  • Publication number: 20070207107
    Abstract: A water-in-oil emulsion is provided in which the lipophilic phase of the emulsion contains a silicone fluid and an emulsifier, a hydrophilic phase, and a pharmaceutically active compound. The active pharmaceutical ingredient is dissolved or dispersed in the emulsion and is partitioned in the emulsion so that all or a portion of the amount of the chemical compound dissolved or dispersed in the emulsion is dissolved or dispersed in the aqueous phase of the emulsion. The emulsion of the invention provides increased penetration into skin of the chemical compound dissolved or dispersed in the aqueous phase.

  • Patent number: 6620435
    Abstract: The present invention generally relates to pharmaceutical compositions that enable control of drug, delivery properties and the development of optimal drug delivery strategies customized for particular drugs and particular diseases. The composition includes a dissolved pharmaceutical that has the capacity to permeate the stratum corneum layer of the epidermis and become available systemically, and a pharmaceutical in a microparticulate state that does not readily cross the stratum corneum of the epidermis. The dissolved and microparticulate pharmaceuticals may be the same or different pharmaceuticals. Methods for the preparation and use of the compositions are also provided. In a preferred embodiment, the invention finds particular use in a formulation for the topical application of dapsone for the treatment of acne. In another preferred embodiment, the invention finds particular use for the treatment of herpes lesions.

  • Patent number: 6432415
    Abstract: Bioadhesive formulations to deliver, for both local and systemic effects, a wide variety of drugs of varying degrees of solubility are described. These formulations can be gels or aerosols and comprise a water-insoluble, pharmaceutically acceptable alkyl cellulose, a solvent system comprising a volatile solvent and water, a solubilizing agent or a dispersing agent, or a mixture thereof, and a pharmaceutical. These formulations can be made bioerodible and release the pharmaceutical in a controlled manner. Formulations further comprising a propellant such as 1,1-difluoroethane are also provided. The delivery can be made to a skin surface or to a mucosal surface. Methods for preparing and administering these formulations are also provided. Several specific examples using the anti-ulcer medication 2-amino-7-(1-methylethyl)-5-oxo-5H-[1]benzopyrano-[2,3-b]-pyridine-3-carboxylic acid are provided.
