How Does Pulmozyme Work?Pulmozyme is a manufactured version of a naturally occurring human enzyme called deoxyribonuclease I. This enzyme breaks down deoxyribonucleic acid (DNA), particularly DNA found outside of cells. Research has shown that the fluid in the airways of people with cystic fibrosis has too much DNA, usually caused by the breakdown of cells that are fighting lung infections. This DNA causes the lung secretions (known as sputum) to become more thick, causing breathing problems. This becomes a problematic cycle, with infections causing more DNA and more DNA causing more infections.
Pulmozyme works by breaking down this extra DNA, helping to thin the sputum. This, in turn, helps to improve lung function and decrease the risk of lung infections.
