Area of Science:

  • Pharmaceutical Sciences
  • Drug Delivery Systems
  • Aerosol Science

Background:

  • Nebulized budesonide is crucial for managing respiratory conditions.
  • Optimizing budesonide delivery efficiency is essential for therapeutic efficacy.
  • Surface-active agents have the potential to modify aerosol properties.

Purpose of the Study:

  • To enhance the efficiency of nebulized budesonide formulations.
  • To investigate the impact of various detergents on budesonide aerosol characteristics.

Main Methods:

  • Commercial budesonide suspension was modified with cationic, anionic, and nonionic detergents.
  • Particle size distribution was analyzed during nebulization using cascade impaction and laser diffraction.
  • Emitted dose and respirable fraction were quantified for each formulation.

Main Results:

  • Cationic and nonionic detergents significantly increased the emitted dose of budesonide.
  • All tested detergent formulations led to a significant increase in the respirable fraction.
  • The addition of surface-active agents improved budesonide aerosol performance.

Conclusions:

  • Cationic and nonionic detergents effectively enhance the total output of nebulized budesonide.
  • Detergent formulations improve the respirable fraction, potentially increasing lung deposition.
  • Surface-active agents represent a promising strategy for optimizing budesonide nebulization.
