Abstract
Description
しかしながら、水を含むものであるため微生物によって汚染され易い、という問題がある。特に、点眼剤や点鼻剤、点耳剤等の繰り返し使用されることが多い剤形の場合には、例え滅菌済みの容器等に充填した場合であっても、使用の都度、水性組成物が非無菌の外気に接触するため、微生物汚染のリスクが増大する。
しかしながら、こうした防腐剤には細胞毒性等の問題点があることも指摘されており(例えば、非特許文献1)、例えば水性組成物を点眼剤として用いた場合には角膜損傷をきたすおそれもあることから、その使用量は極力最低限に留めたい。
この点、複数種の成分の組み合わせの協力作用により優れた防腐効果を奏する水性組成物の処方が確立できれば、その分だけ各種防腐剤単独での使用量を低減させることが出来るため、ひいてはより安全性の高い水性組成物の提供が可能となる。
しかしながら、これらのハロゲン化イソキノリン誘導体の防腐効果についてはこれまでに一切知られていない。

次に、「防腐効果付与方法」に係る態様の発明について説明する。
具体的には例えば、第十六改正日本薬局方 参考情報「保存効力試験法」に従い、細菌(例えば、緑膿菌(Pseudomonas aeruginosa)、黄色ブドウ球菌(Staphylococcus aureus)、大腸菌(Escherichia coli))あるいは真菌(例えば、カンジダ(Candida albicans))を用いた場合において、前記一般式(1)で表される化合物若しくはその塩又はそれらの溶媒和物及び第4級アンモニウム型界面活性剤の両成分を共に配合しない対照(防腐効果が無いことが知られている精製水を対照として用いればよい。)と比較して、いずれか1種以上の微生物種において任意の日数において生菌数が少ないことを確認できれば防腐効果有り、と判定され、この場合、水性組成物への防腐効果の付与が確認される。
リパスジルの微生物(細菌及び真菌)に対する発育阻止活性の有無を確認するため、細菌として緑膿菌(Pseudomonas aeruginosa)を、真菌としてカンジダ(Candida albicans)を用い、以下の試験を実施した。
Pseudomonas aeruginosa NBRC 13275株を、ソイビーン・カゼイン・ダイジェスト培地(メルク社)に播種し、30~35℃で20~22時間培養した。培養後、ペプトン食塩緩衝液(pH7.0)にて1000CFU/mL以下となるように希釈し、試験菌懸濁液を得た。
リパスジル1塩酸塩2水和物 2gを270mLのリン酸緩衝液(pH7.2)に溶解し、試料希釈液を得た。
試料希釈液50mLに試験菌懸濁液0.5mLを混合し、試料サンプルを得た(なお、リン酸緩衝液(pH7.2)50mLに試験菌懸濁液0.5mLを混合したものを対照サンプルとした。)。
30分以上経過した後、メンブランフィルター法に従い、セルロース混合エステル性のフィルター(ミリポア社)を用いて各種サンプルをろ過して菌体をフィルター上に回収した後、フィルターをリン酸緩衝液(pH7.2)100mLにて洗浄した。得られたフィルターをソイビーン・カゼイン・ダイジェストカンテン培地(メルク社)上に乗せ、30~35℃で3日間培養した。
培養後、形成されたコロニー数をカウントした(なお、試験を2回実施し、その平均値を得た。)。また、得られたコロニー数から、以下の式により発育阻止率(%)を算出した。
Candida albicans NBRC 1594株を、サブロー・ブドウ糖液体培地(メルク社)に播種し、20~25℃で44~46時間培養した。その後、ペプトン食塩緩衝液(pH7.0)にて1000CFU/mL以下となるように希釈し、試験菌懸濁液を得た。得られた試験菌懸濁液を用いて、前記した緑膿菌に対する試験と同様の操作を行い、菌体をフィルター上に回収した。得られたフィルターをサブロー・ブドウ糖カンテン培地(メルク社)上に乗せ、20~25℃で5日間培養した。
培養後、形成されたコロニー数をカウントした(なお、試験を2回実施し、その平均値を得た。)。また、発育阻止率(%)を算出した。
結果を表1に示す。
以上の試験結果から、リパスジルに代表される一般式(1)で表される化合物若しくはその塩又はそれらの溶媒和物は、細菌及び真菌に対し防腐効果を有することが明らかとなった。
リパスジルとベンザルコニウムとを組合わせることによる微生物(細菌及び真菌)に対する防腐効果の増強の有無を確認するため、細菌として緑膿菌(Pseudomonas aeruginosa)を、真菌としてカンジダ(Candida albicans)を用い、以下の試験を実施した。
なお、ベンザルコニウム塩化物の有効濃度は0.002~0.01%であり、0.001%では十分な殺菌活性を示さないことが知られている(株式会社南山堂1984年発行『点眼剤』、第76~83頁)。そこで、本試験では当該量のベンザルコニウム塩化物を用いることにより、リパスジルとベンザルコニウムとの協力作用(相乗作用)の有無を確認した。
Pseudomonas aeruginosa NBRC 13275株を、ソイビーン・カゼイン・ダイジェストカンテン培地(メルク社)に播種し、30~35℃で、18~24時間培養した。その後、培養菌体を0.1%ペプトン食塩緩衝液(日本製薬社)に浮遊させ、1mL当たり菌体が約108個となるように調整し、試験菌懸濁液を得た。
下記の方法で調製した各種製剤サンプル15mLに対し、試験菌懸濁液を0.1mL接種した後、滅菌したポリプロピレン製の点眼剤用容器(容量:20mL)に充填し、20~25℃で遮光条件下、14日間保存した。
保存後、各種製剤サンプルをレシチン・ポリソルベート80添加ソイビーン・カゼイン・ダイジェスト培地(日本製薬社)で順次10倍ずつ希釈した希釈系列を調製し、カンテン平板混釈法に従いレシチン・ポリソルベート80添加ソイビーン・カゼイン・ダイジェストカンテン培地(日本製薬社)に混釈し、30~35℃で5日間培養した。
培養後、形成されたコロニー数と希釈倍数とから、各種製剤サンプル1mL中の生菌数を算出した。
Candida albicans NBRC 1594株を、サブロー・ブドウ糖カンテン培地(メルク社)に播種し、20~25℃で40~48時間培養した。その後、培養菌体を0.1%ペプトン食塩緩衝液(日本製薬社)に浮遊させ、1mL当たり菌体が約108個となるように調整し、試験菌懸濁液を得た。得られた試験菌懸濁液を用いて、前記した緑膿菌に対する試験と同様の操作を行い、試験菌懸濁液を接種した各種製剤サンプルを保存した。
保存後、各種製剤サンプルをレシチン・ポリソルベート80添加ソイビーン・カゼイン・ダイジェスト培地(日本製薬社)で順次10倍ずつ希釈した希釈系列を調製し、カンテン平板混釈法に従いレシチン・ポリソルベート80添加サブロー・ブドウ糖カンテン培地(日本製薬社)に混釈し、20~25℃で5日間培養した。
培養後、形成されたコロニー数と希釈倍数とから、各種製剤サンプル1mL中の生菌数を算出した。
100mL当たり、リパスジル1塩酸塩2水和物 0.4896g(リパスジルのフリー体として0.4g)、無水リン酸二水素ナトリウム 0.4g、グリセリン 2.136g、水酸化ナトリウム 適量(pH 6.0)及び滅菌精製水(残余)を含有する水性組成物を調製し、フィルター滅菌して製剤サンプルとした。
<リパスジル及びベンザルコニウムを含有する製剤サンプル>
100mL当たり、リパスジル1塩酸塩2水和物 0.4896g(リパスジルのフリー体として0.4g)、ベンザルコニウム塩化物 0.001g(0.001w/v%)、無水リン酸二水素ナトリウム 0.4g、グリセリン 2.136g、水酸化ナトリウム 適量(pH 6.0)及び滅菌精製水(残余)を含有する水性組成物を調製し、フィルター滅菌して製剤サンプルとした。
以上の試験結果から、リパスジルに代表される一般式(1)で表される化合物若しくはその塩又はそれらの溶媒和物と、ベンザルコニウムに代表される第4級アンモニウム型界面活性剤とを組み合わせることにより、相乗的に防腐効果が増強され、第4級アンモニウム型界面活性剤単独では防腐効果を示さないような量であっても優れた防腐効果が奏されることが明らかとなった。
細菌として緑膿菌(Pseudomonas aeruginosa)の代わりに黄色ブドウ球菌(Staphylococcus aureus:NBRC 13276株)を用いたほかは試験例2と同様の方法により、試験を実施した。
結果を表3に示す。
細菌として緑膿菌(Pseudomonas aeruginosa)の代わりに大腸菌(Escherichia coli:NBRC 3972株)を用い、保存期間を28日間としたほかは試験例2と同様の方法により、試験を実施した。
結果を表4に示す。
以上の試験結果から、リパスジルに代表される一般式(1)で表される化合物若しくはその塩又はそれらの溶媒和物と、ベンザルコニウムに代表される第4級アンモニウム型界面活性剤とを組み合わせることにより、広い範囲の微生物に対して優れた防腐効果の増強が認められることが明らかとなった。
表5~表7に記載の成分及び分量(水性組成物100mL当たりの量(g))を含有する点眼剤を、常法により製造できる。
製造例1~27において、ベンザルコニウム塩化物の代わりに同量のベンゼトニウム塩化物を用いたものを、製造例28~54の点眼剤として、常法により製造できる。
