  • Patent number: 5002935
    Abstract: Inclusion complexes of hydroxypropyl-.beta.-cyclodextrin with the reduced biooxidizable, blood-brain barrier penetrating, lipoidal forms of dihydropyridine.revreaction.pyridinium salt redox systems for brain-targeted drug delivery provide a means for stabilizing the redox systems, particularly against oxidation. The reodox inclusion complexes also provide a means for decreasing initial drug concentrations in the lungs after administration of the systems, leading to decreased toxicity. In selected instances, complexation results in substantially improved water solubility of the redox systems as well.

  • Patent number: 4812445
    Abstract: Virtually any material may be encapsulated in a starch matrix by combining the material with a high temperature-stabilized dispersion of starch, optionally in the presence of salt. The temperature-stabilized starch dispersion acts as a protective colloid, encasing the material to be encapsulated. Upon subsequent rapid cooling of this mixture on a chilled surface the starch polymer chains collapse upon themselves, forming a firm sheet or the like and encapsulating the core material. The sheet can then be cut, chopped or sliced in the wet state, then dried and ground to yield particles.
