Abstract

LATICES POLIMERICOS LIOFILIZADOS, QUE PUEDEN RECONSTITUIRSE EN AGUA PARA CONSEGUIR DISPERSIONES POLIMERICAS ACUOSAS CON UN ALTO CONTENIDO SOLIDO DE POLIMEROS. LAS DISPERSIONES POLIMERICAS RECONSTITUIDAS RESULTAN DE GRAN UTILIDAD EN LA PREPARACION DE FORMULACIONES FARMACEUTICAS DE DISTRIBUCION SOSTENIDA, EN PARTICULAR, DE FARMACOS SOLUBLES EN AGUA, MEDIANTE EL METODO DE GRANULACION HUMEDA SIN EXCESO DE HUMEDAD.
