Abstract: 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.

Abstract: The present invention provides stable aqueous doxycycline aqueous solutions suitable for pharmaceutical, especially ophthalmic, use. The doxycycline aqueous solutions have a pH ranging from 4.5-8, and contain an antioxidant and a stabilizer such as caffeine, creatine or mixtures thereof. The solutions have improved lifetimes and can be used topically.

Abstract: A solid dosage form for oral administration comprising azithromycin in an amount below that which causes gastrointestinal side effects, which dosage form is a controlled release dosage form.

Abstract: Powder containing benzoyl peroxide is readily wetted by contacting the powder with a liquid containing one or more of a polyol, a polyol, ether, and a low-carbon organic alcohol.

Abstract: Azithromycin has increased efficacy in treating acne and other skin conditions when administered systemically at low doses, below those previously known to produce a clinical antibiotic effect.

Abstract: A solid dosage form for oral administration comprising azithromycin in an amount below that which causes gastrointestinal side effects, which dosage form is a controlled release dosage form.

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.

Abstract: The combination of any two of a polyol, a polyol ether, and a low carbon organic alcohol provides a synergistic effect on the solubility of azole compounds, such as metronidazole, in aqueous fluid.

Abstract: Methionine is an effective antioxidant for polypeptides having an amino acid sequence lacking methionine. Compositions containing polypeptides having an amino acid sequence that is free of methionine residues are stabilized from oxidative degradation by combining methionine in the composition in an amount effective to inhibit oxidation of the polypeptide.

Abstract: Azithromycin, administered systemically, is an effective treatment for nodules associated with acne vulgaris.

Abstract: An emulsion for topical application to the skin containing a high molecular weight emulsifier and substantially no emulsifiers of a molecular weight less than 100 kD. The emulsion may be used to prevent or treat dermatoses and may additionally contain pharmaceutically active ingredients.

Abstract: An aqueous solution of metronidazole in which the concentration of metronidazole is higher than 0.75%. The solution contains a combination of solubility-enhancing agents, one of which is a cyclodextrin such as beta-cyclodextrin and the second is niacin or niacinamide. Methods of manufacture and therapeutic use of the solution are disclosed.

Abstract: Increased compliance in the use of topical sunscreens is obtained by combining a topical sunscreen agent in a formulation containing an antibacterial medication such as azelaic acid or an antibiotic.
