The composition is rapidly absorbed through the skin to provide control of harmful habits such as bruxism and tooth clenching. The composition can also be applied to the skin overlying these muscles to control muscle hyperactivity (spasm) and/or trigger points, from other causes. The composition can be formulated to include another active agent such as a non-steroidal anti-inflammatory, for example ketoprofen.

  • 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: 6592889
    Abstract: A gel-type adhesive composite bandage (10) is provided which can be used in the treatment of fungus-involved or discolored toe nails, or for general wound treatment. The bandage (10) includes a base (12) having a preformed recess (16), with a humectant-containing gel (18) within the recess (16). An adhesive-coated web (14) is applied over the base (12) and gel (18). The web (14) is strippable from the base (12) with the gel (18) adhered to the web (14). In the use, the web (14) is removed from the base (12), and the exposed gel (18) is applied directly to the affected toe mail or wound. The remaining portions of the adhesive-coated web (14) is then used to maintain the web (14) and gel (18) in place. The gel (18) preferably includes a polymeric matrix having a substantial quantity of water soluble humectant (for example, glycerin) entrapped within the matrix.

  • Patent number: 6589558
    Abstract: Photoablatable modulator for use in Laser ablation processes on the cornea consisting of a mixture of collagen and vegetable gelatins which is formed in situ on the corneal surface to be treated. A small quantity of a solution at a temperature higher of that of the cornea is applied on the corneal surface and is shaped to form an optically centered lenticule by means of a special device. The solution solidifies at corneal temperatures and forms a rigid gel which adheres strongly on the corneal surface. A dye added in the solution enables the visual monitoring of the ablation process. The lenticular modulator produced with the disclosed method is customized to provide an ablation profile that smoothes the corneal surface and additionally removes the geometrical irregularities that may pre-exist on it. The final shape of the cornea corresponds to the shape of the mold used for the preparation of the modulator.
