摘要:
An aqueous formulation for topical application to the skin comprising water, a water-miscible organic solvent, and benzoyl peroxide, wherein the concentration of the organic solvent is sufficient to provide a stable suspension of benzoyl peroxide in the aqueous formulation without the inclusion of a surfactant in the formulation, wherein the ratio of concentrations of water and organic solvent in the formulation is sufficient to maintain the benzoyl peroxide in saturated solubility in the formulation following application to the skin, and wherein the concentration of benzoyl peroxide in the formulation is less than 5.0% and at least 1.0% w/w. The formulation may further contain a chemical compound in addition to benzoyl peroxide that is effective in the treatment of acne. The aqueous formulations of the invention are useful in the treatment of acne and acne rosacea.

An aqueous solution of metronidazole in which the concentration of metronidazole is higher than 0.7%. The solution contains a combination of solubility-enhancing agents, one of which is niacinamide. Methods of manufacture and therapeutic use of the solution are disclosed.
摘要:
An oil-in-water emulsion containing one or more alpha hydroxy acids in which the oil phase of the emulsion contains a high proportion of polar constituents. The emulsion, even at high concentrations of alpha hydroxy acid, is not irritating when applied to the skin.
摘要:
Penetration-enhancing pharmaceutical compositions for topical transepidermal and percutaneous application are disclosed which are non-irritating to the skin. These compositions are made up of a safe and effective amount of an active pharmaceutical permeant, including hydrophilic salt forms, contained in a novel penetration-enhancing vehicle comprising, (i) 1-95% w. of a cell-envelope disordering compound selected from the group consisting of oleic acid, oleyl alcohol, glycerol monoleate, glycerol dioleate, glycerol trioleate and mixtures thereof, (ii) 5-75% w., and preferably 5-49% w., of a lower alkanol selected from the group consisting of ethanol, propanol and isopropanol and mixtures thereof and (iii) 0-45% w., and preferably 1-45% w., of an inert diluent which, according to properties of the permeant used, may range from hydrophilic to hydrophobic. Water, polyethylene or polypropylene glycols and mineral oil are exemplary diluents.

摘要:
An aqueous solution comprising a chelating agent at a concentration of about 0.1-0.5%, and an antioxidant agent at a concentration of about 0.1-0.5%, wherein the pH of the solution is between about 4.5 and about 7.5 is disclosed. The aqueous solution may comprise a tetracycline composition wherein the tetracycline is formulated in the aqueous solution. A method for reducing the rate and/or overall extent of degradation of a tetracycline in aqueous solution, comprising admixing in a tetracycline containing solution a chelating agent at a concentration of about 0.1-0.5% and an antioxidant at a concentration of about 0.1-0.5% and, as necessary, adjusting the pH of the solution so that it is between about 4.5 and about 7.5 is also disclosed. Tetracycline compositions of the invention may be used to treat inflammatory and/or tissue degeneration conditions.

摘要:
A transdermal drug delivery device comprising a drug formulation-containing reservoir defined by a backing layer and a drug-permeable membrane layer, a peelable inner liner that underlies the reservoir and a portion of the backing/membrane outwardly of the reservoir periphery, an adhesive layer that underlies the inner liner and outwardly extending portions of the membrane/backing layers, and a peelable release liner layer that underlies the adhesive layer with a first permanent heat seal between the backing and the membrane about the perimeter of the reservoir and another concentric peelable (impermanent) heat seal between the membrane and the inner liner positioned underlying and at a radius not less than the first permanent heat seal, the heat seals and peelable barrier layer providing barriers that isolate the drug formulation from the adhesive.
