Abstract

Se describe una microemulsion de aceite-en-agua o bicontinua, no toxica, como un vehículo para la administracion de uno o más compuestos activos que tienen baja solubilidad en agua, donde la microemulsion contiene: una fase polar que contiene agua y, opcionalmente, un agente para obtener condiciones isotonicas, y uno o más componentes (modificadores) para ajustar la polaridad de la fase polar; un modificador de la película del surfactante, una fase no polar que consiste de al menos un aceite farmacéuticamente aceptable; y una mezcla de un surfactante hidrofílico y un surfactante hidrofobico hasta un 15%, en peso, de la microemulsion total, donde el surfactante hidrofobico se elige de un grupo que consiste de lecitina, esfingolípidos o galacto lípidos.
