Dornase alfa

Dornase alfa is a medication used to treat individuals with cystic fibrosis. Cystic fibrosis is a genetic disease that causes thick, sticky mucus to build up in the lungs and other organs in the body. Dornase alfa is a synthetic protein that works by breaking down the DNA found in this mucus. When the DNA is broken down, the mucus becomes less viscous and easier to clear from the lungs, improving lung function and reducing the risk of respiratory infections.
