摘要:
The present invention relates to a method for preparing an inhalation formulation for treating pulmonary diseases with improved inhalation efficiency of pirfenidone using a wet ball mill process, adding pirfenidone to the insoluble solvent hexane of the present invention, and having a diameter of 0.9 to When a wet ball mill process was performed with a 1.1 mm ball to prepare a pirfenidone inhalation formulation, it was confirmed that the inhalation efficiency of pirfenidone was significantly increased, and thus pirfeni for the treatment of lung diseases, particularly idiopathic pulmonary fibrosis. It can be usefully used as a method for preparing an inhalation formulation containing money.본 발명은 습식 볼 밀 공정을 이용한 피르페니돈의 흡입 효율이 증진된 폐질환 치료용 흡입 제형의 제조 방법에 관한 것으로, 본 발명의 불용성 용매인 헥산에 피르페니돈을 첨가하고, 직경이 0.9~1.1mm인 볼로 습식 볼 밀 공정을 진행하여 피르페니돈 흡입 제형을 제조할 경우, 피르페니돈의 흡입 효율이 현저하게 증가된다는 것을 확인하였으므로, 폐질환, 특히 특발성 폐 섬유화증의 치료를 위한 피르페니돈을 함유하는 흡입 제형의 제조 방법으로 유용하게 사용될 수 있다.
