Title (EN) MULTIPARTICULATE SUSTAINED RELEASE MATRIX SYSTEM
(FR) SYSTEME DE MATRICE A EFFET RETARD ET PARTICULES MULTIPLES
Abstract: front page image
(EN)The present invention relates to an oral dosage system of pharmacologically active substances consisting of different small tablets, each having a prolonged and controlled release, filled into hard gelatin capsules. Specifically the small tablets have a hydrophilic matrix made of xanthan gum, alone or mixed with other hydrophilic polymers, by which the slow release of the drug along the gastro-intestinal tract is obtained.
(FR)L'invention se rapporte à un système de dosage oral de substances efficaces en pharmacologie et constituées par différents petits comprimés à diffusion prolongée et contrôlée, introduits dans des capsules en gélatine dure. Spécifiquement, ces petits comprimés possèdent une matrice hydrophile en gomme de xanthane, seule ou mélangée à d'autres polymères hydrophiles, au moyen desquels la substance médicamenteuse se libère lentement dans l'appareil gastro-intestinal.
