Conclusion - Outlook<br />

� Surface roughness and particle size could be successfully<br />

affected by the vari<strong>at</strong>ion of spray <strong>drying</strong> process<br />

parameters<br />

� Outlet temper<strong>at</strong>ure was found to be an appropri<strong>at</strong>e<br />

parameter to adujust surface roughness<br />

� To study the influence of surface roughness on the<br />

respirable fraction of the active<br />

� To understand the crystalliz<strong>at</strong>ion processes of particles of<br />

different surface structure<br />
