Abstract

SE DESCRIBE UN SISTEMA DE LIBERACION CONTROLADA BIODEGRADABLE MEJORADA, QUE CONSTA DE UNA MATRIZ POLIMERICA QUE INCORPORA UN ANESTESICO LOCAL PARA LA ADMINISTRACION PROLONGADA DEL AGENTE ANESTESICO LOCAL Y UN METODO PARA LA FABRICACION DEL MISMO. LOS POLIMEROS Y EL METODO DE FABRICACION USADOS PARA FORMAR LOS PLAM SON SELECCIONADOS SOBRE LA BASE DE SUS PERFILES DE DEGRADACION: LIBERACION DEL ANESTESICO TOPICO DE UNA MANERA LINEAL, CONTROLADA DURANTE UN PERIODO DE DOS SEMANAS CON PREFERENCIA Y DEGRADACION IN VIVO CON UNA VIDA MEDIA DE MENOS DE SEIS MESES, CON MAS PREFERENCIA DOS MESES, PARA EVITAR INFLAMACION LOCALIZADA. DE MODO ALTERNATIVO, PUEDE SER INCORPORADO UN ANTIINFLAMATORIO EN EL POLIMERO CON EL ANESTESICO LOCAL PARA PREVENIR LA INFLAMACION.
