ABSTRACT:
Methods for preparing dry powders having hydrophobic and hydrophilic components comprise combining solutions of the components and spray drying them simultaneously in a spray dryer. The hydrophilic and hydrophobic component are separately dissolved in separate solvents and directed simultaneously through a nozzle, usually a coaxial nozzle, into the spray dryer. The method provides dry powders having relatively uniform characteristics.
