以下に、実施例を挙げて本発明をさらに具体的に説明するが、本発明はこれらの実施例により何ら限定されるものではなく、多くの変形が本発明の技術的思想内で当分野において通常の知識を有する者により可能である。 The present invention will be described in more detail below with reference to Examples, but the present invention is not limited to these Examples in any way, and many modifications can be made within the technical idea of the present invention in the art. It is possible for a person with ordinary knowledge to do so.
下記表に示す組成の水性眼科組成物(点眼剤)を調製し、次のようにして、析出を評価した。 Aqueous ophthalmic compositions (eye drops) having the composition shown in the table below were prepared, and precipitation was evaluated as follows.
調製した組成物200g(200cm3)を、硝子スクリュー瓶10mLに充填し、室温でそれぞれ1時間保管した後、析出(白濁)の有無及び程度を目視にて確認した。 200 g (200 cm 3 ) of the prepared composition was filled into 10 mL glass screw bottles and stored at room temperature for 1 hour, and then the presence and extent of precipitation (white turbidity) was visually confirmed.
そして、以下の基準で、試験例1に対する析出の程度を評価した。 Then, the degree of precipitation for Test Example 1 was evaluated based on the following criteria.
〇:析出なし
△:試験例1と析出の程度において同等
×:試験例1よりも析出が多い
〇: No precipitation △: Same degree of precipitation as Test Example 1 ×: More precipitation than Test Example 1
結果を下記表に示す。なお、下記表の水性眼科組成物において、各成分の単位は(w/v%)である。 The results are shown in the table below. In addition, in the aqueous ophthalmic compositions shown in the table below, the unit of each component is (w/v%).
上記表の結果から明らかなように、意外なことに、エピナスチン塩酸塩やプラノプロフェンを含むだけでは析出が生じないにもかかわらず、エピナスチン塩酸塩とプラノプロフェンを組み合わせることで析出が生じることがわかった(試験例1~3)。 As is clear from the results in the table above, surprisingly, precipitation does occur when epinastine hydrochloride and pranoprofen are combined, although precipitation does not occur when only epinastine hydrochloride or pranoprofen is included. was found (Test Examples 1 to 3).
そして、このような析出は、特定の成分を使用することで効率よく抑えることができた(試験例4~19)。通常、界面活性剤を用いればこのような析出を抑えられる場合が多いところ、ごく一般的な界面活性剤では、析出抑制効果がないばかりか、むしろ析出が増えており(試験例20)、このような結果は極めて意外なものであった。 Such precipitation could be effectively suppressed by using specific components (Test Examples 4 to 19). Normally, such precipitation can be suppressed by using a surfactant, but very common surfactants not only have no effect on suppressing precipitation, but also increase precipitation (Test Example 20). These results were extremely surprising.
このように析出抑制効果を確認できた試験例4~19の組成物につき、さらに性状等を調べた。 The properties of the compositions of Test Examples 4 to 19, in which the precipitation suppressing effect was confirmed in this way, were further investigated.
まず、これらの組成物は、いずれも、点眼容器(PET製、口径6mm)に支障なく充填でき、充填性に優れていた。 First, all of these compositions could be filled into eye drop containers (made of PET, diameter 6 mm) without any problem, and had excellent filling properties.
また、点眼容器から組成物を滴下したところ、いずれも液切れが良好であった。そのため、得られた組成物は、いずれも、液だれが生じにくい組成物であることがわかった。 In addition, when the composition was dropped from an eyedropper container, the liquid drained well in all cases. Therefore, it was found that all of the obtained compositions were compositions that did not easily cause dripping.
さらに、組成物を、それぞれ、無色透明のプラスチックフィルム上に滴下し、水を蒸発させた。蒸発後の状態を目視で確認したところ、いずれも白残り(不揮発分による白化現象又は析出)が生じないか又はほとんど生じなかった。このように、得られた組成物は、いずれも、効率よく製剤化できる組成物であることが確認できた。実際、前記点眼容器に充填する際、いずれの組成物も製造ライン(ノズル等)に白残りを生じさせることはなかった。 Further, each of the compositions was dropped onto a colorless and transparent plastic film, and the water was evaporated. When the state after evaporation was visually confirmed, no or almost no white residue (whitening phenomenon or precipitation due to nonvolatile matter) was observed in all cases. Thus, it was confirmed that all of the obtained compositions can be formulated efficiently. In fact, none of the compositions caused any white residue on the production line (nozzles, etc.) when filled into the eye drop containers.
さらにまた、各組成物において、(c)成分の機能を有効に発揮していた。例えば、試験例5では、濃グリセリンを使用しているが、等張化剤としての機能を損なうことなく発揮していた。 Furthermore, each composition effectively exhibited the function of component (c). For example, in Test Example 5, concentrated glycerin was used, and it exhibited its function as an isotonic agent without impairing its function.
