Abstract
En el presente trabajo se estudia la infiuencia que los agentes tensioactivos ejercen sobre la velocidad de disolución de comprimidos, y por tanto sobre su disponibilidad "in vitro". Para ello se han elaborado sIete series de comprimidos de fenilbutazona en los que se han incluido Tween 80 Y Lauril sulfato sódico en diversas etapas de su fabricación. Se han sometido a ensayos de disolución utilizando un dispositivo automático de flujo continuo, y se ha observado un gran aumento de la misma, mayor en el caso del Laurilsulfato sódico, y especialmente cuando el tensioactivo va adicionado al aglutinante. La valoración cuantitativa de fenilbutazona en les comprimidos y en la disolución final permite apreciar la total liberación de la sustancia medicamentosa.
