  • Publication number: 20150031786
    Abstract: This invention provides processes for forming powders comprising at least one active compound and at least one carrier. The processes comprise (i) heating at least one active compound to at least its melting point or softening point; and (ii) in an extruder, combining at least the at least one active compound with at least one carrier, to form combined ingredients, and cooling the combined ingredients as they pass through the extruder, such that the combined ingredients exit the extruder at about ambient temperature in the form of a powder having particles sized so that about 95 wt % or more of the powder passes through a screen of about 8 standard U.S. mesh.
