  • Patent number: 5466440
    Abstract: Nanoparticulate crystalline substances formulated with stabilizers and pharmaceutically acceptable clays to enhance contact between the crystalline substances and the gastrointestinal tract. These formulations have improved safety profiles, a low potential for absorption, are not viscous and are not contraindicated for GI perforations or intestinal obstructions. The properties of the surfactant stabilizers are independent of the crystalline drug used and largely determine the extent to which the formulation coats the GI tract.
