Abstract

DICHO MEDICAMENTO ES INCORPORADO A PARTICULAS DE UN POLIMERO LIGADO EN CRUZ, EL CUAL ES DILATABLE EN AGUA PERO NO SOLUBLE, Y EL PRODUCTO OBTENIDO ES LLEVADO A CONTACTAR CON UN DISOLVENTE CAPAZ DE DILATAR EL POLIMERO. EL PRODUCTO OBTENIDO POR ESTE TRATAMIENTO ES DESPUES SECADO AL VACIO Y TIENE UN PORCENTAJE DE DISOLUCION CONSIDERABLEMENTE MAYOR QUE EL MEDICAMENTO PURO.
