PROCESS FOR PRODUCING NANOMETER PARTICLES BY FLUID BED SPRAY-DRYING

摘要

Nanometer particles of poorly water-soluble or substantially water-insoluble compound are produced by finely-spray-ing 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 an d nanometer sized particles (less than 3 .mu.m)) of compound.
