Aerosol pirfenidone and pyridone analog compounds and uses thereof
First Claim
1. A method for the treatment of idiopathic pulmonary fibrosis in an adult human in need thereof, the method comprising:
- administering one or more respirable delivered doses per day of an aqueous solution comprising pirfenidone, by a liquid nebulizer, to the human in need thereof;
the aqueous solution comprising water and pirfenidone at a concentration from about 5.0 mg/mL to about 19 mg/mL, the aqueous solution having an osmolality of from about 50 mOsmol/kg to about 2000 mOsmol/kg, wherein the daily respirable delivered dose is at least 0.8 mg of pirfenidone;
wherein the total daily respirable delivered dosage of pirfenidone administered to the human by the liquid nebulizer does not exceed 1.933 mg/kg body mass/day, wherein the respirable delivered dose is therapeutically effective to treat IPF by reducing decline in forced vital capacity (FVC) in the lung of the adult human.
