CA 2501245

The invention concerns a method for producing solid galenic formulations which consists in: forming a processable paste comprising a) 50 to 99.4 wt. % of at least one non-thermoplastic carrier, b) 0.5 to 30 wt. % of at least an adjuvant selected among thermoplastic polymers, lipids, sugar alcohols and solubilizing agents, c) 0.1 to 49.5 wt. % of at least one active principle, at a temperature not less than the softening temperature of the adjuvant but rising to at least 70 ~C; then in cooling the resulting paste. Said solid galenic formulations quickly disintegrate in an aqueous medium.

L'invention concerne un procédé de production de formes galéniques solides, consistant : à former une pâte façonnable comprenant a) 50 à 99,4 % en poids d'au moins un excipient non thermoplastique, b) 0,5 à 30 % en poids d'au moins un adjuvant sélectionné entre des polymères thermoplastiques, lipides, alcools de sucre, dérivés d'alcools de sucre et des solubilisateurs, et c) 0,1 à 49,5 % en poids d'au moins un principe actif, à une température égale ou supérieure au point de ramollissement de l'adjuvant mais s'élevant à au moins 70 ·C ; puis à refroidir la pâte obtenue. Ces formes galéniques solides se désagrègent rapidement dans un milieu aqueux.
