Abstract
Description
1.ビサコジルおよびジオクチルソジウムスルホサクシネートを含有する核が、小腸下部から大腸部位において薬物を放出する腸溶性被覆剤で被覆されていることを特徴とする固形製剤。
2.核に軽質無水ケイ酸を配合したことを特徴とする上記1記載の固形製剤。
3.日本薬局方崩壊試験方法における第1液で2時間不溶、第2液で崩壊時間が60分を越える、上記1または2に記載の固形製剤。
である
本発明において核とは腸溶性被覆を施す対象物であり、ジオクチルソジウムスルホサクシネートおよびビサコジルを配合した粉体を造粒した顆粒、素錠の他、粉剤、ゲルなども含有する。
実施例1と同様に製造した核粒子に皮膜を施さないものを比較例1とした。
実施例1および比較例1で示される製剤の溶出試験を行った。試験法としては日本薬局方の溶出試験第3法(フロースルーセル法)に従い、溶出するジオクチルソジウムスルホサクシネートをHPLCにて定量した。本試験はセル内に供給する試験液の液性を経時的に変化させることから人消化管内における製剤の挙動を再現した試験になっており、部位指向性製剤の溶出性を評価するのに適している。なお試験液性および溶出時間は表2に示した。
本製剤は一般の腸溶性製剤と違い薬物放出が消化管の下部にて開始されるところに特徴があり、これにより下剤としての効果が高まるものといえる。これを実証するために、本製剤とビサコジルを含有する一般の腸溶性製剤(市販品)の崩壊性および溶出性を比較した。
フロースルーセル法にてビサコジルを指標として実施例1および市販品の薬物放出特性を調べた。結果を図2に示した。
ビサコジルとジオクチルソジウムスルホサクシネートの共存下におけるビサコジルの溶解度変化を調査した。ビサコジルを精製水に分散させ、一定条件下で5時間振とうさせた液を3000min-1、5minの条件にて遠心分離した。その後、上澄液を採取しHPLCにてビサコジルの溶解量を定量した。
1.試験方法
SD系雄性ラットを1群10例として使用した。被験物質としてビサコジル(2mg/kg)単独、DSS単独(3.2mg/kg)、ビサコジル(2mg/kg)+DSS(3.2mg/kg)を用いた。
1)回腸内投与試験
ラットをエーテル麻酔下開腹し、回盲部より20cm口側の回腸にシリンジを用いて被験物質をラットの体重1kgあたり1mLの割合で注入した。閉腹後、麻酔より回復させ24時間後まで瀉下の発現を観察した。
2)経口投与試験
ラットに被験物質を体重1kgあたり5mLの割合で経口投与し、24時間後まで瀉下の発現を観察した。
Claims (3)
- ビサコジルおよびジオクチルソジウムスルホサクシネートを含有する核が、小腸下部から大腸部位において薬物を放出する腸溶性被覆剤で被覆されていることを特徴とする固形製剤。
- 核に軽質無水ケイ酸を配合したことを特徴とする第1項記載の固形製剤。
- 日本薬局方崩壊試験方法における第1液で2時間不溶、第2液で崩壊時間が60分を越える、第1項または第2項に記載の固形製剤。
