Pulmozyme is a mucolytic, which is a medicine that helps break up mucus. The active ingredient in Pulmozyme is recombinant human deoxyribonuclease I (rhDNase), which is an enzyme that targets and breaks up the DNA that makes mucus thick and sticky. The rhDNase in Pulmozyme is made from genetically engineered Chinese hamster ovary cells.
Pulmozyme is prescribed to people age 6 and over with cystic fibrosis (CF) to thin the mucus that clogs their airways, which improves lung function and helps prevent respiratory infections. Pulmozyme is also being studied as a way to maintain sinus health in people with cystic fibrosis who have had sinus surgery.
