Description
发明领域
本发明涉及易受酸影响的质子泵抑制剂化合物、例如含有咪唑基部分的取代亚硫酰基杂环化合物的碱性盐的改进的制备方法。特别是,本发明涉及奥美拉唑的碱性盐或(S)-奥美拉唑的碱性盐、优选这些化合物的镁盐的改进的制备方法。本发明还涉及药物制剂的改进和含有通过所要求保护的方法制备的化合物作为活性成分的产物以及该产物在药物中的应用。
发明背景和现有技术
取代的苯并咪唑例如通用名为奥美拉唑、兰索拉唑、泮托拉唑、雷贝拉唑和来明拉唑的化合物具有使该化合物适于用作胃酸分泌抑制剂的性质。已知该类化合物用作质子泵抑制剂或H+、K+-ATP酶抑制剂。有大量的专利和专利申请公开了这类质子泵抑制剂及其制备方法。
在工业上通常需要采用使所制备的产物具有某些性质的方法生产药物活性化合物,所述性质是例如易于在工业规模上进行操作,并在贮存过程中具有稳定性,使其适用于药物制剂。活性物质,即药物,还应当以具有适用于药物制备方法的物理化学性质的形式存在,并且药物应该以达到适于其预期的药学作用的速率从剂型中释放。通常,配制者关心的是开发具有所需性质的剂型。然而,为了获得好的制剂,活性物质本身的制备以及以最适当的形式存在是有益的和重要的。
WO 95/01977公开了具有特定结晶度的奥美拉唑镁盐使得所要求保护的产物特别适用于药物制剂;在WO 95/01783中也讨论了该问题。
在WO 97/41114中描述了奥美拉唑镁盐的有效制备方法。该方法包括将奥美拉唑与弱碱和镁源混合并进行反应,反应任意地在有机溶剂存在下进行。反应完成后,优选将产物从滤液中结晶。
在例如WO 94/27988中公开了有关质子泵抑制剂的碱性盐的其他制备方法,其中描述了奥美拉唑的单一对映体及其碱性盐的制备。
本发明提供了超过现有技术方法的改进方法。尤其典型的是WO97/41114中所述方法的改进。
在例如WO 96/01624中描述了适于质子泵抑制剂化合物的药物剂型。所述专利申请描述了含有活性物质的小肠溶衣包层的丸剂的制剂。将这些肠溶衣丸压制成片剂。优选的是如下对含有活性物质的小丸进行制剂:通过将活性物质喷雾涂层在种芯例如糖球上,然后施加肠溶衣层,在施加肠溶衣之前任选地先施加隔离层以使活性物质与最终施加的肠溶衣层隔离。
质子泵抑制剂化合物是易受酸影响的,并且从这些化合物的稳定性来看,显然必须对口服固体剂型进行保护以避免其与酸性胃液接触,并且活性药物必须被完整地运送到pH接近中性的胃肠道部分,在那里得以迅速吸收。
药物从药物剂型中的释放速度会影响该药物进入体循环中的整体吸收。已经对奥美拉唑和相关药物以及含有这些药物的剂型进行了研究(参见例如Pilbrant and Cederberg,Scand.J.Gastroenterology 1985;20(suppl.108)p.113-120)。这些药物的市场准入规定了对药物从药物剂型中释放的速度。
发明概述
本发明提供了含有咪唑基部分的取代亚硫酰基杂环化合物的碱性盐、特别是取代的苯并咪唑衍生物的镁盐的改进的制备方法。该方法得到大量的产物,该产物一经加水,得到pH值大于规定pH范围的悬浮液。所述产物适于进一步加工成药物制剂。含有这种新形式活性物质的该药物制剂的释放性质得以改善。所要求的方法尤其提供了一种更适宜的药物剂型例如多单位片剂用的大量药物产物。
根据改进的方法,制备含有咪唑基部分的取代亚硫酰基杂环化合物的碱性盐,并且该方法包括其中将碱加入洗涤溶剂中以调解溶液pH的最终步骤,该溶液用于产物的最终洗涤中。优选的是,按照WO97/41114的方法制备取代亚硫酰基杂环化合物的镁盐,作为参照,其中包括将取代亚硫酰基杂环化合物与弱碱优选胺或氨以及镁源例如有机或无机镁盐或该盐的组合物混合并进行反应。之后结晶并用碱性含水溶剂混合物洗涤分离的镁盐产物。
通过使用钙源或其他适宜的阳离子源,该方法还可用于制备其他含有咪唑基部分的取代亚硫酰基杂环化合物的盐,例如微溶或不溶性盐,优选多价盐如钙盐。微溶或不溶性盐的定义与欧洲药典(第3版)“General notice”条目下的定义一致。
本发明还提供了通过将活性物质喷雾涂层在种芯例如糖球上制备药物剂型的方法。活性物质优选易受酸影响的药物,选自含有咪唑基部分的取代亚硫酰基杂环化合物的碱性盐。将活性物质悬浮在大分子粘合剂的水溶液中。所得悬浮液的pH应当不显著低于纯药物饱和水溶液的pH。
在一个优选实施方案中,所要求的方法涉及含有取代苯并咪唑衍生物的镁盐的药物剂型的制备方法。尤其是,该方法涉及用在粘合剂水溶液中的奥美拉唑镁喷雾包层的球制剂。所制备的小丸用隔离层和肠溶衣层包衣,并填充到胶囊中,或者与片剂赋形剂混合压制成多单位剂型的片。优选的是,制备含有奥美拉唑镁的多单位肠溶衣包层片剂。
附图的简要说明
图1所示为奥美拉唑从实施例2制备的用奥美拉唑镁悬浮液喷雾包层的糖球中释放的速度。其中三个曲线是本发明制备的小丸,两个曲线是参照小丸。
发明详述
一方面,本发明提供微溶或不溶的式I所示含有咪唑基部分的取代亚硫酰基杂环的碱性盐的制备方法其中
苯并咪唑部分苯环内的N是指任选被R7-R10取代的一个碳原子可以变化为不带取代基的氮原子;
R1、R2和R3彼此相同或不同,选自氢、烷基、烷硫基、任选被氟取代的烷氧基、烷氧基烷氧基、二烷氨基、哌啶子基、吗啉代、卤素、苯基烷基和苯基烷氧基;
R4和R5彼此相同或不同,选自氢、烷基和芳烷基;
R6是氢、卤素、三氟甲基、烷基和烷氧基;
R7-R10彼此相同或不同,选自氢、烷基、烷氧基、卤素、卤代烷氧基、烷基羰基、烷氧羰基、噁唑基、三氟烷基,或者毗邻的R7-R10基团形成可以被进一步取代的环结构;
R11是氢或者与R3一起形成亚烷基链,并且
R12和R13彼此相同或不同,选自氢、卤素或烷基,
并且其中烷基、烷氧基及其一部分可以是支链或直链C1-C9-链或者包括环烷基,例如环烷基烷基,
该方法包括式I的取代亚硫酰基杂环与阳离子源在碱存在下反应的步骤。该方法的特征在于洗涤步骤,其中用碱性含水溶剂混合物洗涤所制备的取代亚硫酰基化合物的碱性盐。优选的碱性含水溶剂混合物包括例如氢氧化钠或氨,优选使用含有乙醇、氢氧化钠和水的溶剂混合物。所得到的大量药物物质在式I取代亚硫酰基杂环的水悬浮液中所具有的pH值等于或大于所制备的纯的取代亚硫酰基化合物的碱性盐饱和水溶液的pH值。
通常,本发明适用于制备微溶或不溶的含有咪唑基部分的取代亚硫酰基杂环的碱性盐。本发明以奥美拉唑镁盐为例进行说明。
优选的是,如WO 97/41114所述,在弱碱存在下,通过奥美拉唑与镁源反应制备奥美拉唑镁盐,结晶并用碱性含水溶剂混合物洗涤所分离的奥美拉唑镁盐。
本发明的一个目的是,确保当所制备的大量药物悬浮在水中时,其pH值不显著低于纯化合物饱和水溶液的pH值。优选的是,当奥美拉唑镁悬浮液为10%(w/w)大量物质的悬浮液时,其pH等于或大于9.5。为了获得适宜的pH值(在10%悬浮液中测量),加入少量的碱以增加洗涤溶液的pH,从而保持大量药物在水中的pH值不显著低于纯化合物饱和水溶液的pH值。例如,奥美拉唑镁的pKa为8.8,奥美拉唑镁饱和水溶液在室温的pH值理论上为约9.6。
加入到洗涤溶液中的适宜的非挥发性碱是氢氧化钠,其加入量不超过0.1%(w/w)固体奥美拉唑,优选不超过约0.02%。对于所要求的方法,氨是另一适宜的碱。
第二方面,本发明提供改进的药物剂型制备方法,该方面包括将悬浮在粘合剂水溶液中的活性物质喷雾涂层在种芯、优选糖球上。将在水中的活性物质悬浮液,优选浓度为10-50%(w/w),与粘合剂混合,并任选地湿法研磨。在于流化床上喷雾涂层在糖球上之前控制并调节悬浮液的pH值。在下面的实施例中,制备25%奥美拉唑镁悬浮液。通过加入碱,将悬浮液的pH值控制和/或调节至不显著低于纯奥美拉唑镁饱和水溶液的pH值。适宜的碱是例如氢氧化钠和氨,其加入量是使pH升至期望值所需的量。
奥美拉唑镁饱和水溶液的pH值理论上为9.6,奥美拉唑镁和粘合剂的水悬浮液pH应等于或大于9.4,优选等于或大于9.5。
本发明的一个目的是,确保当制备喷雾涂层悬浮液时,即当药物悬浮在粘合剂水溶液中时,其pH值不显著低于纯化合物饱和水溶液的pH值。
用于活性药物悬浮液的适宜的粘合剂是大分子试剂,例如纤维素,如羟丙基甲基纤维素、甲基纤维素、羟丙基纤维素和羧甲基纤维素钠、聚乙烯吡咯烷酮、明胶、糖、淀粉和其他具有粘合性质的可药用物质。这些粘合剂可以单独使用或者以混合物的形式使用。
此外,该悬浮液可以含有与一种或多种可药用赋形剂混合的碱性反应物质。除了粘合剂之外,所述赋形剂是例如崩解剂和/或表面活性成分。
对所制备的喷雾涂层单位包肠溶衣。任选地通过在识别肠溶包衣层之前,将所述单位包隔离层,以使肠溶包衣层与活性药物层隔离。
适用于种芯、肠溶包衣层以及任选的隔离层的材料和技术是本领域已知的。优选的材料和技术描述于例如W0 96/01624中,该专利引入本文作为参考。发明的应用
已知质子泵抑制剂适于通过在酸分泌途径的最终步骤控制胃酸分泌来抑制哺乳动物和人的胃酸分泌。因此,从通常的意义上讲,它们可用于预防和治疗与胃酸有关的哺乳动物和人的疾病,包括例如反流性食管炎、胃炎、十二指肠炎、胃溃疡和十二指肠溃疡。此外,它们可用于治疗其他希望产生胃酸抑制作用的胃肠道疾病,例如用于接受非甾类抗炎药(NSAID)治疗的患者、用于非溃疡性消化不良患者、用于具有胃-食管反流性疾病症状的患者、以及用于胃泌素瘤患者。它们还可用于处于重病特别护理状态的患者、急性上部胃肠道出血患者、术前和术后预防胃酸吸入以及预防和治疗应激性溃疡。再者,它们可以用于治疗牛皮癣以及治疗螺旋杆菌感染和与这些相关的疾病,以及用于治疗或预防哺乳动物、包括人的炎性疾病。
含有本发明制备的药物活性物质的所制备的剂型适于口服给药。剂量取决于所治疗疾病的性质和严重程度。剂量还可以根据个体患者的年龄、体重和反应进行改变。对儿童和肝病患者以及长期接受治疗的患者采用多少低于平均值的剂量通常是有益的。在其他疾病的治疗中则可以采用高于平均值的剂量。
优选的是,以例如1-500mg的剂量每天一次施用质子泵抑制剂。适宜的剂量包括例如约5-100mg物质,更优选5-80mg。该剂型可以与其他适宜的药物例如抗菌化合物、NSAID、动力刺激剂和/或抗酸剂一起给药。该剂型可以变换为多单位剂型的泡腾片。
通过下面的实施例对本发明作进一步描述和讨论。这些实施例并非用于限制本发明的范围,本发明的范围是由权利要求书所定义的。结果与讨论
该药物加工方法的益处在于,将大量药物活性物质悬浮在水中将会导致该悬浮液的pH不显著低于纯化合物的饱和水溶液的pH。例如,奥美拉唑镁悬浮液的pH应为约9.6。
通过描述从含有糖球的药物剂型中溶出速度的实施例1和参照实施例A说明本发明,所述糖球是用奥美拉唑镁水悬浮液喷雾涂层的。结果表明,在制备过程的洗涤步骤中pH明显低于纯奥美拉唑镁饱和水溶液的pH可以引起奥美拉唑镁从所制备小丸中溶出的速度下降(参照实施例A)。这些结果可以与含有下述小丸的制剂进行比较,所述小丸是由在大量药物制备过程的洗涤步骤中pH不明显低于纯奥美拉唑镁饱和水溶液pH的奥美拉唑镁制备的(实施例1)。使得从药物剂型中溶出速度降低的机理可能是由于少量非离子化和不溶形式的物质(此处是非盐形式的奥美拉唑)在干燥物质的表面共沉不明显低于纯奥美拉唑镁饱和水溶液的pH,那么这种非盐形式奥美拉唑可能的沉淀不会影响从药物剂型中的溶出速度。
此外,通过实施例2和参照实施例B说明本发明。使用USP溶出装置对所制备的小丸进行试验,奥美拉唑的释放速度是在pH 6.8的磷酸盐缓冲液中测定的;离子强度I=0.16;温度37℃;搅拌速度100rpm。然后通过分光光度测定法(302nm)测定奥美拉唑的释放,结果示于图1中。
附图表明通过调节pH至不明显低于纯化合物饱和水溶液的pH,可以增加奥美拉唑的释放。实施例1
