Title (EN) HOT MELT EXTRUDED FILM CONTAINING SILICON DIOXIDE
(FR) FILM EXTRUDÉ À CHAUD PAR COULÉE CONTENANT DU DIOXYDE DE SILICIUM
Abstract: front page image
(EN)A single or multilayered laminated hot melt extruded composition includes silicon dioxide, polyethylene oxide, at least one additional polymer, and at least one additive. A single or multilayered laminated hot melt extruded composition further includes a therapeutic agent. A method of processing a mixture into a thin film includes the steps of: forming a mixture comprising silicon dioxide, polyethylene oxide, at least one additional polymer, and at least one additive; extruding said mixture to the top of a calendering section; and winding the mixture into master rolls of thin film. A method of drug delivery includes applying to a mucosal surface a hot melt extrusion composition, wherein the extrusion composition includes a detackifier, at least one polymer, at least one additive, and a therapeutic agent.
(FR)La présente invention concerne une composition extrudée à chaud par coulée stratifiée mono ou multicouche comprenant du dioxyde de silicium, de l'oxyde de polyéthylène, au moins un polymère supplémentaire, et au moins un additif. Une composition extrudée à chaud par coulée stratifiée mono ou multicouche selon l’invention comprend en outre un agent thérapeutique. L'invention concerne en outre un procédé de traitement d'un mélange en un film mince comprenant les étapes consistant à : former un mélange comprenant du dioxyde de silicium, de l'oxyde de polyéthylène, au moins un polymère supplémentaire, et au moins un additif ; extruder ledit mélange en direction du haut d'une section de calandrage ; et enrouler le mélange en cylindres maîtres de film mince. L'invention concerne de plus un procédé d'administration de médicament comprenant l'application sur une surface muqueuse d'une composition fabriquée par extrusion à chaud par coulée, la composition d’extrusion comprenant un antiadhésif, au moins un polymère, au moins un additif, et un agent thérapeutique.
