Abstract

SE PREPARAN COMPOSICIONES DE LIPOSOMA EN LAS CUALES SE RETIENE UN MEDICAMENTO EN CONDICION ESTABLE POR DISPERSION DE LIPOSOMAS OBTENIDOS POR SEPARACION DE UN DISOLVENTE DE UNA EMULSION AÑO QUE CONTIENE EL MEDICAMENTO EN UNA DISOLUCION QUE TIEN UNA PRESION OSMOTICA MAYOR EN EL 20% POR LO MENOS QUE LA PRESION OSMOTICA DE UNA DISOLUCION UTILIZADA PARA ATRAPAR EL MEDICAMENTO EN DICHOS LIPOSOMAS. ESTA COMPOSICION DA LUGAR A UNA EFICACIA TERAPEUTICA CONTINUADA O UNA MEJOR DISTRIBUCION DEL MEDICAMENTO EN UN ORGANO OBJETIVO.
