  • 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.

  • Patent number: 5962012
    Abstract: Scopolamine is a folksy cholinergic antagonist, and is used by parasympathetic nerves in autonomic nervous neurons as an anti-motion sickness drug or an anti-emesis drug. Since the human body most effectively absorbs this drug through the postauricular skin, the drug is administered by postauricular transdermal resorption patch. The penetrability of drug is increase by adding a dermal penetrative enhancer, because the penetration ability of patch-administered drugs is usually decreased by the penetrative blockade at dermal horny layers. The present invention discloses a penetration enhancer to increase dermal absorption and penetration of the cholinergic antagonist. The present invention finds that polyethylene and amide enhance penetration, about 2.2-2.8 fold. In accordance with the present invention, a penetration enhancer is added to the formulations of transdermal patch to increase the human body's absorption of scopolamine.

  • Patent number: 5958383
    Abstract: A lotion such as a sunscreen includes a color indicator which colorizes the lotion until the lotion is applied to human skin, whereinafter the colored lotion changes color or turns clear. A physiological color indicator such as a pH indicator, a colorant, or a water-soluble dye such as coumarin can be used, alone or in combination, to colorize the lotion in accord with the invention. The lotion is suitable for use in any lotion, gel, mousse or medication that is best applied in an even and uniform manner to the skin. Accordingly, one preferred use of the invention is in UV-protection sunscreens so that a user can ensure even distribution of the sunscreen on the body. A sunscreen of the invention can also include an emollient, such as jacoba oil, an emulsifier, a surfactant, such as sorbitol, water, and a pH adjuster, such as triethanolamine.

  • Patent number: 5958427
    Abstract: The invention is directed to nitric oxide (NO) donor compounds and to pharmaceutical compositions containing such nitric oxide (NO) donor compounds, for delivering NO to the apical surface of a mucosa, where the nitric oxide is released for passage across the epithelial monolayer of the mucous membrane. The NO donor compounds include polyalkyleneamine NO donors as well as tertiary and quaternary amino aliphatic NO donor compounds. The compounds and compositions of the invention are useful in any situation in which it is desirable to deliver NO across a mucosal surface. For example, the compounds and compositions of the invention are particularly useful in treating pulmonary hypertension, male impotence, and several other specific conditions.

  • Patent number: 5955062
    Abstract: A lotion such as a sunscreen includes a pH indicator which colorizes the lotion until the lotion is applied to the human skin, whereinafter the colored lotion turns clear. A physiologically compatible pH indicator such as phenolphthalein is used which has a red appearance from pH 7.5+ and which has a clear appearance from about pH 7.0 to 7.5, the general pH range of the skin. The invention is suitable for use in any lotion, gel, mousse or medication that is best applied in an even and uniform manner to the skin. Accordingly, one preferred use of the invention is in UV-protecting sunscreens so that a user can ensure even distribution of the sunscreen on the body. In certain aspects of the invention, a cap houses the pH indicator and attaches to a container of the lotion, e.g., a sunscreen. The pH indicator mixes with the lotion as it is applied to the skin.

    Abstract: A lotion such as a sunscreen includes a pH indicator which colorizes the lotion until the lotion is applied to the human skin, whereinafter the colored lotion turns clear. A physiologically compatible pH indicator such as phenolphthalein is used which has a red appearance from pH 7.5+ and which has a clear appearance from about pH 7.0 to 7.5, the general pH range of the skin. The invention is suitable for use in any lotion, gel, mousse or medication that is best applied in an even and uniform manner to the skin. Accordingly, one preferred use of the invention is in UV-protecting sunscreens so that a user can ensure even distribution of the sunscreen on the body. In certain aspects of the invention, a cap houses the pH indicator and attaches to a container of the lotion, e.g., a sunscreen. The pH indicator mixes with the lotion as it is applied to the skin.

  • Patent number: 5716928
    Abstract: A method for increasing bioavailability and reducing inter- and intra-individual variability of an orally administered hydrophobic pharmaceutical compound, which comprises orally administering the pharmaceutical compound to a mammal in need of treatment with the compound concurrently with an essential oil or essential oil component in an amount sufficient to provide bioavailability of the compound in the presence of the essential oil or essential oil component greater than bioavailability of the compound in the absence of the essential oil or essential oil component, wherein the essential oil or essential oil component has an activity of at least 10% inhibition at a concentration of 0.01 wt. % or less in an assay that measures conversion of cyclosporine to hydroxylated products using an assay system containing 250/.mu.g rat liver microsomes, 1.mu.M cyclosporine, and 1 mM reduced nicotinamide adenine dinucleotide phosphate (NADPH) in 1 ml of 0.1M sodium phosphate buffer, pH 7.4.
