Abstract

UNA VEZ FORMADA UNA DROGA EN MICROESFERAS MEDIANTE LA EVAPORACION DE UN DISOLVENTE O/W, SE UTILIZA UN DISOLVENTE MEZCLADO CON AL MENOS UNO INSOLUBLE EN EL AGUA Y OTRO MEZCLABLE CON EL AGUA COMO DISOLVENTE DE UNA FASE OLEOSA. PODRA AÑADIRSE AL DISOLVENTE UN ACIDO GRASO O UNA SAL DEL MISMO. LA FASE OLEOSA PUEDE CONTENER AL MENOS UN ESTER DE ACIDO GRASO DE GLICERINA Y/O AL MENOS UN ESTER DE ACIDO GRASO DE GLICOL PROPILENO, DISTINTO DEL DISOLVENTE MEZCLADO. LA FASE OLEOSA PUEDE COMPRENDER TAMBIEN EL DISOLVENTE MEZCLADO; UN ACIDO GRASO O UNA SAL DEL MISMO; Y AL MENOS UN ESTER DE ACIDO GRASO DE GLICERINA Y/O AL MENOS UN ESTER DE ACIDO GRASO DE GLICOL PROPILENO. LA DROGA RESULTANTE CONTIENE MICROESFERAS QUE CONTIENEN LA DROGA EN ALTA CONCENTRACION QUE SE LIBERA MUY DESPACIO DE LA ETAPA INICIAL DESPUES DE ADMINISTRADA.
