Vibrating mesh nebulizers are recognized as the most efficient actuation technique over conventional inhalers for drug deposition. This study explored hyaluronic acid (HA) decorated, ferulic acid (FA) loaded chitosan (CS) nanoparticle (FACHA) aerosolized using vibrating mesh nebulizer as strategic combination of drug, nanocarrier and delivery device for effective asthma control. FACHA exhibited spherical morphology with suitable size (164.2 ± 9.7 nm), zeta potential (24.0 ± 0.5 mV), entrapment efficiency (EE%) (65.0 ± 1.5), loading capacity (LC%) (18.5 ± 0.4) and mass median aerodynamic diameter (MMAD) of 1.81 ± 0.15 µm, ascertaining efficient drug deposition. In vivo inhalation toxicity assessment confirmed safety, while, FACHA prophylaxis mitigated inflammation, airway hypersensitivity and remodelling in ovalbumin (OVA) induced mice models. The results thus accentuated the role of pro-pulmonary surface chemistry conferred by HA functionalization that improved 1) thermal stability (thermogravimetric analysis - TGA) and 2) therapeutic efficacy of FA, by facilitating better interaction and transportation across mucus barrier, which otherwise suffers poor bioavailability and rapid metabolism.
