What is dornase alfa used for?
Dornase alfa is a medicine used to help break down DNA in mucus. Clinicians most commonly associate it with treating lung disease where thick, sticky mucus is a problem, particularly cystic fibrosis.
How does dornase alfa work in the lungs?
Dornase alfa is an enzyme that targets extracellular DNA in mucus. In conditions like cystic fibrosis, DNA from inflamed cells can make mucus thicker and harder to clear. By breaking that DNA down, the mucus becomes less viscous and is easier to clear from the airways.
What forms does dornase alfa come in?
Dornase alfa is typically given as an inhaled treatment, delivered directly to the lungs so it can act on mucus in the airways.
What are key side effects patients ask about?
The most common patient concerns tend to center on breathing or throat irritation symptoms related to inhaled therapy (for example, coughing or hoarseness). Serious reactions are less common, but any medication delivered via inhalation can cause hypersensitivity in some people.
How is dornase alfa different from other cystic fibrosis inhaled therapies?
Dornase alfa is aimed specifically at reducing mucus viscosity by degrading DNA. Other inhaled cystic fibrosis medicines may instead work by relaxing airway muscles, reducing infection, or helping the lungs move mucus via different pathways. (Exact comparisons depend on which medication you’re comparing it with.)
