Abstract
Description
薬理的−技術的観点からは、脂溶性化合物は、本願明細書に記載の発明に従ったエマルションまたはマイクロエマルションの油層(単に「油」とも呼ぶ)を構成する。生理学的観点からは、多くの脂溶性化合物は浸透促進剤として働くことができ、粘膜、好ましくはS状結腸及び/又は直腸の粘膜を通しての染料の吸収を促進する。脂溶性化合物はまた、潤滑剤としても働いて、糞便材料、排泄物及び/又は粘液の排出(洗浄)を有利にする。
薬理的−技術的観点からは、共乳化剤は、本願明細書に記載の発明に従ったエマルションまたはマイクロエマルションの任意選択成分として使用することができる。すなわち、乳化剤と一緒になって、安定化に寄与する。生理学的観点からは、多くの共乳化剤は、浸透促進剤として働くことができ、粘膜、好ましくはS状結腸及び/又は直腸の粘膜を通しての染料の吸収を促進する。
薬理的−技術的観点からは、粘度調整剤は、本願明細書に記載の発明に従ったエマルションまたはマイクロエマルションの安定化に寄与する。製剤の粘度を増加させることで、分散相滴の合体現象をより困難にするからである。生理学的観点からは、多くの粘度調整剤は、生体接着特性を有し、本願発明の組成物が、粘膜、好ましくはS状結腸及び/又は直腸の粘膜の壁へ付着することに寄与し、もってエマルションまたはマイクロエマルションと粘膜壁との間の接触時間を増加させ、生体染色染料の場合、より大きな吸収確率を決定する。
薬理的−技術的観点からは、逆感熱性ポリマーは、本願明細書に記載の発明に従ったエマルションまたはマイクロエマルションの安定化に寄与する。製剤の粘度を増加させることで、分散相滴の合体現象をより困難にするからである。生理学的観点からは、逆感熱性ポリマーは、本願明細書に記載の発明に従ったエマルションまたはマイクロエマルションの、粘膜壁、好ましくはS状結腸及び/又は直腸の粘膜壁への接着性の強化に寄与する。すなわち、臨界ゲル化濃度(CGC)を超える濃度での、本願発明の前記ポリマーエマルション又はポリマーエマルションの添加により、温度の増加、好ましくは室温(すなわち、約20〜25℃)から体温(すなわち、約37℃)への温度増加に応答した、前記エマルションまたはマイクロエマルションの粘度の増加が保証される。これは、前記エマルションまたはマイクロエマルションと粘膜壁との間の接触時間を増加させるのに役立つ。逆感熱性ポリマーはまた、界面活性剤として働くことができ、そのままで表面張力を低下させることにより、糞便材料、排泄物及び/又は粘液の除去に寄与する。
染料自体が、S状結腸及び/又は直腸の粘膜の上皮細胞の細胞膜を通過することを容易にするという、本願発明のエマルションまたはマイクロエマルションの能力・特性により、染料の吸収を増加させる。この染色は主に、S状結腸及び/又は直腸の(色素沈着)粘膜の表面層上にある、及び/又は
2)
本願発明のエマルションまたはマイクロエマルションと、S状結腸及び/又は直腸の粘膜壁の間の接触時間を増加させる。さらに、生体接着特性を有する粘度調整剤、及び/又は逆感熱性ポリマーの活用を可能とすれば、到達技術水準において既知の溶液(たとえば、単純な水溶液)と比較して、粘膜壁自体に沿った流動傾向の低下した薄膜を形成することにより、本願発明のエマルションまたはマイクロエマルションの粘膜壁への付着を増加させることができる。結果として、本願発明の対象であるエマルションまたはマイクロエマルションの形態にある特別な液体組成物中に溶解した染料は、溶液の形態(たとえば、単純な水溶液)で製剤化された組成物中に溶解した染料と比較して、粘膜の上皮細胞の細胞膜とより長い時間、接触した状態に留まる。驚くべきことに、これらの特性の組み合わせにより、当該技術分野において一般に使用されている染料溶液(たとえば水溶液)等、これまでの到達技術水準で既知の組成物と比較して、本明細書に記載の発明に従ったエマルションまたはマイクロエマルションの形態の液体組成物に一定の利点が与えられることが発見された。
