Patent

CA 2521624

Disclosed are controlled release dosage forms of pharmaceutical or nutritional agents that are intended for retention in a buccal or sublingual location for administration. The dosage forms are particularly useful for the sustained release administration of drugs that have a limited window of absorption in the gastrointestinal tract and that are minimally, if at all, absorbed nucosally.

La présente invention concerne des formes posologiques à libération contrôlée de principes actifs ou d'agents nutritifs, ces formes posologiques étant conçues pour administration avec rétention buccale ou sublinguale. Ces formes posologiques conviennent particulièrement pour une administration à libération prolongée de médicaments dont la fenêtre d'absorption par voie gastro-intestinale est limitée, et qui ne sont, le cas échéant, que très peu absorbés par les muqueuses.
