Abstract

Método para modificar la liberación de un agente terapéuticamente activo desde una matriz elastomérica. que comprende proporcionar un núcleo que comprende una matriz elastomérica y un agente terapéuticamente activo; sumergir el núcleo en una solución de recubrimiento de un elastómero, donde el elastómero comprende 20 - 35% en peso de un agente de relleno, calculado a partir de la cantidad total de agente de relleno y elastómero; curar el núcleo sumergido para proporcionar un núcleo recubierto. En este método, se proporciona la inmersión como un proceso continuo arrastrando el núcleo a través de la solución de recubrimiento, utilizando una velocidad de arrastre adecuada para proporcionar un espesor de recubrimiento de 5 - 100 mm; el agente de relleno se selecciona entre sílice, dióxido de titanio, sulfato de bario, carbono y las mezclas de los mismos; el elastómero comprendido en el núcleo y el elastómero comprendido en la solución de recubrimiento se seleccionan independientemente entre poli(dimetil)siloxanos, polietileno acetatos de vinilo (EVA), poliuretanos (PU), polihidroxietil-metacrilatos (PHEMA) y polimetil-metacrilatos (PMMA).Method for modifying the release of a therapeutically active agent from an elastomeric matrix. comprising providing a core comprising an elastomeric matrix and a therapeutically active agent; immersing the core in an elastomer coating solution, where the elastomer comprises 20-35% by weight of a filler, calculated from the total amount of filler and elastomer; curing the submerged core to provide a coated core. In this method, dipping is provided as a continuous process by drawing the core through the coating solution, using a suitable drag speed to provide a coating thickness of 5-100 mm; the filler is selected from silica, titanium dioxide, barium sulfate, carbon, and mixtures thereof; the elastomer comprised in the core and the elastomer comprised in the coating solution are independently selected from poly (dimethyl) siloxanes, polyethylene vinyl acetates (EVA), polyurethanes (PU), polyhydroxyethyl methacrylates (PHEMA) and polymethyl methacrylates (PMMA ).
