Abstract: front page image
(EN)Press-coated tablets comprising a core and a coating. The core contains an active substance and a colouring agent such that when the tablet is exposed to penetrating radiation the core is contrasted with the coating and is visible through the coating. The invention also relates to the use' of a colouring agent or excipient in such tablets to determine whether the core is centrally located within the core, to check the integrity of the core, and to ensure that there is no contaminating core material on or near the surface of the coating.
(FR)Doubles comprimés comprenant un noyau et un enrobage. Le noyau contient une substance active et un colorant, de telle sorte que, lorsque le comprimé est exposé à un rayonnement pénétrant, le noyau contraste avec l'enrobage et est visible à travers ce dernier. L'invention se rapporte également à l'utilisation d'un excipient ou d'un colorant dans de tels comprimés pour déterminer si le noyau est centré à l'intérieur de l'enrobage, contrôler l'intégrité du noyau et vérifier si de la matière contaminante issue du noyau ne se trouve pas sur ou à proximité de la surface de l'enrobage.
