Abstract
本发明涉及包含地夸磷索的眼用组合物,并且更具体地涉及包含地夸磷索、聚山梨醇酯和右泛醇的眼用组合物。
Description
技术领域
本发明涉及包含地夸磷索的眼用组合物,并且更具体地涉及包含地夸磷索、聚山梨醇酯和右泛醇的眼用组合物。
背景
地夸磷索是P2Y2嘌呤受体激动剂,并用于治疗干眼综合征。作为包含这种地夸磷索作为活性成分的眼用溶液,是可商购的。一天施用六次含有浓度为3w/v%的地夸磷索钠的滴眼剂具有以下缺点:由于这种多次施用的要求,患者需要多次给予该药物。为了有效治疗,以适当的方案施用药物是重要的,但是市售产品每天需要多次施用,因此使得患者难以遵循施用次数。
此外,滴眼剂由于其特性而具有在眼球中停留时间短并且药物递送速率低的缺点。考虑到地夸磷索的作用机理,重要的是有效地分散在泪层的水和粘液层中。然而,由于强的亲水性,地夸磷索对泪层的脂质层具有低的渗透性,并因此显示出低的吸收速率和持续性。因此,有必要通过增加药物进入脂质层的渗透性来开发一种具有更高药物递送速率的新滴眼剂。

图2是显示实施例3和对比例1的地夸磷索的渗透性的图。
图3是显示实施例4和对比例2的地夸磷索的渗透性的图。
发明的最佳方式
在下文中,将通过示例性实施方案更详细地描述本发明。仅出于说明本发明的目的而提供这些示例性实施方案,并且因此对本领域技术人员显而易见的是,本发明的范围不限于此。
<实验例1>渗透性(1)
根据下表1中所示的组分和含量制备组合物。将地夸磷索钠、聚山梨醇酯20(仅实施例1)、聚山梨醇酯80(仅实施例2)、右泛醇(仅实施例1和2)、缓冲剂和氯化钠溶解于无菌的纯水中,然后通过0.2μm膜滤器过滤,以制备组合物。所制备的溶液的pH为约7.2±0.2,且渗透压为300±30mOsmol/kg。
[表1]
将制备的实施例1和2以及对比例1放入半透膜(Float A lyzer)中,并放入包含模拟泪液(STF)溶液的溶解测试仪(SOTAXTM)中,以便通过使用液相色谱法评估活性成分的释放量。在使用半透膜的释放特性的实验中,通常通过使用有机溶剂诸如乙醇、异丙醇等激活半透膜。然而,在实验例1中,在不激活半透膜的情况下观察释放特性,以便评估聚山梨醇酯和右泛醇的渗透性。
如图1所示,证实了含有聚山梨醇酯和右泛醇的实施例1和2具有高的地夸磷索渗透性。
<实验例2>渗透性(2)
根据下表2中所示的组分和含量制备组合物。将地夸磷索钠、聚山梨醇酯80(仅实施例3)、右泛醇(仅实施例3)、缓冲剂和氯化钠溶解于无菌的纯水中,然后通过0.2μm膜滤器过滤,以制备组合物。所制备的溶液的pH为约7.2±0.2,渗透压为300±30mOsmol/kg。
[表2]
对于制备的实施例3和对比例1,以与以上实验例1中相同的方式评估地夸磷索的释放特性。
如图2所示,可以看出含有聚山梨醇酯和右泛醇的实施例3中的地夸磷索的渗透性似乎是高的。
<实验例3>渗透性(3)
根据下表3中所示的组分和含量制备组合物。具体地,将聚乙烯醇、黄原胶和聚维酮在无菌的纯水中在高温(例如,60℃至70℃或更高)下水合,之后溶解聚乙二醇,然后进行高压灭菌,以便制备溶液。将地夸磷索钠、聚山梨醇酯20(仅实施例4)、右泛醇(仅实施例4)、缓冲剂和等渗剂溶解在无菌的纯水中,通过0.2μm膜滤器过滤,并与以上制备的溶液混合,以制备组合物。在这种情况下,所制备的溶液的pH为约7.2±0.2。
[表3]
将制备的实施例4和对比例2放入半透膜(Float A lyzer)中,并放入包含模拟泪液(STF)溶液的溶解测试仪(SOTAXTM)中,以便通过使用液相色谱法评估活性成分随时间的释放量。
如图3所示,证实了实施例4表现出优异的地夸磷索渗透性。
以上结果表明,聚山梨醇酯和右泛醇提高了地夸磷索的膜渗透性。从这些结果中,预期包含聚山梨醇酯和右泛醇的组合物进入泪层的渗透性高于不包含聚山梨醇酯和右泛醇的组合物的渗透性。
因此,可以看出本发明的组合物具有增强的地夸磷索渗透性。
尽管上文已经详细描述了本发明的特定部分,但对于本领域的技术人员明显的是,阐述这样的详细描述以仅说明示例性实施方案,而不应解释为限制本发明的范围。因此,应当理解,本发明的基本范围由所附权利要求及其等同物限定。
