Medications Human DNase Human DNase, also known as recombinant human deoxyribonuclease (rhDNase) or dornase alfa, is a new therapy that loosens the mucus in the lungs. It works by cleaving the DNA in the airway's secretions, making it less viscous and easier to clear. RhDNase is administered daily, usually in aerosol form. It's an expensive therapy and at this time is considered only a supplemental, experimental therapy for patients with moderate to severe disease.
