Aerosolized
evaporative precipitation into aqueous solution and spray freezing into
liquid nanostructured formulations of itraconazole as prophylaxis
significantly improved survival relative to commercial itraconazole
oral solution and the control in a murine model of invasive pulmonary
aspergillosis. Aerosolized administration of nanostructured
formulations also achieved high lung tissue concentrations while
limiting systemic
exposure.
