| Abstract |
Idiopathic pulmonary fibrosis is a chronic lung disease that is characterized by progressive abnormal reprogramming following injury of the pulmonary structure. In this study, we prepared a nintedanib (antifibrotic agent) and cyclodextrin (CyD) inclusion complex to improve the pharmacokinetics and antifibrotic effects of nintedanib following intrapulmonary administration. Hydroxypropyl-γ-CyD (HP-γ-CyD) enhanced the solubility of nintedanib without cytotoxic effects on WI-38 cells (lung fibroblasts) and NCI-H441 cells (alveolar epithelium model). Compared with nintedanib ethanesulfonate salt, the nintedanib-HP-γ-CyD inclusion complex exhibited prolonged distribution in the lungs following intrapulmonary administration in mice with bleomycin-induced pulmonary fibrosis. In addition, compared with nintedanib ethanesulfonate salt, the nintedanib-HP-γ-CyD inclusion complex exhibited higher stability in the bronchoalveolar lavage fluid and lower permeability in NCI-H441 cell monolayers. These results suggested that the inclusion complexation of nintedanib into HP-γ-CyD improved its pharmacokinetics following intrapulmonary administration by increasing its stability in the lungs and reducing its permeability through the alveolar cell membrane. Intrapulmonary administration of the nintedanib-HP-γ-CyD inclusion complex significantly reduced the intrapulmonary hydroxyproline content and limited pathological fibrotic changes. Overall, this study indicates that antifibrotic agent-CyD inclusion complexation intended for intrapulmonary administration can be used to prolong distribution in the lungs and lead to the expansion of idiopathic pulmonary fibrosis therapy.
