Title (EN) IN-SITU MULTILAYERED TABLET TECHNOLOGY
(FR) TECHNOLOGIE DE COMPRIMÉ MULTICOUCHE IN SITU
Abstract:
(EN) The present invention relates to an in-situ multilayered tablet comprising at least one polymer layers and at least one drug layers wherein the said layers are physically separated from each other. After coming in contact with biological and/or aqueous fluids at least one of the polymer layers rapidly swells and sticks to one or more drug layers to form an in-situ multilayered tablet. Further, the polymer layer may optionally comprise a drug. Furthermore, the present invention relates to the processes for preparing said in-situ multilayered tablets.
(FR) La présente invention concerne un comprimé multicouche in-situ qui comprend au moins une couche de polymère et au moins une couche de médicament, lesdites couches étant physiquement séparées l'une des l'autre. Après avoir été mise en contact avec des liquides biologiques et/ou aqueux, au moins l'une des couches de polymère gonfle rapidement et se colle à une ou plusieurs couches de médicament afin de former un comprimé multicouche in situ. En outre, la couche de polymère peut éventuellement comprendre un médicament. En outre, la présente invention concerne les procédés de préparation desdits comprimés multicouches in-situ.
