CA 2490365

The invention provides a composition useful for making oral dosage forms capable of dissolving un the mouth in less than 40 seconds without the need for a conventional super disintegrant and having a friability of less than 1%, wherein the composition includes liquiflash particles and an excipient mass. according to the invention contains a directly compressible inorganic salt; a cellulose derivative or a combination of directly compressible inorganic salt and a cellulose derivative. Preferably,, the liquiflash particles and the excipient mass are combined in porportions such that the active ingredient remains substantially within the microspheres when the composition is compressed to obtain a dosage form having a hardness of 20 to 50 N. The compositions of the invention allow for the fabrication of oral dosages having improved hardness aand friability.

L'invention concerne une composition utile pour la fabrication de formes posologiques orales pouvant se dissoudre dans la bouche en moins de 40 secondes, sans nécessité d'employer un super disintégrant classique, et présentant une friabilité inférieure à 1 %. La composition de l'invention comprend des particules liquiflash et une masse d'un excipient. Selon l'invention, une masse d'excipient préférée contient un sel inorganique directement compressible, un dérivé de cellulose, ou une association d'un sel inorganique directement compressible et d'un dérivé de cellulose. De préférence, les particules liquiflash et la masse d'excipient sont associées dans des proportions telles qu'un ingrédient actif demeure sensiblement à l'intérieur des microsphères lorsque la composition est comprimée pour donner une forme posologique présentant une dureté de 20 à 50 N. Les compositions de l'invention permettent de produire des doses orales présentant une dureté et une friabilité améliorées.
