  • Patent number: 6478946
    Abstract: A method of preparing organic acids (fulvic, humic, and ulmic) for use as an electrolyte for producing high ionizations of precious metals (such as silver) which entails leaching out the organic acid from its source, stabilizing the organic acid first with ascorbic acid followed by sodium benzoate, removing cations, and using the organic acid as an electrolyte. A precious metal (such as silver) is used as a sacrificial electrode in this electrolyte. A non-sacrificial electrode could either be the same precious metal or an inert non-precious metal (titanium or graphite carbons). If the same material is used for the non-sacrificial electrode as for the sacrificial electrode, the size of each electrode may be about the same. If different material is used for the non-sacrificial electrode, its size should be larger that of the sacrificial electrode. Current at about 2 or more volts is applied to the electrodes and the ionization process begins yielding high concentrations of ionized precious metals.

  • Patent number: 6479551
    Abstract: The invention is directed to pharmaceutical compositions useful in the treatment of migraine. The compositions contain metoclopramide and one or more NSAIDs in unit dosage form. By selecting NSAIDs that are non-acidic or segregating the metoclopramide and NSAID, the storage life of the compositions has been increased. Also disclosed are coordinated dosage forms for the sequential release of drugs. The invention encompasses methods of treating migraine using any of these dosage forms.

  • Patent number: 6475529
    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.

  • Patent number: 6468967
    Abstract: The invention provides methods for administering a therapeutically effective amount of daptomycin while minimizing skeletal muscle toxicity. The methods provide daptomycin administration at a dosing interval of 24 hours or greater. This long dosing interval minimizes skeletal muscle toxicity and allows for higher peak concentrations of daptomycin, which is related to daptomycin's efficacy. The invention also provides methods of administering lipopeptide antibiotics other than daptomycin while minimizing skeletal muscle toxicity by administering a therapeutically effective amount of the lipopeptide antibiotic at a dosage interval that does not result in muscle toxicity. The invention also provides methods of administering quinupristin/dalfopristin while minimizing skeletal muscle toxicity by administering a therapeutically effective amount of quinupristin/dalfopristin at a dosage interval that does not result in muscle toxicity.

  • Patent number: 6461591
    Abstract: A pressure-liquefied propellant mixture for aerosols, comprising a fluorinated alkane, in particular 1,1,1,2-tetrafluoroethane and/or 1,1,1,2,3,3,3-heptafluoropropane, and carbon dioxide, makes possible an improvement of the wetting properties of pharmaceutically active compounds, with which the formulation problems existing with hydrofluoroalkanes in relation to suspension as well as solution aerosols can be overcome and thus improved medicinal aerosol formulations can be obtained. With the aid of carbon dioxide, it is also possible to specifically influence the pressure and thus the particle size distribution and also by displacement of oxygen from the hydrofluoroalkanes to improve the storage stability of oxidation-sensitive active compounds.
