Definitions

  • Bioadhesion results from a confluence of factors, including an intimate contact between the bioadhesive and the receptor tissue, penetration of the bioadhesive into the crevice of the tissue surface and/or mucus, and formation of mechanical, electrostatic, or chemical bonds. Bioadhesive properties of polymers are affected by both the nature of the polymer and by the nature of the surrounding media.

Abstract

L'invention porte sur un système d'administration de médicaments bioadhésifs selon lequel un noyaux contenant le médicament, soit seul, soit revêtu d'un système à membrane de régulation de la vitesse de libération, est enveloppé d'un revêtement bioadhésif, formant ainsi un système monolithique permettant une libération régulière du médicament. L'invention porte également sur des polymères à propriétés bioadhésives améliorées, et sur des méthodes d'amélioration de la bioadhérence de polymères.
