Abstract:
An adhesive composition with a sustained medicament releasability, comprised of a medicament, a hydrophilic composition, and a binding composition capable of retaining the hydrophilic composition, said hydrophilic composition being soluble in water, humor and exudate, and being selected from the group consisting of natural hydrophilic compositions, semi-synthetic hydrophilic compositions and synthetic hydrophilic compositions and mixtures thereof, said medicament being dispersed and blended into said hydrophilic composition to form a medicament-containing hydrophilic composition, and particles of said medicament-containing hydrophilic composition being dispersed in said binding composition, wherein a portion of said medicament-containing hydrophilic composition particles is capable of being exposed to an outside surface of said binding composition by dissolution, separation or decomposition of said medicament-containing hydrophilic composition particles by absorption of a water-containing liquid, to release said medicament from said portion of said medicament-containing hydrophilic composition particles.
