Pirfenidone is a prescription medicine that is used to treat idiopathic pulmonary fibrosis (IPF), which is a progressive lung disease. It works by reducing inflammation and scarring in the lungs. Pirfenidone is sometimes sold under the brand name Esbriet.
Uses
Pirfenidone is used to treat IPF, a disease that causes the lungs to become scarred and stiff over time. When this happens, it becomes harder for air to flow into and out of the lungs, which can cause shortness of breath, coughing, and fatigue. Pirfenidone helps slow down the progression of IPF by reducing inflammation and scarring in the lungs.
Benefits
The benefits of pirfenidone are significant for people with IPF. Studies have shown that it can help slow down the progression of the disease, which can improve breathing and increase quality of life. In clinical trials, participants who took pirfenidone had better lung function, fewer hospitalizations, and an increased ability to perform daily activities than those who did not take the medication.

As with all medications, pirfenidone can cause side effects. The most common side effects include:
- Nausea
