Description
技术领域
本发明属于药物制剂领域,具体涉及一种治疗肠易激综合征的药物组合物及其制备方法。
背景技术
肠易激综合征(irritable bowel syndrome,IBS)是一种持续或间歇发作,以腹痛、腹胀、排便习惯和(或)大便性状改变为临床表现,缺乏胃肠道结构和生化异常的肠道功能紊乱性疾病。罗马Ⅲ将其列为功能性肠病的一类,患者以中青年人为主,发病年龄多见于20~50岁,女性较男性多见,有家族聚集倾向,常与其他胃肠道功能紊乱性疾病如功能性消化不良并存伴发。在成人中肠易激综合征的患病率为10%~20%,目前能够有效治疗该疾病的药物还较少。
研究指出,5-羟色胺(5-HT)是胃肠道关键神经递质之一,5-羟色胺3(5-HT3)受体是开发肠易激综合征、类癌综合征、呕吐药物的重要靶点。申请号为CN200980119763.5的中国专利申请公开了一种式A所示的通式化合物,以及包括式B所示结构在内的多个具体化合物,该申请报道的这类化合物作为5-HT3受体的部分激动剂,可以引起患者5-HT3受体激活的净增加或净减少,能够用于治疗化学疗法引起的恶心和呕吐、手术后恶心和呕吐以及肠易激综合征等多种疾病。
但是,将上述化合物用于治疗上述疾病时,单次服用剂量很小(低至0.5mg/次),不利于准确控制给药剂量。如果用药剂量不准确,非常容易发生一些不良反应,不仅达不到好的治疗效果,相反会对患者身体造人成不必要的伤害。为了克服这个问题,人们尝试以该化合物作为活性成分,加入辅料制备成制剂。但是,在研究中发现,辅料的加入可能会降低该化合物的稳定性,导致杂质的增加。因此,开发出既能准确控制给药剂量,又能保持该化合物稳定性的制剂对该化合物的临床应用具有重要意义。

2.试验结果
表1 SMP-100及其混合物的稳定性测试结果
从表1中的稳定性试验数据可以看出,与试验第0天相比,样品3、6、7、10、11、14、15在25℃/92.5%RH、40℃/75%RH、60℃和光照条件下10天后SMP-100成分的含量均出现不同程度的降低,含量降低量大于2%,说明SMP-100与辅料甘露醇、无水磷酸氢钙、羟丙纤维素、羧甲淀粉钠、硬脂富马酸钠、明胶空心胶囊或欧巴代的组合得到的组合物稳定性较差,不利于制备成药物制剂。
从表1中的稳定性试验数据还可以看出,与试验第0天相比,样品2、4、5、8、9、12、13、16、17在25℃/92.5%RH、40℃/75%RH、60℃和光照条件下10天后的含量无明显变化,说明SMP-100与辅料乳糖一水合物、微晶纤维素、预胶化淀粉、羟丙甲纤维素、交联羧甲基纤维素钠、硬脂酸镁、胶态二氧化硅、交联聚维酮或低取代羟丙纤维素组合得到的组合物稳定性优良,这些辅料不会降低SMP-100的稳定性,可以用来制备SMP-100药物制剂。
试验例2、SMP-100药物制剂的稳定性测试
1.试验方法
待测样品:实施例1和对照例1制得的SMP-100药物素片。
测试方法:将上述素片分别在40℃/75%RH、60℃条件下放置30天,进行影响因素试验,观察/测试样品的性状、有关物质、溶出度、SMP-100成分的含量,结果如表2所示。
有关物质按照高效液相色谱法(中国药典2020年版四部通则0512)测定;
溶出度按照溶出度与释放度测定法(中国药典2020年版四部通则0931第二法)测定;
SMP-100成分的含量检测方法同试验例1。
2.试验结果
表2 SMP-100药物素片的稳定性测试结果
根据上述结果看出,相同条件下放置30天后,与对照例1制得的SMP-100药物素片相比,实施例1制得的SMP-100药物素片的总杂含量更低,SMP-100成分含量更高。此外,对照例1制得的SMP-100药物素片在40℃/75%RH条件下杂质明显增加,SMP-100成分的含量明显降低;但是,实施例1制得的SMP-100药物素片各项考察指标均无明显变化。
上述实验结果表明,本发明实施例1特定组成和配比的SMP-100药物制剂稳定性优异。
综上,本发明提供了一种治疗肠易激综合征的药物组合物及其制备方法。本发明首次发现,SMP-100与辅料乳糖一水合物、微晶纤维素、预胶化淀粉、羟丙甲纤维素、交联羧甲基纤维素钠、硬脂酸镁、胶态二氧化硅、交联聚维酮、低取代羟丙纤维素组合得到的组合物稳定性优异,适合制成药物制剂。本发明提供的药物组合物中辅料和SMP-100相容性好,所得制剂稳定性优异。而且,本发明药物组合物制备方法简单,易于实现工业化生产,应用前景广阔。
