Abstract
本發明係一種貼附劑,其係具備支持體,以及配置於該支持體之至少一面上,且由含有藥物以及黏著劑之黏著劑組成物所構成之黏著層,其中前述藥物係金雀花鹼或其鹽,前述黏著劑組成物係酸價為10以下。
Description
本發明係有關貼附劑。
金雀花鹼(cytisine)係可與尼古丁乙醯膽鹼受體中的α4β2次單元(subunit)以高親和性進行結合之部份活化劑(partial agonist)。先前,金雀花鹼係舊社會主義經濟國家使用於戒煙目的。方式係將金雀花鹼製作為錠劑每日投藥6次(例如參照非專利文件1)。
非專利文件1:The New England Journal of Medicine, 2011, Vol. 365, p. 1193-1200
由於金雀花鹼錠劑需要每日經口投藥6次,於患者遵循醫囑方面,並非反應良好的藥物。
因此,以提供具有自黏著層釋出金雀花鹼之優異的釋出性,且可減少金雀花鹼每日投藥次數之貼附劑為目的。
本發明係提供一種貼附劑,其係具備支持體,以及配置於該支持體之至少一面上,且由含有藥物以及黏著劑之黏著劑組成物所構成之黏著層,前述藥物係金雀花鹼或其鹽,前述黏著劑組成物係酸價為10以下。
本發明之貼附劑,不僅具有自黏著層釋出金雀花鹼之優異的性質(釋出性),黏著層中之金雀花鹼亦具有優異的安定性以及金雀花鹼的皮膚通透性。因此,可降低金雀花鹼的每日投藥次數,並可提高患者的遵循醫囑性。
本發明之貼附劑,黏著劑亦可為丙烯酸系黏著劑。黏著劑為丙烯酸系黏著劑時,可提高自黏著層中金雀花鹼之釋出性以及金雀花鹼的皮膚通透性。即使丙烯酸系黏著劑中,當使用含有氫氧基之丙烯酸系黏著劑時,更可顯著提昇自黏著層中金雀花鹼之釋出性。
本發明之貼附劑,黏著劑係亦可為橡膠系黏著劑。黏著劑為橡膠系黏著劑時,可提高黏著層中金雀花鹼的安定性。且「橡膠系黏著劑」係意指「單獨含有具有共軛雙鍵鍵結的單體或共聚合體之黏著劑」。使黏著劑組成物中含有有機酸或其鹽時,可提高自黏著層中金雀花鹼之釋出性。
本發明之貼附劑,黏著劑組成物亦可進而含有吸收促進劑。使黏著劑組成物中含有吸收促進劑時,可提高金雀花鹼的皮膚通透性。
根據本發明,可提供自黏著層中釋出金雀花鹼具有優異釋出性之貼附劑。
其次,針對本發明貼附劑之實施方式詳細說明。
與本發明有關之貼附劑,係具備支持體。支持體係可使用具伸縮性的或非伸縮性之薄片、薄膜、箔片。並未特別限制支持體的材料,可舉出聚對苯二甲酸乙二酯、聚對苯二甲酸丁二酯、二甲酸乙二醇酯等聚酯、聚乙烯、聚丙烯等聚烯烴、乙烯-乙酸乙烯酯共聚合物、聚氯化乙烯、尼龍、聚胺基甲酸等高分子材料、及紙、鋁等金屬。亦可將該等以織布或不織布的形式提供。支持體亦可為積層體、發泡體、微多孔體等。
貼附劑,係具備配置於支持體之至少一面上之黏著層。黏著層可僅配置於支持體的單面上,亦可配置於支持體的兩面上。進而,黏著層可配置於支持體的單面或兩面之全部區域,亦可配置於一部分的區域。
黏著層由黏著劑組成物構成,黏著劑組成物的酸價為10以下。因黏著劑組成物的酸價為10以下,貼附劑不僅具有優異的自黏著層釋出金雀花鹼之釋出性,亦具有優異的黏著層中之金雀花鹼之安定性以及金雀花鹼之皮膚通透性。酸價5以下為佳,3以下更佳。
酸價係如下所述者。
量取0.4g之黏著劑組成物置入50mL的離心管中,加入以體積比1:1之比例混合甲苯與乙醇之混合液20mL,
並使其溶解。其次,加入0.5mL之酚酞指示劑,並使用0.05mol/L之氫氧化鉀乙醇溶液進行滴定。
另一方面,除未使用黏著劑組成物之外,進行與上述相同方法之空白實驗。自補正空白實驗結果時之0.05mol/L之氫氧化鉀乙醇溶液的滴定量,計算出中和1g的黏著劑組成物所必須的氫氧化鉀的mg數,將之作為酸價。
黏著劑組成物之酸價,可因應需要使黏著劑組成物中含有酸中和劑,使酸價成為10以下。並未特別限制酸中和劑,酸中和劑可舉出例如氫氧化鈉、氫氧化鉀、氫氧化鎂、氫氧化鈣等氫氧化鹼金屬或鹼土金屬、銨鹽、胺等。
黏著劑組成物中,藥物可含有金雀花鹼或其鹽。金雀花鹼或其鹽係作為戒煙輔助劑,用於吸菸者的戒煙、尼古丁依賴症患者的治療等。

以上述方法,測定使貼附劑保存於60℃,濕度75%的條件下2星期之前與之後的金雀花鹼含量,以保存前的金雀花鹼含量為100%時,計算出保存後的金雀花鹼含量的比例(相對於初始%)。
