The invention concerns a composition for pharmaceutical, veterinary, food, dietetic or cosmetic use, comprising 1 wt. % to 50 wt. % of one or several active principle(s), 50 wt. % to 90 wt. % of a carrier comprising one or several polymer(s), optionally one or several diluent(s) and optionally one or several additive(s), in particular flavouring or colouring additives. Said composition is characterised in that it has a fast-dissolving isotropic microporous expanded structure and the polymers are selected from the group consisting of polymers of plant origin, optionally combined with polymers of animal origin or synthetic polymers, and said carrier is such that the binding polymer(s) are present in the composition in a proportion not less than 1 % (p/p) and more particularly ranging between 6 % and 98 % (p/p). With respect to the polymer(s), it is a polysaccharide of plant origin, optionally modified by chemical or enzymatic process or obtained by chemical or enzymatic hydrolysis which is being particularly referred to.

La présente invention concerne une composition à usage pharmaceutique, vétérinaire, alimentaire, diététique ou cosmétique, comprenant 1 % à 50 % en poids d'un ou plusieurs principe(s) actif(s), 50 % à 99 % en poids d'un support comprenant un ou plusieurs polymères, éventuellement un ou plusieurs diluant(s) et éventuellement un ou plusieurs additif(s), notamment arôme ou colorant, ladite composition étant caractérisée en ce qu'elle présente une structure expansée microporeuse isotrope à dissolution rapide et les polymères étant choisis dans le groupe constitué par les polymères d'origine végétale, éventuellement en combinaison avec les polymères d'origne animale ou les polymères de synthèse, et ledit support étant tel que le ou les polymère(s) liants sont présents dans la composition dans une proportion supérieure ou égale à 1 % (p/p) et plus particulièrement comprise entre 6 % et 98 % (p/p). Parmi le ou les polymère(s) on entend notamment un polysaccharide d'origine végétale, éventuellement modifié chimiquement ou enzymatiquement ou obtenu par hydrolyse chimique ou enzymatique.
