  • Patent number: 9452145
    Abstract: A drug-containing patch allows transdermal administration of a drug. The patch features a hydrophobic reservoir containing the drug, where the reservoir has a first surface and a second surface. A drug-impermeable backing overlies the first surface of the reservoir. A release sheet may overlie the second surface of the reservoir. The hydrophobic reservoir contains a drug and a hydrophobic matrix, where the hydrophobic matrix includes a hydrophobic filler in an amount which is effective to adsorb said drug; and a mixture of polyisobutylene and mineral oil. The hydrophobic matrix may contain hydrophobic colloidal silica as the hydrophobic filler. The hydrophobic reservoir layer may serve as a skin-contacting adhesive layer. Alternatively, a release-controlling adhesive layer may serve as the skin-contacting adhesive layer. The release-controlling adhesive layer may contain hydrophobic colloidal silica and a mixture of polyisobutylene and mineral oil.

  • Publication number: 20160228463
    Abstract: This invention relates to compounds useful for treating fungal infections, more specifically topical treatment of onychomycosis and/or cutaneous fungal infections. This invention is directed to compounds that are active against fungi and have properties that allow the compound, when placed in contact with a patient, to reach the particular part of the skin, nail, hair, claw or hoof infected by the fungus. In particular the present compounds have physiochemical properties that facilitate penetration of the nail plate.

  • Patent number: 9302009
    Abstract: Methods and compositions for treating disorders of the nail and nail bed. Such compositions contain a vehicle in which all components of the composition are dissolved, suspended, dispersed, or emulsified, a non-volatile solvent, a wetting agent, and a pharmaceutically active ingredient that is soluble in the non-volatile solvent and/or a mixture of the vehicle and the non-volatile solvent, which composition has a surface tension of 40 dynes/cm or less and has continuing spreadability, and which composition is effective in treating a disorder of the nail or nail bed.
