What is Nintedanib?
Simply put, Nintedanib is a medicine that stops scarring from forming in your lung tissues and slows down how fast the scarring spreads. Doctors mainly prescribe this medicine for specific lung conditions that make breathing difficult over time.
- Idiopathic Pulmonary Fibrosis (IPF): This is a lung disease where the cause is unknown, and your lung tissue slowly becomes thick and scarred.
- Chronic progressive fibrosing interstitial lung diseases: This group of long-term conditions causes ongoing scarring in the lungs.
- Systemic sclerosis-associated interstitial lung disease: Doctors also use this medicine for lung problems linked to systemic sclerosis.
This medicine does not cure your lung condition completely. Instead, it controls the damage to your lungs caused by the disease and slows down its overall speed.
