Abstract

''MEMBRANA OU MATRIZ PARA CONTROLAR A VELOCIDADE DE PERMEAçãO DE FáRMACOS''. A invenção refere-se a uma membrana ou matriz para controlar a velocidade de permeação de um fármaco, em que a dita membrana ou matriz compreende uma composição elastomérica baseada em siloxano, que compreende pelo menos um elastómero e possivelmente um polímero não reticulado. A composição elastomérica compreende grupos polioxialquilênicos, e os grupos polioxialquilênicos estão presentes no elastómero ou no polímero como enxertos terminados com alcóxi das unidades de polissiloxano, ou como blocos, sendo que os ditos enxertos ou blocos estão ligados às unidades de polissiloxano por ligações silício-carbono, ou como uma mistura dessas formas. A invenção refere-se também a métodos para preparar a composição elastomérica a ser usada na dita membrana ou matriz.
