Dornase alfa
Based on 1 publication(s) in Google Scholar
Dornase alfa (rhDNase) is a recombinant human deoxyribonuclease I (rhDNase) that can specifically degrade extracellular DNA. Dornase alfa catalyzes the cleavage of DNA released by neutrophils in respiratory mucus, reduces sputum viscosity, thereby improving mucus clearance efficiency, reducing airway obstruction and alleviating inflammatory responses. Dornase alfa can be used to improve lung function (such as FEV_1) in cystic fibrosis (CF), reduce the risk of acute pulmonary exacerbations, and has good in vivo tolerability. Dornase alfa acts locally on the respiratory tract through aerosol inhalation, specifically improving the high viscosity of mucus caused by DNA accumulation and related respiratory symptoms.

In vitro enzyme activity assays of Dornase alfa (2.5 mg/2.5 mL; nebulized) showed that after treatment with different types of nebulizers (spray type, static type, and vibration type), there was no significant loss of enzyme activity, and the protein structure remained intact without aggregation or degradation[3].

-
Animal Model:Female BALB/c mice (7-8 weeks old), healthy murine model[3]
-
Dosage:2.5 mg/2.5 mL
-
Administration:Nebulization via four nebulizers (jet nebulizers: PARI BOY SX-red/blue nozzles; static mesh: NE-U150; vibrating mesh: NE-SM1), single administration for 1 minute after 30 seconds of pre-nebulization
-
Result:The PARI BOY SX-red nozzle jet nebulizer delivered the highest amount of dornase alfa to the lungs, correlating with its aerosol particle size (Dv(50)=2.5-3.0 μm).
