Nanometer particles of poorly water-soluble or substantially water-insoluble compound are produced by finely-spraying a non-aqueous solution of said compound into a heated and fluidized bed of carrier excipient. The resulting product consists of a free flowing mixture of relatively large particles of carrier excipient and nanometer sized particles (less than 3 &mgr;m)) of compound.
