ABSTRACT:
Methods for preparing dry powders having hydrophobic and hydrophilic components comprise combining solutions or suspensions of the components and spray drying them simultaneously in a spray drier. Both the hydrophobic and hydrophilic component are dissolved in a solvent system selected to have adequate solubility for both components. The method provides dry powders having relatively uniform characteristics.
