In particular, multi-dose eye drops generally contain a preservative such as benzalkonium chloride in order to prevent spoilage of the product due to microbial contamination during use.
 特許文献1には、2-アミノ-3-(4-ブロモベンゾイル)フェニル酢酸含有水性液剤組成物において、ブロムフェナクとベンザルコニウム塩化物とを組み合わせることにより、保存効力を有し、安定性に優れる水性液剤組成物を調製したことが報告されている。しかしながら、2-アミノ-3-(4-ブロモベンゾイル)フェニル酢酸含有水性液剤組成物を長期間貯蔵した場合における保存効力については何ら検討されていない。また、その包装形態を検討することも一切記載も示唆もされていない。 Patent Document 1 shows that the aqueous solution composition containing 2-amino-3- (4-bromobenzoyl) phenylacetic acid has storage efficacy and excellent stability by combining bromfenac and benzalkonium chloride. It has been reported that an aqueous liquid composition was prepared. However, no consideration is given to the storage efficacy of the 2-amino-3- (4-bromobenzoyl) phenylacetic acid-containing aqueous solution composition after long-term storage. Also, no consideration or suggestion has been made to examine the form of packaging.

 表1及び表2に示されるように、水性組成物(点眼剤)をピロー包装した、より詳細には脱酸素剤とともにピロー包装した実施例1の被験サンプルは、加速試験開始時のみならず、加速試験終了時においても、5種すべての菌に対して防腐効果を示し、第十七改正日本薬局方 参考情報「保存効力試験法」による基準「カテゴリーIA」の基準に適合した。これに対し、水性組成物(点眼剤)を脱酸素剤とともにピロー包装していない比較例1の被験サンプルは、加速試験開始時には、同基準に適合したが、加速試験終了時においては、防腐効果が減衰しており、同基準に適合しなかった。この結果から、本化合物を含有する水性組成物(点眼剤)を、ピロー包装すること、より好ましくは、脱酸素剤とともにピロー包装することで、よりよく防腐効果、すなわち保存効力が維持されることがわかった。また、水性組成物(点眼剤)を脱酸素剤とともにピロー包装した実施例1の被験サンプルは、長期保存試験開始時及び終了時においても、同基準に適合し、長期間にわたり保存効力が維持されることがわかった。 As shown in Tables 1 and 2, the test sample of Example 1 in which the aqueous composition (eye drops) was pillow-packaged, more specifically, pillow-wrapped with an oxygen scavenger, was used not only at the start of the accelerated test, Even at the end of the accelerated test, it exhibited antiseptic effects against all five types of bacteria, and met the criteria of "Category IA" according to the 17th Amended Japanese Pharmacopoeia Reference Information "Preservation Efficacy Test Method". In contrast, the test sample of Comparative Example 1 in which the aqueous composition (eye drops) was not pillow packaged with the oxygen scavenger met the same criteria at the start of the accelerated test, but the preservative effect at the end of the accelerated test. Was attenuated and did not meet the criteria. From this result, it is better to maintain the preservative effect, that is, the preservation efficacy, by pillow packaging an aqueous composition (eye drops) containing the present compound, more preferably by pillow packaging with an oxygen scavenger. I understand. In addition, the test sample of Example 1 in which the aqueous composition (eye drops) was pillow-packaged with an oxygen scavenger met the same standards at the start and end of the long-term storage test, and the storage efficacy was maintained over a long period It turned out that

 表3に示されるように、水性組成物(点眼剤)をピロー包装した、より詳細には脱酸素剤とともにピロー包装した実施例1の被験サンプルは、加速試験及び長期保存試験中、その水性組成物の乾燥亜硫酸ナトリウムの含有量に大きな変化が生じなかった。これに対し、水性組成物(点眼剤)をピロー包装していない比較例1の被験サンプルは、加速試験及び長期保存試験中、乾燥亜硫酸ナトリウムの含有量は大きく減少していた。この結果から、本化合物を含有する水性組成物(点眼剤)を、ピロー包装することで、より好ましくは、脱酸素剤とピロー包装することで、水性組成物(点眼剤)の乾燥亜硫酸ナトリウムの含有量がよりよく維持されることがわかった。なお、同様に、実施例1の被験サンプル及び比較例1の被験サンプルにおける水性組成物(点眼剤)のベンザルコニウム塩化物を定量したが、実施例1の被験サンプル及び比較例1の被験サンプルのいずれも、ベンザルコニウムの含有量に大きな変化は生じなかった(データは示さず)。 As shown in Table 3, the test sample of Example 1 in which the aqueous composition (eye drops) was pillow-packaged, more particularly pillow-wrapped with the oxygen scavenger, had its aqueous composition during the accelerated test and the long-term storage test. There was no significant change in the dry sodium sulfite content of the product. On the other hand, in the test sample of Comparative Example 1 in which the aqueous composition (eye drops) was not packaged by pillow, the content of dry sodium sulfite was significantly reduced during the accelerated test and the long-term storage test. From this result, it is more preferable that the aqueous composition (eye drops) containing the present compound is pillow-packaged, more preferably, the aqueous composition (eye-drops) dried sodium sulfite is pillow-wrapped. It was found that the content is better maintained. Similarly, although the benzalkonium chloride of the aqueous composition (eyedrops) in the test sample of Example 1 and the test sample of Comparative Example 1 was quantified, the test sample of Example 1 and the test sample of Comparative Example 1 There was no significant change in the benzalkonium content in any of the cases (data not shown).
 また、表4に示されるように、水性組成物(点眼剤)をピロー包装した、より詳細には脱酸素剤とともにピロー包装した実施例1の被験サンプル及び水性組成物(点眼剤)をピロー包装していない比較例1の被験サンプルのいずれも、加速試験中、その水性組成物のブロムフェナクナトリウム水和物の含有量に大きな変化が生じなかった。また、加速試験開始後6ヵ月において、実施例1における水性組成物中には、ブロムフェナク類縁物質(ブロムフェナクナトリウム水和物に対して0.05%以上存在)が2種生じていたのに対し、比較例1における水性組成物中には、ブロムフェナク類縁物質(ブロムフェナクナトリウム水和物に対して0.05%以上存在)が5種生じていた(下記表5に示す)。この結果から、本化合物を含有する水性組成物(点眼剤)を、ピロー包装することで、より好ましくは脱酸素剤とともにピロー包装することで水性組成物(点眼剤)中のブロムフェナク類縁物質の生成が抑制されることがわかった。 In addition, as shown in Table 4, the test sample of Example 1 in which the aqueous composition (eyedrops) was packaged by pillow, more specifically, the pillow package was packaged with the oxygen scavenger, and the aqueous composition (eyedrops) was packaged by pillow During the accelerated test, none of the test samples of Comparative Example 1 that did not perform significant changes in the content of bromfenac sodium hydrate in the aqueous composition. In addition, in the aqueous composition in Example 1, two kinds of bromfenac analogues (0.05% or more relative to bromfenac sodium hydrate) were produced in the aqueous composition in six months after the initiation of the accelerated test. On the other hand, in the aqueous composition in Comparative Example 1, five bromfenac analogues (0.05% or more relative to bromfenac sodium hydrate) were generated (shown in Table 5 below). From this result, it is more preferable to pillow-package an aqueous composition (eyedrops) containing the present compound, and more preferably, to form bromfenac analogues in the aqueous composition (eyedrops) by pillow-packing with an oxygen scavenger. Was found to be suppressed.
