Examples include ivacaftor, lumacaftor/ivacaftor, tezacaftor/ivacaftor, and elexacaftor/tezacaftor/ivacaftor. By improving the function of the CFTR protein, these medications help reduce mucus thickness and improve lung function.
2. Mucolytics
Mucolytics such as dornase alfa thin the thick mucus, making it easier to clear from the lungs. This can reduce lung infections and improve breathing.
3. Antibiotics
People with CF frequently encounter lung infections. Antibiotics – oral, inhaled, or intravenous – are vital for treating and preventing these infections. Common antibiotics include tobramycin, azithromycin, and ciprofloxacin.
4. Bronchodilators
These medications help open the airways and improve airflow. Albuterol is a commonly prescribed bronchodilator for CF patients.
5. Pancreatic Enzymes
Since CF affects digestion, pancreatic enzyme supplements assist in breaking down food and absorbing nutrients properly.
