Description
本発明によれば、3−エチルピリジン等の有効成分を含んでなる子宮内製剤を子宮内に投与することにより、子宮腺筋症を治療および予防できる。3−エチルピリジンが子宮内膜の腺管を通じて腺筋症組織に浸透することにより、子宮腺筋症が治療されると考えられる。子宮内において継続的に有効成分を放出させる観点から、子宮内製剤としてはDDS効果を有するマトリックス製剤が好ましい。
本発明によれば、3−エチルピリジン等の有効成分を含んでなる膣内製剤を患者の膣内に投与することにより、子宮内膜症(特に、深部内膜症、ダグラス窩内膜症、膣内膜症、および腹膜内膜症)を効果的に治療および予防できる。膣内製剤に直接接触した膣粘膜から有効成分が吸収され、直腸・膣中隔にある深部内膜症組織内に浸透することにより深部内膜症やダグラス窩内膜症を治療および予防できると考えられる。膣内において継続的に有効成分を放出させる観点から、膣内製剤としてはドーナツ型膣内リングのような膣内リングが好ましい。
本発明によれば、3−エチルピリジン等の有効成分を含んでなる膣錠または膣坐剤を膣内に投与することにより、子宮内膜症(特に、深部内膜症、ダグラス窩内膜症、膣内膜症、および腹膜内膜症)を治療および予防できる。治療および予防に当たっては、例えば、就寝前に膣内にこれらの製剤を深く挿入させる。
本発明によれば、3−エチルピリジン等の有効成分を含んでなる液剤を患部組織に直接投与することにより、子宮内膜症(特に、卵巣内膜症性嚢腫(卵巣チョコレート嚢腫)、深部内膜症、ダグラス窩内膜症、腹膜内膜症)を治療および予防できる。
子宮腺筋症の患者(35歳)に対して本発明による治療剤を用いて治療を行った。この患者は内膜症治療薬であるリュープリンの注射を毎月1回6カ月間続けていたが、治癒しなかった。この時、子宮は妊娠3ヶ月相当の大きさに腫大し、月経痛がひどく、月経中の出血量も多かった。また血中のCA125は441単位(正常単位は35単位以下)、CA602は1025単位(正常値は63単位以下)と異常高値を示した。
GnRHアナログの点鼻または注射後に再発した子宮腺筋症患者(12例)に対し3−エチルピリジン600〜900μg含有子宮内器具(IUD,Intrauterine device)を6ヶ月間子宮内に挿入した。その結果、過多月経は消失9例、改善3例であり、月経痛も消失8例、改善4例であり、全例において治療効果が認められた。一方で、月経時のIUD脱落率が20%と高率であった。
子宮内膜症のため左卵巣およびダグラス内膜症を切除した後、子宮内膜症が再発した患者(33歳)に対して本発明による治療剤を用いた治療を行った。この患者には膣の深部右後壁に奥行き約7cm、幅約5cmの硬結が認められ、生体組織検査で膣内膜症であることが認められた。また、月経痛が認められ、月経以外の時期に、強い下腹痛、排便痛および性交痛が認められた。
卵巣チョコレート嚢腫の患者に対して本発明による治療剤を用いた治療を行った。この患者は、経膣超音波診断により、ダグラス窩に直径6cmの嚢腫が認められた。また血中のCA125は1522単位、CA602は352単位と異常高値を示した。嚢腫の膣壁からの距離が1cm以内であることを確認し、経膣超音波で観察しながら後膣円蓋から針で嚢胞内容を穿刺し、吸引除去した。その後、エタノール液2mlに3−エチルピリジン2mgを溶解した液剤を注入したところ、4週間後に卵巣チヨコレート嚢腫は消失し、卵巣の直径2.5cmにまで縮小し、月経痛は消失した。また、血中のCA125は52単位まで、CA602は61単位まで下降した。
深部内膜症により激しい月経痛に悩まされていた患者(34歳)に対して本発明による治療剤を用いた治療を行った。この患者にまず、ダナゾール1000mgを含有する膣リングを6ヶ月間膣内に挿入したところ、血中CA125は950単位から620単位に減少し、月経痛は軽減したが全治しなかった。また、ダグラス窩の有痛性硬結も縮小しなかった。次に、3−エチルピリジン10mgを含有する膣リングを挿入したところ、3ヶ月でCA125は250単位になり、月経痛は更に減少したが、ダグラス窩の硬結は縮小しなかった。そこで、ダナゾール1000mgおよび3−エチルピリジン10mgを含有する膣リングを挿入したところ、2ヶ月で月経痛は消失した。また、3ヶ月でダグラス窩の有痛性硬結は触診不能となり、CA125も正常値まで下降し、深部内膜症は全治した。
深部内膜症患者(18例)に対し3−エチルピリジン8〜10mg含有膣リングを3ヶ月間膣内に挿入した。その結果、ダグラス窩の圧痛および硬結の消失を9例に、改善を7例に、無効を2例に認めた。月経痛は4例で消失、13例で改善、無効は1例のみであった。性交痛、排便痛はそれぞれ10例で消失し、7例で改善した。
