  • Publication number: 20120082632
    Abstract: A drug delivery system, formed as a tissue penetrating solution, comprising: a solvent suitable for solubilizing a non-liquid active ingredient into a solution; a diluent for diluting the solvent to optimize the solution for mammalian tissue compatibility; and a stabilizer for maintaining the solution chemically stable and substantially free from oxidation during storage for a pre-determined shelf life period.
    Type: Application

    Publication date: April 5, 2012
    Inventors: D. Howard Phillips, Steven Keough
  • Publication number: 20120076742
    Abstract: A topical drug delivery system for use as a self-medication delivery system, formed as a multi-functional hygroscopic solution comprising a non-hygroscopic first chemical penetration enhancer, a hygroscopic second chemical penetration enhancer and an anti-oxidizing dispersant mixable in solution with the first and second chemical penetration enhancers and an active pharmaceutical ingredient, said dispersant being in a weight percent of the solution of between 3% and 10% and being suitable for providing multiple secondary therapeutic effects by interaction with the active pharmaceutical ingredient to ensure substantial homogenous distribution of the selected active pharmaceutical ingredient in the solution during delivery of the solution to all areas of the mammalian tissue location and by further reducing the water activity level of the solution.

    Publication date: March 29, 2012
    Inventors: D. Howard Phillips, Steven Keough
  • Publication number: 20120070390
    Abstract: An over-the-counter (OTC) regulated therapeutic composition for self-medication use for application to wounds having a potential pathogen load, in which the composition comprises a tissue penetration enhancer comprising a Class I pharmaceutical incipient; a pharmaceutical antibiotic agent in a dosing suitable for use in an OTC listing; a hygroscopic carrier agent comprising a Class I pharmaceutical incipient suitable for mixing in solution with the tissue penetration enhancer and the antibiotic agent; and wherein the activity/water (Aw) measurement of the composition is less than the Aw measurement for a target pathogen in a tissue wound.

  • Patent number: 5109844
    Abstract: A method for stimulating a retinal ganglion cell in a retina without penetrating the retinal basement membrane at the surface of the retina comprises: (a) positioning a ganglion cell stimulating electrode on or above the retinal basement membrane; (b) providing a ground electrode in operative association with the ganglion cell stimulating electrode, with the ground electrode positioned on or above the retinal basement membrane and positioned for capturing electric current produced by the stimulating electrode; and (c) applying a voltage to said stimulating electrode sufficient to produce an electric current which penetrates the retina and produces an action potential in a retinal ganglion cell. Apparatus for practicing the foregoing method is also disclosed.
