The objective of the present work was to check an Aerosol Dispersion Performance of Terbutaline Sulphate and
Itraconazole Nanoparticles as Dry Powder Insufflation for the treatment of Asthma. Dry powder nanoparticles of
Terbutaline Sulphate and Itraconazole were aimed to develop using lactose and trehalose as carriers by physical
mixing and spray drying. In this work spray dried nanoparticles containing Terbutaline Sulphate, Itraconazole and
combination of both was rationally designed via organic solution advanced spray drying (no water) in closed mode
from dilute feed concentration. It was observed that Scanning electron microscopy showed smooth and nearly
spherical particles for spray dried formulations whereas formulations prepared through milling were found to have
rough and irregular in shape. The Mean Median Aerodynamic Diameter (MMAD) values for milled systems decreased
when compared to unmilled systems. For all physically mixed systems, the MMAD values ranges from 3.19 µm to 4.78
µm whereas the Geometric Standard Deviation (GSD) values were 1.50–2.96 µm. MMAD values for spray dried
formulations ranges from 3.45 µm to 4.21 µm whereas the GSD values were 1.85–2.83 µm. These results concluded
that, this novel dry powder inhaler has great potential in treatment of asthma.
