及治疗和/或预防微生物感染的方法,包括将治疗有效量的利福昔明固体分散体给予需要的患者。
另一个实施方式涉及包含含有治疗有效量利福昔明的稳定的固体分散体的药物组合物,其以足以为患者提供有益效果的剂量、频率和持续时间以各种频率或每天一次给予发生旅行者腹泻、肝性脑病、传染性腹泻、憩室病,结肠前手术抗菌预防、肠易激综合征、炎性肠病、克罗恩病、艰难梭菌相关腹泻、小肠细菌过度生长、旅行者腹泻预防、痢疾、陷窝炎(pouchitis)、消化性溃疡病、手术预防和胃消化不良的患者。
又另一个实施方式涉及包含含有治疗有效量利福昔明的稳定的固体分散体的药物组合物,其与第二药物活性剂联合给药。
另一个实施方式涉及包含含有治疗有效量利福昔明的稳定的固体分散体的改进释放的药物组合物,其与第二药物活性剂联合给药。
发明详述
本发明涉及包含利福昔明和药学上可接受的载体的利福昔明固体分散体,其提高了利福昔明的溶解性和胃肠利用度;以及涉及制备这种固体分散体的方法。
本发明还涉及包含含有治疗有效量利福昔明的固体分散体的药物组合物,其增加了利福昔明的溶解性并改善胃肠利用度。
增加药物溶解性的技术包括化学修饰如前药或成盐;物理修饰如固体分散体、纳米晶体和纳米颗粒、共晶及加载于多孔结构结构上;改变溶剂组成如pH调节、助溶剂和润湿剂;载体系统如环糊精、包合配合物、脂质体、聚合物胶束、乳液、微乳液和两亲性聚合物、表面活性剂分散体、通过胶体磨或喷射磨的微粉化等等。
因为其简单、经济及有利性,固体分散技术常被证明是提高难溶性活性药物成分的溶出率的最常用技术。
固体分散体的优点是由于分散在亲水性载体中而增加润湿性;降低药物粒径且因此增加两相固体分散体的表面积;降低结晶度或产生无定形体系。
固体分散体可以存在于单相如置换或间隙晶体溶液或无定形溶液中;或者它可以是两相系统如低共熔物、结晶药物无定形载体或无定形药物和无定形载体分散体。固体溶液是当两种化合物在其分子水平上彼此分散时而得到的单相。
形成固体分散体的各种方法包括传统熔融冷却法、热相挤出法(hot stageextrusion)、熔体聚块法(melt agglomeration)、法、共沉淀法、溶剂蒸发法如真空干燥、热板干燥、低温下缓慢蒸发、旋转蒸发、喷雾干燥、冷冻干燥、旋转干燥和超临界流体干燥。

3.用旋转蒸发仪蒸发上述混合物;

与可商购片剂或剂型中的等剂量利福昔明相比较,或与简单溶液(如水或生理盐水溶液或模拟胃肠液或缓冲液)中的等剂量利福昔明相比较,口服摄入的利福昔明固体分散体提供更高的利福昔明溶解性并改善胃肠道(GIT)利用度。溶解性的增加大于30%。
另一个实施方式涉及旨在提高难溶性药物的溶解的各种筛选和分析方法及制剂。这些分析方法包括溶解研究、饱和溶解性研究、润湿性研究、渗透性研究、X射线衍射研究等。
溶解性研究表明,纯的利福昔明在pH 6.8的Tris磷酸盐缓冲液中和纯水中的溶解度分别是0.01mg/mL和小于10μg/mL,而采用利福昔明、泊洛沙姆188和聚维酮(1:1:2)制备的固体分散体在pH 6.8的Tris磷酸盐缓冲液中和纯水中的溶解度分别是0.23mg/mL和0.38mg/mL。同样,采用利福昔明和聚维酮(1:3)制备的固体分散体在pH 6.8的Tris磷酸盐缓冲液中和纯水中的溶解度分别是0.35mg/mL和0.38mg/mL。因此,利福昔明固体分散体的溶解性的增加导致胃肠利用度的提高,而通过细胞渗透性研究证明全身吸收没有增加。
用MDCK细胞(Mardin Darby犬肾细胞)进行的利福昔明和利福昔明固体分散体的渗透性研究:
将最终浓度为10μ摩尔的利福昔明和利福昔明固体分散体置于培养有MDCK细胞的transwell板的顶侧。每个样品用于三个孔。在37℃下将板在振摇的水浴中放置2小时。在0和180分钟时从顶侧取20μl和从基底外侧取100μl进行样品处理。荧光黄用作标志物来观察细胞单层的完整性。Propronalol用作渗透性标志物。
发现通过荧光黄校正的MDCK细胞的完整性是适合的。甚至在2小时后顶侧相对面积仍然为100%。Transwell的基底外侧没有发现可检测量的利福昔明,从而反映出没有明显的渗透性(因为基底值是0,我们不能通过方程计算PAPP)。
因为利福昔明是局部作用的抗生素,利福昔明的固体分散体及含有固体分散体的组合物是有利的;因此可以实现较高的肠内水平。此外,可以降低通常用于治疗各种病原性疾病的利福昔明剂量,因为利福昔明对各种生物体的最低抑制浓度(体外)比粪便中利福昔明的浓度低很多。健康志愿者口服给予400mg 14C-利福昔明后,大约97%的剂量在粪便中回收(几乎完全为未改变药物),且0.32%在尿液中回收。
最低抑制浓度(MIC)定义为完全抑制可见生长(细微的、肉眼可见的浑浊或单个菌落忽略不计)的利福昔明最低浓度。
表1:利福昔明对选择的肠病原体的MIC90
固体分散体形式的利福昔明的剂量可以降低,因为其溶解性增加。用定量方法(扩散技术)来评价利福昔明固体分散体相对于纯利福昔明的抗菌效果。区域直径的测量估算细菌对抗菌化合物的易感性。
用平皿(cup plate)法或孔板法测定利福昔明和利福昔明固体分散体的抗微生物活性:
制备蒸馏水中的营养琼脂培养基,并且该培养基在高压灭菌锅中在121℃下灭菌15分钟。将该培养基在无菌条件下转移到无菌陪替氏平板中,使培养基固化数分钟。固化后,在各平板中加入测试微生物即大肠杆菌(100μl),并在涂布机的帮助下涂布该培养物。在钻孔器的帮助下在平板中制孔。在无菌条件下在各孔内加入测试样品(利福昔明和利福昔明固体分散体)200μl;在37℃下在培养器温育该平板24小时,然后观察孔周围的抑制圈。
24小时后,利福昔明显示几乎可忽略的抑制圈区域,而利福昔明与聚维酮(1:3)的固体分散体及利福昔明与泊洛沙姆和聚维酮(1:1:2)的固体分散体分别显示15mm和10mm的抑制圈区域。
本发明的利福昔明固体分散体可和药学上可接受的赋形剂一起配制成固体、半固体或液体制剂,配制成片剂(单层片剂、多层片剂、微型片剂、生物粘附片剂、囊片剂、骨架片剂、片中片剂、粘膜粘附片剂、改进释放片剂、脉冲释放片剂、定时缓释片剂、延迟释放片剂、控释片剂、延长释放片剂和持续释放片剂)、微丸、小珠、颗粒、持续释放组合物、丸剂、锭片、硬胶囊、软胶囊或液体填充的软明胶胶囊、微胶囊、微型片、胶囊和微球中的片剂、骨架组合物、渗透性组合物、生物粘附组合物、悬浮的粉末/微丸/颗粒、粉末、溶液、混悬剂、扁囊剂或乳剂等。

另一个实施方式涉及用于口服使用的含有利福昔明固体分散体的改进释放药物组合物。
另一个实施方式涉及含有利福昔明固体分散体的立即释放组合物和含有利福昔明固体分散体的改进释放组合物的各种组合。
含有利福昔明固体分散体的药物剂型可以任选具有一种或多种包衣,如薄膜包衣、糖衣、肠溶包衣、生物粘附包衣以及本领域已知的其它包衣。这些包衣使药物组合物在所需的作用位点释放药物。在一个实施例中,额外的包衣阻止剂型接触口腔或食道。在另一个实施例中,额外的包衣保持剂型完整直到到达小肠(例如肠溶包衣)。可以用亲水性聚合物(如HPMC或明胶)层或包衣阻止生物粘附层的过早暴露或药物剂型在口腔中溶解。任选地,Eudragit FS 30D或其他合适的聚合物或试剂可加入包衣组成中以延缓药物释放,从而确保药物在结肠中释放。
