시클로덱스트린과 소염진통제간의 포접복합체에 관한 연구 (Ⅱ) : 2-히드록시프로필-β-시클로덱스트린이 이부프로펜 좌제의 방출에 미치는 영향 = Inclusion Complex of Analgesic and antiinfiammatory Agents with Cyclodextrins (Ⅱ) : Effect of 2-Hydroxypropyl-β-cyclodextrin on the Release of Ibuprofen Suppository

다국어 초록 (Multilingual Abstract)

Ibuprofen, a nonsteroidal antiinflammatory, analgesic and antipyretic drug, has several limitations in clinical application because of low solubility in water and gastrointestinal irritation. Effect of ibuprofen/2-hydroxypropyl-β-cyclodextrin (HPβCD) inclusion compound on release of suppository was investigated. Complex formation was confirmed by ¹H- and ^(13)C-NMR spectroscopy. The release of ibuprofen from suppository base in vitro was significantly increased by the complexation with HPβCD. The release of ibuprofen from hydrophilic base was faster than that from hydrophobic base. In vivo studies, the release rate of ibuprofen from suppository was accelerated after rectal administration in complex form. This results suggested that ibuprofen/HPβCD complex can be practically used for suppository to have faster effect of ibuprofen with reduced side effect.
