High (greater than 30%) and/or low (less than 10%) loaded multiple API powdered/nanoparticle were tabulated with increased flowability and physical properties. Properties include blend flowability and uniformity, bulk packing density, compactability, tensile strength, and dissolution. Blending is done through solventless dry mechanical coating of at least one minority API component defined as the API component with the least weight per volume surface coated with nano-sized powders in lesser amounts by wt % of the blend, and preferably less than 10% dry coated of the minority API. An excipient may be dry coated in the lesser amount wherein the excipient is a minority component. Both minority excipient and minority API may be dry coated. Using dry coating instead of dry granulation and/or wet granulation techniques in producing tablets saves manufacturing steps, costs, and produces higher quality tablets with surprisingly higher properties than expected for low flowability solid powdered ingredients.
