Title
(EN) A CHEMICAL CARRIER BASED ON A BETA-LIMIT DEXTRIN
(FR) SUPPORT CHIMIQUE
Abstract
(EN) A formulation, especially a pharmaceutical formulation, comprises an active agent and a carrier for the active agent, wherein the carrier comprises a &bgr;-limit dextrin. The formulation may be a bioadhesive pharmaceutical formulation in which the &bgr;-limit dextrin acts as a mucoadhesive agent. The active agent is a pharmaceutically active agent or a flavour or fragrance which is intended for delivery into the buccal cavity. A use of &bgr;-limit dextrin as a disintegrant, a dispersant, and a mucoadhesive agent is also described. Also described is a nutritional product such as an energy drink which includes &bgr;-limit dextrin as an energy source.
(FR) L'invention concerne une formulation, en particulier une formulation pharmaceutique, contenant un agent actif et un support pour l'agent actif, ledit support comprenant une dextrine $g(b)-résiduelle. Cette formulation peut être une formulation pharmaceutique bioadhésive dans laquelle la dextrine $g(b)-résiduelle agit en tant qu'agent mucoadhésif. L'agent actif est un agent actif d'un point de vue pharmaceutique ou une saveur ou un parfum destiné à être diffusé dans la cavité buccale. L'invention concerne également l'utilisation de la dextrine $g(b)-résiduelle comme désintégrant, dispersant, et agent mucoadhésif. L'invention concerne en outre un produit nutritif, par exemple une boisson énergétique contenant une dextrine $g(b)-résiduelle comme source énergétique.
