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).
