  • Patent number: 5132114
    Abstract: Compositions and methods of manufacture for producing a medicament composition capable of absorption through the mucosal tissues of the mouth, pharynx, and esophagus. The present invention relates to such compositions and methods which are useful in administering drugs in a dose-to-effect manner such that sufficient drug is administered to produce precisely a desired effect. The invention also relates to a manufacturing technique that enables a therapeutic agent or drug to be incorporated into a flavored confectionary base and to compress or otherwise attach the solid confectionary mixture onto an appliance or holder.Employing the present invention the drug may be introduced into the patient's bloodstream almost as fast as through injection, and much faster than using the oral administration route, while avoiding the negative aspects of both of these methods. The present invention achieves these advantages by incorporating the drug into a compressed powder "candy" matrix.

  • Patent number: 5104661
    Abstract: The first part explains the discovery, and means to employ the discovery that whole, intact vesicles and liposomes are not the sole means of burden (drug) delivery by targeting molecules. The second part teaches the discovery of reverse loading of vesicles and liposomes to obtain fully functional core volume load of a useful burden without the trauma degradation of the active burden material, and with greatly extended shelf life.

  • Patent number: 5098712
    Abstract: The present invention concerns synthetic mica powder containing from 75 to 99% of the stoichiometrical composition of fluorine and/or having a shape in which the end face of a particle is laminated, a process for producing such synthetic mica powder, as well as cosmetics having synthetic mica powder blended therewith, in which the synthetic mica powder shows no leaching of fluorine ions and/or improved hold of oils due to lamination at the surface of the powder. Accordingly, in this invention, cosmetics excellent in extensibility, gloss, adherence and moldability, having an appearance of high chroma and of high stability and safety can be obtained.

  • Patent number: 5089256
    Abstract: The process for the preparation of containers comprising two or more partial regions separated from each other of solid cast powder formulations having different colors employs containers into which separating bridges of a pasty composition have been injected, said composition being similar to the subsequently cast solid powder formulations. The bridges prevent the partial regions having different colors from coalescing.

  • Patent number: 5049388
    Abstract: Disclosed are aqueous aerosol droplets containing liposome or interacted liposome-drug or medication combination particles in a continuous phase of air or oxygen-enriched air advantageous for the treatment of a wide variety of diseases. The drug or medication is interacted with the liposome membrane so that on its rupture the drug or medication is not lost from the liposome. Different methods of preparation of the aerosol particles containing the liposome and interacted liposome-drug combination particles are described which can be used in small particle aerosol treatment. The majority of the aerosol droplets containing the liposome particles alone or with drugs has a diameter less than 5 microns and has an aerodynamic mass median diameter ranging from about 1 to 3 microns, and the liposome and interacted-liposome drug particles are substantially uniform in size and less than 1 micron in diameter.
