COMPOSICAO OU ESTRUTURA MICROPOROSA EXPANDIDA ISOTROPICA DE DISSOLUCAO RAPIDA PARA UTILIZACAO FARMACEUTICA VETERINARIA DIETETICA ALIMENTAR OU COSMETICA E SEU PROCESSO DE PREPARACAO

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.
