Method for producing inhalant formulation with enhanced inhalation efficiency of pirfenidone using excipient for treatment of pulmonary disease

摘要

The present invention relates to a method for preparing an inhalation formulation for the treatment of lung diseases with improved inhalation efficiency of pirfenidone using an excipient. Since it was confirmed that the inhalation efficiency of pigs was remarkably increased, it could be usefully used as a method for preparing an inhalation formulation containing pirfenidone for the treatment of lung diseases, particularly idiopathic pulmonary fibrosis.
