Effect of granulocyte colony-stimulating factor combination therapy on efficacy of posaconazole (SCH56592) in an inhalation model of murine pulmonary aspergillosis

Using an inhalation model of pulmonary aspergillosis, we observed modest differences in the survival rates of mice treated with granulocyte colony-stimulating factor (G-CSF) and posaconazole (POS) and those treated with POS alone. This finding is in contrast to a previous report that suggested that G-CSF had a significant antagonistic effect on the antifungal activity of POS.
