  • Patent number: 5972317
    Abstract: A nail-permeable medication means is disclosed for delivering a medicament through nails, claws, hoofs, or other similar hardened tissue of dermal derivation. The nail-permeable medication means includes a proteolytic enzyme component which facilitates permeation of substances through the hardened nail or keratin tissue, and also includes a medicament component selected to treat a specific disease. The nail-permeable medication means is particularly useful for treating onychomycosis of the fingernail or toenail, and avoids the need for more drastic therapeutic modalities, such as removal of the nail.
    Type: Grant
    Filed: August 6, 1998
    Date of Patent: October 26, 1999
    Assignee: Sorenson Pharmaceutical, Inc.

  • Patent number: 5534260
    Abstract: A percutaneous drug delivery method and enhancement composition are disclosed. The method comprises applying an enzyme preparation containing suitable amounts of non-enzyme permeation enhancers, such as lactam compounds (e.g. 1-substituted-azacycloheptan-2-one), and propylene glycol to a localized area of skin for a predetermined amount of time to enhance that area of skin's permeability to selected drug(s); occluding the area of skin during the application; and then applying the selected drug(s) to the area of skin to allow the drug to penetrate through the skin and into the circulatory system of the animal. Greatly enhanced penetration of chemicals through the skin results from the described treatment.

  • Patent number: 4725427
    Abstract: Flavored, effervescent, water soluble compositions containing water-soluble and oil-soluble vitamins and amino acid chelated minerals in bioavailable form are contained in a composition consisting of 20-30% of a vitamin blend consisting of water-soluble and oil-soluble vitamins adsorbed on a lactose carrier containing a minor amount of propylene glycol, 5-25% of one or more amino acid chelated minerals selected from the group consisting of calcium, magnesium, iron, zinc, copper and manganese, 20-45% citric acid, 5-25% of one or more alkali or alkaline earth metal bicarbonates or carbonates, 1-5% flavoring agent, 0.5-2% of a sweetening agent and sufficient additional lactose carrier to provide the desired vitamin and mineral content per unit dosage which will normally vary between about 2 and 6 grams. When dissolved in water a flavored, lightly carbonated drink is provided which will contain in soluble bioavailable form between about 50 to 100% of the U.S.
