一种含有环孢素的眼用药物组合物、其制备方法及用途 技术领域
本发明属于药物和制剂领域,涉及一种含有环孢素的眼用药物组合物、其制备方法及用途。
背景技术
环孢素为白色或类白色粉末,无臭。在甲醇、乙醇或乙腈中极易溶解,在醋酸乙酯中易溶,在丙酮或乙醚中溶解,在水中几乎不溶。环孢素的分子式为C 62H 111N 11O 12,分子量为1202.63,其结构式如下面的式A所示。

环孢素是一种新型强效免疫抑制剂,特点是高效低毒。它可以抑制T淋巴细胞和B淋巴细胞的增殖,并能选择性地影响免疫系统,实现对免疫系统的抑制。此外环孢素还具有抗炎症、抗感染、抗真菌和抗寄生虫等多种多样的生物生理活性。
环孢素是至今免疫抑制剂中作用最强、副作用最小的药物,它在免疫抑制剂中具有所不能取代的疗效和作用。另外环孢素可增加干眼症患者的泪液分泌,适用于因角膜、结膜炎症而引起的眼干燥症。
目前,市场上环孢素的制剂有很多,但由于环孢素是一个脂溶性极强的药物,所以一般是将其溶解在植物油中制成溶液剂。以油为溶媒的制剂通常存在许多缺点,尤其是对于眼局部使用,让人无法接受。
现有技术“环孢素A眼用微乳的制备及稳定性初步研究”以及专利CN103656617中虽然解决了环孢素制成眼用制剂眼刺激性大,不稳定的问题,但存在一定的杂质,并且使用舒适度有待于提高。
目前,尚需要开发新的环孢素眼用制剂。
发明内容
本发明人经过深入的研究和创造性的劳动,利用微乳剂型的技术,解决了上述问题,将难溶性药物环孢素制成稳定的眼用溶液制剂,溶液剂将更有利于药物的释放与吸收。本发明人还意外地发现,当药物组合物中的油相成分处于较低比例时(例如0.2%-0.9%),该组合物的杂质有显著下降的趋势,制剂更加稳定;特别是同时满足油相与表面活性剂的重量百分比含量的比例约为1:4时,效果更为明显。

结果显示:
实施例3以及实施例4各项指标与0月比较均无显著变化,证明该滴眼液处方合理、工艺稳定,能够稳定保存24个月;
虽然实施例5的有关物质也符合规定,但是与实施例3及实施例4相比,有关物质有显著上升趋势。说明当油相比例较低时,特别是处于0.2%-0.6%时,制剂稳定,杂质含量极低,符合规定;
对比例1的结果显示,当油相比例为0.1%时,乳剂系统不稳定,有破乳现象,因此油相比例应高于0.1%。
对比例2的结果显示,当油相比例为1.0%时,加速试验和长期稳定性试验杂质均超出限度,因此油相比例应低于1.0%。
实验例2:不同处方的环孢素滴眼液的稳定性试验
参照实验例1的实验方法进行,除了样品替换为实施例12处方工艺制备的样品。结果见下面的表3-4,其中实施例3制备的样品的数据采用前面实验例1中得到的数据。
