The invention relates to a novel free-flowing powder pharmaceutical formulation for the delivery of a poorly-water-soluble drug substance that increases the solubility and bioavailability of the poorly-water soluble drug substance, as well as to a method of making the free-flowing powder pharmaceutical formulation. The invention also relates to dispersed particles that disperse instantaneously from the free-flowing powder formulation when the formulation is added to water, aqueous solvent, or organic solvent, wherein the bulk distribution of the poorly-water soluble drug substance of the free-flowing powder formulation in the dispersed particles is uniform. Such dispersed particles increase the bioavailable surface area of the poorly water-soluble drug substance and facilitate the drug substance's dissolution.
