Pirfenidone axunio (previously Pirfenidone AET)

Pirfenidone axunio is a medicine used to treat adults with mild to moderate idiopathic pulmonary fibrosis (IPF). IPF is a long-term disease in which fibrous scar tissue continuously forms in the lungs, causing persistent cough, frequent lung infections and severe shortness of breath. ‘Idiopathic’ means that the cause of the disease is unknown. Pirfenidone AET is a ‘generic medicine’. This means that Pirfenidone AET contains the same active substance and works in the same way as a ‘reference medicine’ already authorised in the EU called Esbriet. For more information on generic medicines, see the question-and-answer document [here](https://www.ema.europa.eu/en/documents/medicine-qa/questions-answers-generic-medicines_en.pdf). Pirfenidone AET contains the active substance pirfenidone.
