【发明内容】
【发明要解决的技术课题】
但是,本发明人发现,在含有罗匹尼罗及其药学容许的盐的贴附剂中,对于仅使用专利文献3~5的包装袋,则发生贴附剂的着色、结晶析出等的问题。再者,本发明人发现这些的着色有由药物的分解而发生的可能性。
因此,本发明旨在提供防止储存时的结晶析出,同时抑制着色,还抑制罗匹尼罗及其药学容许的盐的分解的内包贴附剂的包装袋、及贴附剂的保存方法。
【解决课题的技术方案】
为了达成上述目的,本发明提供具备包装袋,和在该包装袋的内部收容的贴附剂的内包贴附剂的包装袋,其特征在于,贴附剂有:支持体;粘着剂层,其层积于该支持体的至少一面,并含有罗匹尼罗和/或其药学容许的盐;以及剥离膜,其包被该粘着剂层,包装袋的内部在4℃相对湿度维持在35%以上。
根据涉及的内包贴附剂的包装袋,防止储存时的结晶析出,同时抑制着色,还抑制罗匹尼罗的分解。
再有,在4℃的相对湿度是指,将在4℃的一定体积中的空气可具有的最大的水蒸气量(kg·m-3:饱和湿度)作为100时的,相对其的实际上含的水蒸气量(kg·m-3)的比例(%)。
上述包装袋优选具有脱氧设施。由此,罗匹尼罗的分解防止效果、及贴附剂的经时着色防止效果进一步升高。
上述包装袋由2个以上的层构成,包装袋的最内侧的层优选是由选自聚丙烯腈、聚乙烯、聚酯的1种树脂形成的密封剂层,另外,包装袋的最外侧的层更优选是由选自聚对苯二甲酸乙二酯、赛璐玢、二轴延伸聚丙烯的1种树脂形成的外层。
上述包装袋优选在上述密封剂层和上述外层之间再有由铝形成的屏障层。
上述粘着剂层优选含选自丙烯酸系粘着剂、橡胶系粘着剂、硅系粘着剂的至少1种粘着剂。
另外,本发明提供贴附剂的保存方法,其特征在于,将贴附剂收容于包装袋,所述贴附剂具有:支持体;粘着剂层,其层积于该支持体的至少一面,并含有罗匹尼罗和/或其药学容许的盐;剥离膜,其包被该粘着剂层;以及使该包装袋的内部在4℃的相对湿度维持在35%以上。
根据涉及的保存方法,防止储存时的结晶析出,同时抑制着色,还抑制罗匹尼罗的分解。
【发明效果】
根据本发明的内包贴附剂的包装袋、及贴附剂的保存方法,可抑制含于贴附剂的罗匹尼罗或其药学容许的盐的结晶析出,再者,可抑制药物的分解。因此,在贴附剂的制备后,使用前,通过将贴附剂收容在包装袋的内部,可维持含于贴附剂的药物含有量。从而,使用时,可经皮吸收充分的量的罗匹尼罗。
【附图说明】
【图1】示本发明的内包贴附剂的包装袋的适宜的实施方式的截面图。
【图2】示对于实施例及比较例的内包贴附剂的包装袋测定袋内的相对湿度的结果的坐标图。
【实施方式】
以下,参照附图详细地说明本发明的实施方式。
图1是示本发明的内包贴附剂的包装袋的适宜的实施方式的截面图。内包贴附剂的包装袋1有:包括互相对向配置的一对积层包材7a,7b的包装袋8,和收容于此包装袋8内部的空间的贴附剂10。另外,在图1所示的内包贴附剂的包装袋1中,在包装袋8内还收容作为脱氧设施的包装脱氧剂20。在有这样的构成的内包贴附剂的包装袋1中,如后述,在包装袋8内部的在4℃的相对湿度维持在35%以上。
包装上述的贴附剂10的包装袋8由互相对向配置的一对大致矩形的积层包材7a,7b构成。积层包材7a,7b是有大致矩形的膜状的积层体,有密封剂层2,屏障层4,和外层6从内侧依次积层的构成。另外,互相对向配置的积层包材7a,7b在这些的外缘部接合,由此周围经全周闭合。再有,积层包材7单元的外缘部的接合可通过热密封进行,或使用附着剂进行。
构成积层包材7a,7b的各层之中外层6的材质不特别限定,但可举例如,选自赛璐玢、纸、合成纸、二轴延伸聚丙烯(OPP)、聚酯(例如,聚对苯二甲酸乙二酯)、尼龙、聚氯化亚乙烯(PVDC)、聚乙烯基醇(PVA)等的树脂膜,就是在其中也优选使用聚对苯二甲酸乙二酯、赛璐玢、二轴延伸聚丙烯(OPP)。通过使外层6为这些的树脂,可物理保护成为袋的内侧的层,同时抑制腐蚀等的包装袋外面发生变性。
再有,外层6由材料互相不同的多个层构成也可,例如,层积赛璐玢构成的层和聚乙烯构成的层也可。
外层6的厚度优选在5μm~600μm的范围、更优选在5μm~500μm的范围形成。外层6的厚度小于5μm,则有刚度降低,物理强度降低,使用性、保护性降低的倾向。另外,外层6的厚度超过600μm而变厚,则刚度升高,且物理强度也升高,发生制备的收率降低的倾向、及制备成本升高的倾向。
屏障层4是,为了对于包装袋内部,确保从外部的非透过性而防止填充的内容物的挥散,及为了确保贴附剂的稳定性而层积。作为其材质,不特别限定,但可举例如,铝箔、乙烯乙烯基醇共聚物(EVOH)膜、在塑料膜的表面蒸着铝等的金属或氧化硅等的陶瓷的膜,优选使用铝箔。作为屏障层4,通过使用铝箔,可完全地阻断光线、水蒸气、氧。
密封剂层2是指用于将构成包装袋的积层包材通过热密封附着而形成包装袋的树脂层,优选是热可塑性树脂层。构成密封剂层2的材料不特别限定,但可举例如,低密度聚乙烯(LDPE)、直链状低密度聚乙烯(LLDPE)、乙烯乙烯基乙酸酯(EVA)、亚乙基甲基丙烯酸共聚物(EMAA)、聚酯、亚乙基丙烯酸共聚物(EAA)、无延伸聚丙烯(CPP)、聚烯烃系离聚物树脂、聚丙烯腈(PAN),优选使用聚丙烯腈、聚乙烯、聚酯。
密封剂层2由药剂浸透性高的材料构成时,有贴附剂储存中积层包材的层的界面剥离的现象(层间剥离)发生,由于通过使成为内面的层为聚丙烯腈、聚乙烯或聚酯,可防止贴附剂成分的浸透,不发生层间剥离的问题。特别是,使内面的层全部为聚丙烯腈、聚乙烯或聚酯,则可有效抑制药物的分解。即,含药物的贴附剂在收容到包装袋的内部之后,即便贴附剂在包装袋的内部动的情况等,也可防止药物的分解。
密封剂层2的厚度是对于附着积层包材单元充分的厚度即可,例如有10μm~50μm左右厚度则可。
对于构成上述的积层包材7a,7b的各层的积层加工(层压)方法不特别限定,使用挤出层压、干层压、热熔层压、湿层压。
贴附剂10有:大致矩形的支持体12,将此支持体12之一面大致全面积层的粘着剂层14,和包被粘着剂层14的,可从粘着剂层14的剥离的剥离膜16。
支持体12只要是可支持粘着剂层14的则不特别限制,但优选良好地维持药物的移行性且柔软性优良的,使用伸缩性或非伸缩性的,优选可将药物从粘着剂层有效放出的。具体而言,可适宜地使用例如,以聚对苯二甲酸乙二酯、聚乙烯、聚丙烯、聚丁二烯、乙烯醋酸乙烯酯共聚物、聚氯乙烯、聚酯、尼龙、聚氨基甲酸酯的合成树脂形成的,膜或片或这些的积层体、多孔质膜、发泡体、织布及不织布、或纸材作为支持体。
作为剥离膜16,可使用聚对苯二甲酸乙二酯或聚丙烯等的树脂膜、离型处理的纸等,特别适宜地使用由实施硅处理的聚对苯二甲酸乙二酯构成的膜。
粘着剂层14是由含有粘着剂、及,作为药物的罗匹尼罗或其药学容许的盐(以下,将这些合起来称为“罗匹尼罗化合物”)的粘着剂组合物构成的。

实施例1的贴附剂观察不到着色,实施例3的贴附剂在60℃保存而确认若干的着色。比较例1,4的贴附剂观察到明显的着色。
【贴附剂的药物结晶析出的评价方法】
将实施例及比较例的内包贴附剂的包装袋于4℃储存30天,通过上述的方法测定湿度,通过目视或显微镜观察,贴附剂之一部分或全面析出放射状的针状结晶的情况评价为“有”结晶析出,无变化的评价为“无”结晶析出。其结果示于表4。
【表4】(贴附剂的药物结晶析出的评价结果)
样品(保存条件) | 湿度(相对湿度%) | 结晶析出 |
实施例1(4℃-30天) | 41以上 | 无 |
实施例2(4℃-30天) | 41以上 | 无 |
实施例3(4℃-30天) | 41以上 | 无 |
比较例1(4℃-30天) | 30以上 | 有 |
比较例2(4℃-30天) | 30以上 | 有 |
比较例3(4℃-30天) | 30以上 | 有 |
比较例4(4℃-30天) | n.d. | 有 |
n.d.:检测不到
【药物及分解物的生成的评价方法】
将实施例及比较例的内包贴附剂的包装袋在表5所示的保存条件下保存之后,将贴附剂从包装袋取出。将含于此贴附剂的成分用四氢呋喃10mL、水/甲醇混合溶液40mL提取而作为待检液,通过高效液相层析(ODS柱、UV检测器)检索罗匹尼罗及各未确认化合物。
各未确认化合物的量,以罗匹尼罗的理论量作为100,由各化合物的层析的吸收面积算出。再有,未检测到未确认化合物时以“-”表示。
【表5】(药物及未确认化合物的定量结果)
其结果,如表5所示,对于实施例及比较例的贴附剂在保持时间26.9分钟确认主分解物,但与比较例比较,则实施例的分解物的量极少,罗匹尼罗的含有量也维持得高。
【工业实用性】
根据本发明的内包贴附剂的包装袋、及贴附剂的保存方法,可抑制结晶析出,可提供药物的保存稳定性优良的医疗用贴附剂,产业上有用。
【符号的说明】
1...内包贴附剂的包装袋、2...密封剂层、4...屏障层、6...外层、7,7a,7b...积层包材、8...包装袋、10...贴附剂、12...支持体、14...粘着剂层、16...剥离膜、20...包装脱氧剂、22...脱氧剂、24...脱氧剂用包装袋。
