What is the purpose of Pulmozyme in patients with cystic fibrosis?

• A. To increase appetite
• B. To strengthen bones
• C. To make lung secretions thinner
• D. To improve vision

Answer: (C)

Pulmozyme, known generically as dornase alfa, is specifically designed to dissolve thick, sticky mucus in the lungs of individuals with cystic fibrosis. This medication works by breaking down the DNA that accumulates in the mucus, which helps to thin lung secretions. As a result, thinner secretions are easier to clear from the airways, improving lung function and helping to reduce the risk of infections and complications associated with cystic fibrosis. Its primary role is in enhancing respiratory health by facilitating easier breathing and clearing mucus, which is a significant issue for patients with this condition.
