Abstract
Environmentally-acceptable intimate mixtures of active ingredients and excipients which meet economic performance levels are prepared without use of harmful solvents by solubilizing and mixing the components in liquid carbon dioxide maintained under pressure and then slowly reducing the pressure to convert the carbon dioxide to the gaseous phase and venting the gaseous carbon dioxide.
