A method for producing orally administered, solid pharmaceutical products with controlled release of the active substance, whereby at least three of four tabletting compositions containing an active substance or a combination of active substances, variable in choice and number, are processed into solid pharmaceutical products at low cost in terms of equipment and time. By this method are produced orally administered, solid pharmaceutical products capable of providing a wide variety of pharmaceutically required release profiles for active substances or combinations of active substances, for example delayed release, uniformly sustained release or release adapted to special rhythms (pulsatile release).

L'invention concerne un procédé pour produire des formes galéniques solides pouvant être administrées par voie orale, à libération de principe actif contrôlée. Selon ce procédé, il est possible de modifier le choix et le nombre d'au moins trois formes compactées sur quatre contenant un principe actif ou une combinaison de principes actifs, ces formes compactées pouvant être transformées en formes galéniques solides selon des procédés connus, nécessitant un faible investissement en appareillage et en temps. Le procédé selon l'invention permet de produire des formes galéniques solides pour administration par voie orale, qui présentent les caractéristiques de libération de principe actif ou de combinaison de principes actifs, les plus variées, requises sur le plan pharmaceutique, par exemple une libération retardée, constante ou adaptée à des rythmes spéciaux (pulsatile).
