Abstract

A method of making active pharmaceutical ingredient particles with surface-modified nanoparticles deposited on the particles' surfaces, the method comprising: providing a plurality of media particles having surfaces with the surface-modified nanoparticles deposited on the surfaces; mixing the plurality of media particles with the active ingredient particles, both of which are in dry form, to provide active ingredient particles having surfaces with the surface-modified nanoparticles deposited on the surfaces; and separating the plurality of media particles from the active ingredient particles having surfaces with the surface-modified nanoparticles deposited on the surfaces is disclosed.
