Conclusions, cont.

• Since the entire nebulization and drying method is carried out at lower temperatures than in other conventional spray drying processes, it is applicable to many temperature-sensitive pharmaceuticals, vaccines, Mab and proteins.
   
• Particle formation is in thin walled drying chambers near atmospheric pressure; no high pressure autoclaves are required.
   
• The usually preferred process is continuous rather than batch; the Colorado patents claim both methods.
   
• For room temperature stable powders, dry at temperatures near room temperature.
