  • Patent number: 5976555
    Abstract: Skin care compositions comprising an oil-in-water emulsion base containing retinoids and possessing good physical and chemical stability. More particularly, said skin care compositions contain (a) an emulsifier system selected from the group consisting of: (i) a mixture of glyceryl stearate and polyethylene glycol 100 stearate; (ii) cetearyl alcohol and cetearyl glucoside; (iii) a mixture of a polyethylene glycol ethers of stearyl alcohol; and (iv) a mixture of sorbitan stearate and polysorbate 60; (b) a co-emulsifier selected from the group consisting of cetyl alcohol, stearyl alcohol and mixtures thereof; (c) an oil phase present in the amount of from about 5 to about 20 percent by weight of the total emulsion composition which contains (i) a light, dry absorbable oil and (ii) substantive, emollient oils or waxes, wherein the light, dry absorbable oil and the substantive oil or wax are present in a ratio of from about 1:3 for about 10:1.

  • Patent number: 5961482
    Abstract: This invention relates to development of an iontotherapeutic device for regulated transdermal systemic administration of ionizable pharmaceutical compounds. It also provides an iontotherapeutic process for transdermal administration of ionized pharmaceuticals, particularly those which are otherwise transdermally absorbed to a small degree or not all, such as peptide pharmaceuticals, for example, insulins. The invention also relates to unit dose forms, for example, those in which an ionized pharmaceutical is dispersed in a hydrophilic polymer. The unit dose is adapted to be assembled as part of the pharmaceutical reservoir electrode, so that the ionized pharmaceutical will be delivered transdermally and then be absorbed systemically when the iontotherapeutic device is in operation.

  • Patent number: 5696164
    Abstract: There is disclosed a method for the treatment of fungal diseases in nails, which comprises the topical administration to the nail and, if desired, also to the surrounding skin, of (1) a sulfhydryl containing amino acid or a derivative thereof, the pharmaceutically acceptable salts or esters thereof, or stereoisomers thereof, (2) urea, (1) and (2) being administered in an amount sufficient to enhance the permeation of antifungal drugs through nail tissue, either prior to or, preferably, concurrently with the topical administration to the nail of (3) an effective amount of an antifungal drug.

  • Patent number: 5456851
    Abstract: A shampoo that contains ketoconazole, a surfactant, a foaming agent, thickener sufficient to give the final formulation a viscosity in the range of about 4,000 to about 9,000 cps at room temperature (i.e., about 20.degree.-25.degree. C.), preservative, butylated hydroxytoluene or butylated hydroxyanisole in an amount sufficient to retard degradation of the ketoconazole, and acid, base or buffer sufficient to give the final composition a pH in the range of from about 4 to about 10.
