Abstract
本发明的主题是一种口服药物组合物,该组合物包括用已知方法制成的二氯苯胺苯乙酸(或其药物学上可接受的盐,特别是钠盐)的γ-环糊精复合物,通过该组合物可显著降低二氯苯胺苯乙酸的胃肠道刺激作用,并同时提高生物利用度。
Description
二氯苯胺苯乙酸(diclofenac)钠(其化学名称为2-[(2,6-二氯苯基)氨基]苯乙酸钠盐)是一种有效并在许多国家中广泛使用的非甾体抗炎药,其商品名为Voltaren(Ciba Geigy)。
二氯苯胺苯乙酸以不同的剂型施用,例如片剂、膜衣片剂、锭剂、胶囊剂、缓释制剂、注射剂、栓剂、眼用溶液剂、凝胶。
与其他溶解性差且吸收缓慢的非甾体抗炎药类似,最常使用的片剂剂型在胃中产生局部刺激作用,尤其是在长期治疗的情况下。
环糊精是由6、7或8个α-D-吡喃葡萄糖单元组成的环状寡糖,其中的葡萄糖单元是通过α,1→4键连接在一起的。8元环称为γ-环糊精。环糊精与合适尺寸的疏水性客体分子形成包含复合物。环糊精、环糊精衍生物、包含复合物的形成方法和复合物的特征已被Szejtli(环糊精及其包含复合物(Cyclodextrins and Their InclusionComplexes),Akademiai kiado,Budapest,1982,Cyclodextrin Technology,Kluwer Academic Publishers,Dordrecht,1988)和Fromming及Szejtli(药学中的环糊精(Cyclodextrins in Pharmacy),Kluwer Academic Publishers,Dordrecht/Boston,1994)广泛讨论。
二氯苯胺苯乙酸与其他非甾体抗炎药类似,也有毒副作用:它刺激胃肠粘膜,可发展成出血、溃疡和穿孔。溃疡的发展是一个复杂的过程,并涉及多个因素:粘膜屏蔽的损坏、粘膜类前列腺素合成的抑制、对细胞酶的直接作用、酸分泌增加、修复过程减慢等。给药剂量、给药途径、代谢等也起到一定的作用。药物的不同,某些因素的作用也发生变化。
二氯苯胺苯乙酸/环糊精复合物的制备和药物学应用已在几个专利中被描述过。

日本Kokai 87,138,437(Nakanishi,M.,1987)描述了包含甾体和非甾体抗炎药如二氯苯胺苯乙酸以及环糊精的栓剂。环糊精用作吸收促进剂。

该技术减少了药物结晶性。药物例如可以是二氯苯胺苯乙酸,而载体可以是环糊精聚合物或者水溶性环糊精。
EP 446753(Vectorpharma International S.p.A.,1990)涉及控制药物释放的治疗药物组合物。该药物的载体是交联聚合物基体,该基体不溶于水但在水中溶涨。
药物可以是如二氯苯胺苯乙酸,而聚合物基体例如是非水溶性的环糊精聚合物。
WO 92/00725专利申请(Farcon AG,1990)描述了如二氯苯胺苯乙酸的非甾体抗炎药的口服局部液体药物组合物。其建议组合药物和环糊精或者环糊精衍生物(物理混合物、复合物、共沉淀物)。环糊精可以是α-、β-、γ-环糊精或者羟丙基-β-环糊精。
EP 510561专利(Poli Industria Chimica S.p.A.,1991)的目的是泡沫形式的口服、经皮和阴道内给药的液体药物组合物。药物有许多,可以是二氯苯胺苯乙酸,或者其环糊精复合物。

Takeda Chemical Industries,Ltd.的专利(EP 519428,1992)描述了一种包含环糊精和水溶性差的药物如二氯苯胺苯乙酸的药物组合物。该组合物包括水溶性有机溶剂,特别是在注射液时。
WO 94/28936专利申请(Ciba-Geigy,1993)涉及一种新型的制备口服固体剂型的方法,所述固体剂型包括二氯苯胺苯乙酸(或其盐)。该剂型是通过直接压制二氯苯胺苯乙酸或其盐的环糊精包含复合物来得到的。其实施例描述了1∶1摩尔比的复合物。

EP 658347专利描述了制备注射药物或兽用组合物的方法(SouthAfrican Druggist Ltd.,1993),该组合物包括二氯苯胺苯乙酸(或其盐)和2-羟丙基-β-环糊精。该注射组合物用于抑制前列腺素合成。该组合物可包括药物和环糊精的包含复合物或混合物。在人自愿者上进行的药代动力学研究表明用环糊精制成的制剂在肌内注射时与市售的二氯苯胺苯乙酸钠注射液是生物等效的,但是如果注射液包含环糊精,可在更短的时间内达到更高的血浆浓度。
WO 95/32737专利申请(South African Druggist Ltd.,1994)描述了制备固体药物组合物的方法,该组合物包含β-环糊精或其衍生物(羟丙基或甲基βCD)和水溶性差的非甾体抗炎药如二氯苯胺苯乙酸钠。该组合物是药物的包含复合物,其是通过捏合法、然后在40℃下干燥制得的。当溶解于水中时,固体产物形成澄清或略微浑浊的溶液,该溶液适合于口服使用。
所有这些发明和专利都描述了二氯苯胺苯乙酸与环糊精之包含复合物的制备方法,其方法早已广为人知并已广泛使用。它们的目的是实现药物的更快溶解和更高的溶解度,根据用药物的包含复合物进行的常规实验,希望该药物达到更快的生物吸收和更好的生物利用度。
涉及以上所述之二氯苯胺苯乙酸的发明、专利和其他出版物包括几种进一步的物理-化学研究结果,例如X-射线衍射研究二氯苯胺苯乙酸/环糊精复合物之晶体结构,用核磁共振、Fourier转换红外光谱、差示扫描量热法研究溶液中二氯苯胺苯乙酸与环糊精分子之间的相互作用。
上述发明和专利的绝大多数都是采用β-环糊精来复合二氯苯胺苯乙酸。在实施这些专利时,根据JECFA的推荐尚未知晓β-环糊精的每日口服剂量不应超过6mg/kg体重。也就是说,胃肠道吸收少部分的β-环糊精,并可导致肾脏不可逆的损伤。
因此,包含β-环糊精的口服二氯苯胺苯乙酸制剂是不适宜的,这是因为对于所有的经推荐用于口服使用的二氯苯胺苯乙酸/β-环糊精复合物,该6mg/kg的限值都已被大大地超出。
几个报道涉及二氯苯胺苯乙酸/环糊精包含复合物的制备和表征。(例如Backensfeld,T.,Mueller,B.W.:Arch.Pharm.,323,690,1990;Backensfeld,T.,Mueller,B.W.,Kolter,K.:Int.J.Pharm.,74(2-3),85,1991;Devi,S.G.,Prakasam,K.,Udapa,H.:Indian J.Pharm.Sci.,54(6),259,1992;Orienti,I.,Cavallari,C.,Zecchi,V.:Arch.Pharm.,322,207,1989;Orienti,I.,Fini,A.,Bertasi,V.,Zecchi,V.:Eur.J.Pharm.Biopharm.,37(2),110,1991;Singh,U.V.,Pandey,S.,Udupa,N.:Indian J.Pharm.,55(4),145,1993)。

本发明的具体实施方案涉及包括至少50重量%之上述包含化合物的化学组合物,其余量是二氯苯胺苯乙酸和/或由二氯苯胺苯乙酸与环糊精形成的包含化合物,该包含化合物不是二氯苯胺苯乙酸与γ-环糊精按1∶2摩尔比形成的包含化合物。
而且,本发明的具体实施方案涉及一种化学组合物,其中,其余量是二氯苯胺苯乙酸与γ-环糊精按约1∶1的摩尔比形成的包含化合物。
另外,本发明的具体实施方案涉及一种化学组合物,其中,所述组合物包括至少80重量%、优选至少90重量%、特别优选至少95重量%的由二氯苯胺苯乙酸与γ-环糊精按约1∶2的摩尔比形成的包含化合物。

11只鼠没有发现溃疡,在4只动物的胃中发现大于1mm的溃疡。最高的溃疡指数是13.5,平均值是1.7。在任何一只对照动物中都没有发现溃疡。
在二氯苯胺苯乙酸钠/γ-环糊精复合物处理的动物组中的溃疡数量明显地低于未复合之二氯苯胺苯乙酸钠处理组的。
因此,在以10mg/kg(二氯苯胺苯乙酸钠)单剂量给药时,γ-环糊精大大地降低了二氯苯胺苯乙酸钠的胃刺激性。实施例2
在鼠的亚急性实验中比较二氯苯胺苯乙酸钠/γ-环糊精复合物(“A”组合物)和未复合之二氯苯胺苯乙酸钠的胃肠刺激性。使用平均重量为220 g的雄性Wistar鼠。在实验前和实验期间,动物都保持标准的LATI率和鼠食物。如下以15mg/kg剂量的二氯苯胺苯乙酸钠(10只鼠)或者包含等量二氯苯胺苯乙酸钠的复合物(10只鼠)口服给药于动物4天:
第1天:15mg/kg在8a.m.
