Vibrating mesh nebulizers (VMN) demonstrate improved efficiency for delivery of inhaled aerosol solutions or suspensions as compared to compressor devices. The added advantages of compactness, portability and functioning as noise-free device makes them of incremental value in Home or Ambulatory settings while managing Severe Obstructive airway disease or delivery of maintenance medications in these cases. This further circumvents the need for multiple devices thereby further improving patient compliance and convenience while delivering acute or maintenance formulations including Glycopyrronium (GLY) and Formoterol (FRM)/Budesonide(BUD) nebulizing solution formulations. To further assess the clinical role and feasibility of FRM-BUD formulation delivery kinetics with or without GLY nebulizing solution through VMN and jet nebulizers for In- & outpatient settings, 2 comparative in-vitro lung deposition studies were carried out utilizing Anderson Cascade impactor at 30 L/min; with deposited drug estimated by HPLC. Post-hoc analyses with p<0.05 were considered statistically significant for intergroup differences on FRM/BUD and GLY delivered through VMN or Compressor devices. The calculated mean fine particle dose for FRM & BUD delivered by VMN or jet nebulizer showed no statistical difference. However the mean fine particle fraction for BUD delivered by VMN was significantly better compared to jet nebulizer. The Residual volume at 10 mins was significantly higher with jet nebulizer. The optimal Aerodynamic Particle Size Distribution (APSD) for GLY nebulizing solution admixture with FRM/BUD suspension delivered through VMN and Jet nebulizer offers a clinically relevant strategy for High risk COPD cases in Acute or Home settings.
