PROCESSES TO GENERATE SUBMICRON PARTICLES OF WATER-INSOLUBLECOMPOUNDS

摘要

Submicron particles of water-insoluble compounds, particularly drugs, are prepared by simultaneously stabilizing microparticulate suspensions of same with surface modifier molecules by rapid expansion into an aqueous medium from a compressed solution of the compound and surface modifiers in a liquefied gas and optionally homogenizin g the aqueous suspension thus formed with a high pressure homogenizer.
