Method for the production of commercial nanoparticle and micro particle powders

Abstract

The present invention relates to methods for producing nanoparticle and microparticle powders of a biologically active material which have improved powder handling properties making the powders suitable for commercial use using dry milling processes as well as compositions comprising such materials, medicaments produced using said biologically active materials in particulate form and/or compositions, and to methods of treatment of an animal, including man, using a therapeutically effective amount of said biologically active materials administered by way of said medicaments.

1 . A method for producing nanoparticle and/or microparticle biologically active material with powder handling characteristics superior to powders made by conventional size reduction processes, wherein the said method comprises the steps of:
 dry milling a solid biologically active material and a millable grinding matrix in a mill comprising a plurality of milling bodies, for a time period sufficient to produce particles of the biologically active material dispersed in an at least partially milled grinding material.
