  • Patent number: 6368576
    Abstract: Composition and methods that include potassium nitrate for whitening and/or reducing tooth sensitivity. The dental compositions may optionally include a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions may be applied directly to the person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, dispersed within a solvent, which assists the composition in retaining the dental tray over the person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

  • Patent number: 6350462
    Abstract: An improved porous ceramic body to be embedded in a patient for sustained release of a medicament, and a method of making the ceramic body is provided. To control the release of the medicament, the pores of the ceramic body decrease in diameter from the inner surface to the outer surface of the body whereby the pore diameter is substantially proportional to the distance from the outer surface of the carrier. First, raw ceramic slurry is made from the blend of &bgr;-TCP, deflocculating agent, and water. Next, using a syringe the ceramic slurry is supplied to the internal region of a solvent-absorbable mold from an aperture along the inner wall surface. Then, the ceramic slurry is quickly dehydrated before thinly adhering itself onto the inner wall surface of the mold. Therefore, a preformed body having a hollow is obtained. Next, after fully being dried, the dried preformed body is fired at 1,050° C. for an hour before eventually yielding a spherical carrier for use in sustained release preparation.

  • Patent number: 6334999
    Abstract: To optimize the delivery of all-trans retinoic acid to lung tissue, the potential of vehiculating this drug in liposomes and delivering it via aerosol was determined. Liposomes provide a means to prevent local irritation of lung tissue, reduce pulmonary toxicity, prolong therapeutic levels, and generate high drug concentrations at the tumor sites. Therefore, the delivery of ATRA to the lung tissue in mice was accomplished by nebulization of L-ATRA. The liposomes in the aerosol were uniform, stable, and retained the drug well. The drug was effectively delivered at high concentrations to the lungs of mice and was retained at least up to 96 h after a single exposure to L-ATRA aerosols. The aerosol-delivered ATRA was biologically active as demonstrated by its ability to induce the expression of tissue-type transglutaminase. Aerosol delivery of L-ATRA offers an effective way to deliver high levels of ATRA to the lung without apparent pulmonary toxic effects.
