Abstract

METODOS PARA HACER UNA COMPOSICION FARMACEUTICA QUE CONTIENE LIPOSOMAS, CUYOS LIPOSOMAS COMPRENDEN UNA CANTIDAD TERAPEUTICAMENTE ACEPTABLE DE UNA HIDROMONOBENZOPORFIRINA FOTOSENSIBILIZADORA Y UNA MEZCLA DE FOSFOLIPIDOS QUE COMPRENDEN FOSFATIDIL GLICEROL DE HUEVO ( EPG ) Y DIMIRISTOIL FOSFATIDIL COLINA ("DMPC ). EL METODO COMPRENDE LOS SIGUIENTES PASOS: A) COMBINACION DEL FOTOSENSIBILIZADOR Y DE LOS FOSFOLIPIDOS EN UNA RELACION MOLAR DE ALREDEDOR DE 1:7,0 O MAS FOSFOLIPIDOS EN PRESENCIA DE UN DISOLVENTE ORGANICO; B) ELIMINACION DEL DISOLVENTE ORGANICO PARA FORMAR UNA PELICULA LIPIDICA; C) HIDRATACION DE LA PELICULA LIPIDICA CON UNA SOLUCION ACUOSA A UNA TEMPERATURA POR DEBAJO DE UNOS 300 (GRADOS) C, PARA FORMAR LIPOSOMAS GROSEROS QUE CONTIENEN UN COMPLEJO FOTOSENSIBILIZADORFOSFOLIPIDO; Y D) HOMOGENEIZACION O REDUCCION DE LA DIMENSION DE LAS PARTICULAS DE LOS LIPOSOMAS GROSEROS HASTA UN RANGO DE TAMAÑO DE PARTICULA DE ALREDEDOR DE 150 A 300 NM A UNA TEMPERATURA POR DEBAJO DE UNOS 300 (GRADOS)C. LA INVENCION TAMBIEN CONTEMPLA LAS COMPOSICIONES FARMACEUTICAS LIPOSOMICAS EN SI MISMAS.
