Defective CFTR | Upregulate function | Pharmacological agents |
Abnormal ion transport | Increase chloride transport | UTP/ATP |
| Block sodium uptake | Amiloride |
Thick obstructive mucus | Decrease viscosity | Mucolytics |
| | DNAse |
Impaired clearance | Augment clearance | Chest physiotherapy |
Pulmonary infection | Decrease bacterial load | Antibiotics |
| | Salt-insensitive antimicrobial peptides |
Pulmonary inflammation | Diminish host reaction | Antiprotease |
Bronchiectasis | Replace when irreversible damage | Lung transplant |
