  • Patent number: 6689393
    Abstract: A solution, in particular for hemodialysis or peritoneal dialysis that permits attaining a desired glucose concentration without affecting the concentrations of other components in the solution. The solution consists of at least three individual solutions that are combined and administered after heat sterilization. The first solution contains calcium ions, electrolyte salts and optionally glucose in a concentration of 0-1000 mM and is acidified to a pH of less than 4.0 with a physiologically tolerable acid. The second solution contains glucose in a concentration different from that of the first solution and the remaining components of the first solution in the same concentration. The third solution contains a buffer in the physiological range. Also provided is a method of preparing a solution according to the invention, where the desired mixing ratio of the separate solutions is automatically established by a dialysis machine or peritoneal dialysis cycler.

  • Patent number: 6663892
    Abstract: A solid orally administrable pharmaceutical dosage form for the treatment of gastric disorders includes a first portion containing a therapeutically effective amount of a histamine H2-receptor antagonist, and a second portion immediately adjacent the first portion without an intervening barrier disposed between the first portion and the second portion, the second portion containing a therapeutically effective amount of an antacid. Physical separation of the active ingredients into two different portions without a separating barrier has been found sufficient to prevent degradation of the histamine H2-receptor antagonist due to contact with the antacid. The invention therefore provides stabilization of a histamine H2-receptor antagonist-antacid combination tablet which is comparable to known multiple portion tablets, but without an intervening barrier between the antacid portion and the histamine H2-receptor antagonist portion.

  • Publication number: 20030228374
    Abstract: The present invention comprises a method and composition for treating skin disorders such as seborrheic dermatitis of the scalp, dandruff, and psoriasis. The method includes topically applying to the skin a solution containing a treatment composition comprising one or more types of alkaline buffers such as bicarbonate, carbonate, dibasic phosphate, and tribasic phosphate having a pH in the range of about 7.1 to about 10.8 and a cation such as potassium or sodium serving as a counter ion. The treatment composition is delivered in a pharmaceutically acceptable vehicle at concentrations that vary according to both the severity of the skin disorder, the buffer vehicle, and the ingredients themselves. This biologically benign treatment has been found to efficiently and very quickly treat several types of skin disorders, including but not limited to the redness, dandruff and itching that can occur following skin cleansing with soap.

    Abstract: The present invention provides devices and methods for stabilizing bicarbonate-based solutions for peritoneal dialysis or hemofiltration. The bicarbonate-based solutions of the present invention are formulated and stored in at least two parts—an alkaline bicarbonate concentrate and an acidic concentrate. The alkaline bicarbonate concentrate is adjusted to have a pH of about 8.6 to 10.0. The acidic concentrate is adjusted to have a stable, acidic pH ranging from about 1.0 to 3.0. Upon mixing, although some variation in the pH of the mixed bicarbonate solution exists, the inventors have discovered that with the appropriate selection of the parameters of the concentrates, the pH of the mixed solution is always within an acceptable physiological range.

  • Publication number: 20010051184
    Abstract: The compound curcumin, derived from turmeric, inhibits phosphorylase kinase and, by doing so, exhibits a number of physiological effects related to the control of inflammation and cellular proliferation. However, curcumin is effective only when in solution. Curcumin is almost completely insoluble in water or in oils, but is soluble in alcohols. Accordingly, a method for treating inflammation in a mammal comprising administering curcumin in a solution containing at least one alcohol to a mammal to detectably inhibit the activity of phosphorylase kinase in the blood of the mammal or in a tissue of the mammal. The alcohol is preferably ethanol, 1-propanol, or 2-propanol; most preferably, it is ethanol. Instead of curcumin, a curcumin derivative or curcuminoid can be administered.

  • Patent number: 6328997
    Abstract: An aqueous neutral to mildly alkaline metal bicarbonate solution is disclosed. The solution comprises metal bicarbonate dissolved in the solution, the metal bicarbonate comprising bicarbonate anions and metal cations. In addition there is a pH adjusting agent in the solution in an amount whereby the solution is at a neutral to mildly alkaline pH. Also disclosed is a process of preparing an aqueous neutral to mildly alkaline metal bicarbonate solution comprising bicarbonate anions and metal cations. The process comprises reacting a compound selected from the group consisting of metal carbonate, metal carbonate hydroxide, metal oxide, metal hydroxide and any mixture thereof with an effective concentration of a pH adjusting agent to produce the aqueous neutral to mildly alkaline metal bicarbonate solution, wherein the pH adjusting agent is present in an amount whereby the solution is at a neutral to mildly alkaline pH.

  • Patent number: 6287607
    Abstract: A composition useful as a dietary supplement for providing potassium, calcium, and citrate is presented, as well as processes for producing the composition, and methods for using the composition as a dietary supplement. Administration of the composition counters bone loss associated with aging or menopause by providing bioavailable calcium and, simultaneously, delivering alkali load. In addition, administration of the composition produces a substantial increase in urinary citrate, which counters kidney-stone formation.

  • Patent number: 6254388
    Abstract: A method for whitening teeth which utilizes laser light to activate bleaching agents applied to the teeth. The mouth is first prepared so that the soft tissues of the gums are protected and only the teeth are exposed. The teeth are cleaned to remove any materials which will reduce or nullify the effects of the bleaching agents. A first bleaching composition comprising a peroxide compound is prepared and applied to the teeth. The teeth are exposed to laser light from an argon laser which light activates the peroxide to accelerate the bleaching process without heat. If further whitening is desired, a second bleaching composition comprising a peroxide compound is prepared and applied to the teeth. The teeth are briefly exposed to laser light from a carbon dioxide laser which heat activates the peroxide to accelerate the bleaching process.
