Abstract
本發明提供一種點眼液,其係含有超過0.075%(w/v)的濃度之依匹斯汀(epinastine)或其鹽之點眼液,其實質上不含有防腐劑及具防腐作用的成分。
Description
本發明係關於一種點眼液(以下,亦稱為「本發明之點眼液」),其係含有超過0.075%(w/v)的濃度之依匹斯汀(epinastine)或其鹽之點眼液,其特徵為實質上不含有防腐劑及具防腐作用的成分。
點眼液係為了防止伴隨著重複的使用之菌類等的繁殖,而被要求有一定以上的防腐對策。因此,點眼液中通常摻合有防腐劑。作為防腐劑,例如苄烷銨氯化物係水溶性、化學上穩定,且與其他防腐劑相比其防腐效力亦高,所以廣泛地被使用於點眼液。但是,苄烷銨氯化物具有細胞毒性,若曝露量增加,則引起角膜上皮障礙之可能性會變大。因此,無法使用於特別對苄烷銨氯化物顯示過敏反應之患者、或具有重度角膜上皮障礙之患者。
目前,在日本上市之Arejion(註冊商標)點眼液0.05%,係以依匹斯汀鹽酸鹽為有效成分之點眼液,其不添加如苄烷銨氯化物之防腐劑,取而代之添加了具防腐作用的其他成分(硼酸、乙二胺四乙酸(edetic acid, EDTA))(非專利文獻1)。即,為了重複使用含有依匹斯汀或其鹽之點眼液,已知道可不必含有如苄烷銨氯化物之防腐劑,但有需要藉由取代其之其他具防腐作用的成分來確保防腐效力。另一方面,不添加防腐劑及具防腐作用的成分之任一者並且含有依匹斯汀或其鹽之點眼液,則完全未被知悉。
此外,在上市之點眼液中,已知有不添加防腐劑及具防腐作用的成分之任一者的點眼液,但該等係單一劑量(unit dose)型(1次用完的類型)者、或保存於無防腐劑的容器(具有用以發揮防腐效果之特別構造的容器)者,而如有效成分本身會發揮防腐作用的點眼液並未被知悉。即,依匹斯汀或其鹽本身具有防腐作用一事係完全未被知悉。
[非專利文獻1]Arejion(註冊商標)點眼液0.05%藥品仿單
因此,提供一種實質上不含有防腐劑及具防腐作用的成分並且含有依匹斯汀或其鹽之點眼液,係令人興奮的課題。
本發明人等為了找到未添加防腐劑及具防腐作用的成分之任一者、或該等的量減量之含有依匹斯汀 或其鹽的點眼液,而進行專心研究,結果發現:藉由使點眼液中之依匹斯汀或其鹽的濃度超過0.075%(w/v),而可實質上不含有防腐劑或具防腐作用的成分,且得到充分的防腐效果,遂而完成本發明。具體而言,本發明提供以下。

本發明中,所含有之依匹斯汀或其鹽可採用水合物或溶劑合物之形態。
本發明中,依匹斯汀或其鹽之含量,只要為超過0.075%(w/v)就足夠,但亦可設為0.085%(w/v)以上、或0.1%(w/v)以上,其上限只要為作為眼科製劑所容許的濃度即可,例如為5%(w/v)。就依匹斯汀或其鹽之含量而言,較佳為0.1~5.0%(w/v),更佳為0.1~3.0%(w/v),進一步較佳為0.1~1.0%(w/v)。特佳為0.1~0.5%(w/v)、0.1~0.3%(w/v),惟0.1%(w/v)、0.2%(w/v)、0.3%(w/v)、0.4%(w/v)、0.5%(w/v)也進一步更佳。
此外,在本發明中含有依匹斯汀的鹽之情形,該等值係依匹斯汀的鹽之含量。「%(w/v)」意指本發明之點眼液100mL中所含之對象成分(此處指依匹斯汀或其鹽)的質量(g)。以下,只要無特別說明則同樣。

實施例2
實施例3
實施例4
1mL中
依匹斯汀鹽酸鹽 2mg
比較例1
比較例2
2.試驗方法
使用以下的菌株作為接種菌。
細菌:大腸桿菌,Escherichia Coli ATCC 8739(亦稱為E.coli)
綠膿桿菌,Pseudomonas aeruginosa ATCC 9027(亦稱為P.aeruginosa)
金黃色葡萄球菌,Staphylococcus aureus ATCC6538(亦稱為S.aureus)
酵母菌及黴菌類:念珠菌,Candida albicans ATCC 10231(亦稱為C.albicans)
黑麴菌,Aspergillus brasiliensis ATCC16404(亦稱為A.brasiliensis)
將接種菌液接種至試驗試料,使包含各製劑之試驗試料中的菌液濃度成為105~106個/mL(共5菌種)。具體而言,係調製接種菌液使成為107~108cfu/mL,並將各接種菌液接種至包含實施例1~4及比較例1~2之製劑的試驗試料,使該接種菌液成為105~106cfu/mL,均勻地混合而製成試料。將該等試料在遮光下20~25℃保存,在各樣本點(7日後、14日後、或28日後)中,利用微量吸管自各試料採取1mL,測定生菌數。於各樣本點,係進行將試料溶液的蓋子打開而實施採樣並關閉蓋子之操作。
3.試驗結果及考察
將試驗結果示於表1及表2。表1及表2之試驗結果係利用接種時的菌數(B)對測定生菌數時的菌數(A)之比(B/A)的常用對數值來表示,例如,在值為「1」之情形中,顯示了檢查時的生菌數係減少為接種菌數的10%。
關於試驗是否合格的判定,係將下述任一者都滿足時,當成合格:對於細菌種類(E.coli、P.aeruginosa、S.aureus),在播種7日後為1.0以上、且在14日後或28日後為3.0以上;以及對於真菌種類(C.albicans、A.brasiliensis),與播種7日後相比,播種14日後或28日後的數值並未減少。
如表1及表2所示,含有依匹斯汀或其鹽之實施例1~4的製劑,儘管不含有防腐劑及具防腐作用的成分,卻對任一菌都顯示充分的防腐效果。相對於此,比較例1及比較例2之製劑顯示了不具有充分的防腐效果。藉此,暗示了:含有超過0.075%(w/v)的濃度之依匹斯汀或其鹽之本發明之點眼液,係即使不含有防腐劑及具防腐作用的成分,亦可作為多劑量型點眼液而重複開閉容器來使用。
本發明係提供一種點眼液,其係含有超過0.075%(w/v)的濃度之依匹斯汀或其鹽之點眼液,其實質上不含有防腐劑及具防腐作用的成分。
