  • Patent number: 7815960
    Abstract: Green tea formulations and methods for the preparation thereof are shown and described. Generally speaking, the method of preparation includes the mixing of fresh tea leaves in an amount of cold water, followed by pulverization of the leaves to release their intracellular material from the cells of the green tea leaves into the water and form an aqueous extract component. The remaining cellular material forms a leaf residue component which is removed from the mixture. Once the leaf residue is removed, the aqueous extract component is collected and may be dried or further processed to produce a final tea extract that has good natural color, robust natural flavor, and pleasant organoleptic properties, which also is high in polyphenol content, and may be used for various purposes such as the creation of a green tea beverage.

  • Publication number: 20070141204
    Abstract: A beverage and supplement system includes a beverage container having: i) a liquid contained therein; and ii) a dispensive opening. A removable envelope is in communication with the dispensive opening of the container, and has a first side sealed to a second side with the supplement being contained therebetween. The second side of the envelope is rupturable upon application of force to the first side in an amount sufficient to rupture the second side without rupturing the first side, in order to dispense the supplement from the envelope without contacting the supplement with an external object.

  • Publication number: 20050058695
    Abstract: Sustained delivery formulations of norethindrone are disclosed and described. In one aspect, the formulation may be a transdermal formulation that includes both norethindrone and norethindrone acetate. In another aspect, the formulation may further include a penetration enhancer. Coadministration of norethindrone and norethindrone acetate has been found to provide a number of advantages, such as achievement of peak norethindrone serum levels substantially within 24 hours after initiation of administration.

  • Patent number: 6730318
    Abstract: The adhesive capability of matrix-type transdermal devices for the delivery of drugs, cosmetics, emollients and the like is altered by incorporating into the pressure-sensitive adhesive an effective amount of a polydiorganosiloxane polymer fluid adhesion adjusting agent. The properties of the pressure-sensitive adhesive are modified to enable a matrix-type patch to adhere temporarily to the skin for a period sufficient to accomplish its desired delivery purpose and then be removed without causing skin damage or irritation and without leaving substantial adhesive residue on the skin. Polydimethylsiloxanes (dimethicones) are preferred adhesion adjusting agents and acrylic-based polymers are preferred pressure-sensitive adhesives. Matrix-type patches containing anti-wrinkle agents formulated with dimethicones in the adhesive for application to areas on the face and particularly around the eyes are especially useful.

  • Patent number: 6727401
    Abstract: A device for treating antifungal infections of toenails and fingernails is made up of an occlusive backing layer and a pressure sensitive adhesive matrix layer in which is uniformly dispersed an effective amount of an antifungal agent and, optionally, a chemical enhancer. The matrix layer has a first surface adhering to the backing layer and a second surface adapted to be in diffusional contact with the infected nail and surrounding skin area. The device is configured, when applied, to cover and adhere to the nail and surrounding skin areas for an extended period of time without causing irritation to the skin or inhibiting normal physical activity while providing a continuous delivery of antifungal agent to the infected area.

  • Publication number: 20020037311
    Abstract: The present invention to provide methods, pharmaceutical formulations, and devices for the transdermal delivery of 5-substituted-6-cyclic-5,6,7,8,-tetrahydronaphthalene2-ol compounds (“lasofoxifene” or “CP-336,156”) and pharmaceutically acceptable salts thereof. The invention also provides transdermal compositions of CP-336,156 or its salts dissolved or dispersed in a suitable carrier vehicle, optionally containing permeation enhancers and other excipients. The carrier vehicle may be a pressure sensitive adhesive, polymeric reservoir, or a fluid of controlled viscosity. The carrier vehicle may be contained in a device for purposes of holding the composition against the skin surface. Such devices may be in the form of matrix patches (drug in adhesive) or reservoir patches (drug in a liquid or polymeric reservoir with peripheral, in-line, or over-layed pressure sensitive adhesive).

  • Patent number: 6299925
    Abstract: A solid state water soluble formulation in granular or tablet form is provided. The formulation is a natural products formulation containing a green tea plant extract in combination with other ingredients which create an effervescent liquid composition upon dispensing the formulation in a liquid. The liquid form of administration, as well as the effervescent properties of the dissolved formulation increase bioavailability of the advantageous components of the green tea plants such as Polyphenols, by increasing absorption speed and amount in the human body. The formulation may include additional components such as, other plant extracts, vitamins, ionic minerals, and other substances purported to be of a health benefit.

  • Patent number: 6180133
    Abstract: An anti-wrinkle skin treating composition comprises a pressure sensitive matrix patch having dissolved in the adhesive a mixture of antioxidants in the form of a Vitamins C ester and Vitamin E. Also preferably dissolved in the adhesive are glycerine and a polydiorganosiloxane adhesion-adjusting agent. Optionally dissolved in the adhesive is also one or more members selected from the group consisting of moisturizing agents, skin collagen synthesis promoting agents and exfoliating agents. When applied to a wrinkled skin area the composition acts to diminish fine wrinkles and improves the overall thickness, elasticity, firmness and smoothness of the skin. The modified adhesive properties of the patch are sufficient to maintain the patch in place on the skin for the recommended treatment period while allowing the patch to be readily removed without causing skin irritation or leaving adhesive residue on the skin.
