  • Publication number: 20040044080
    Abstract: Methods and formulations for treating dyspareunia are provided. A pharmaceutical composition formulated so as to contain a therapeutically effective amount of nitroglycerin is administered to the vagina or vulvar area of the individual undergoing treatment. Preferred formulations are immediate release formulations in which at least 80% of the nitroglycerin in the formulation is released therefrom within 4 hours following administration. The formulations may contain one or more additional active agents, e.g., agents that are also useful to treat dyspareunia and/or potentiate the action of nitroglycerin. Such additional agents include vasoactive agents such as prostaglandins, phosphodiesterase inhibitors, androgens such as testosterone, estrogens such as estradiol, and selective modulators of estrogen and androgen receptors. A kit for a patient to use in the self-administration of the formulation is also provided.

  • Patent number: 4648529
    Abstract: An apparatus and process for storing beads in a liquid medium and for draining and dispensing said beads essentially in the absence of said liquid medium is described. In one embodiment, the apparatus is designed so that the liquid medium in which the beads are stored can be captured in a separate compartment from the bead-containing compartment and the beads can be delivered without the liquid medium when the apparatus in inverted. This apparatus is designed so that the liquid medium will join with the beads for storage in the bead-containing compartment when the apparatus is upright. In another embodiment, the apparatus includes a bottle with a removable, threaded inner container which is used to drain the liquid medium from the beads prior to attachment to a separate bead dispenser.

  • Patent number: 4409335
    Abstract: An ion exchange method for the separation of hemoglobin A.sub.1 from its Schiff base precursors and from nonglycosylated hemoglobin in a sample of human blood. The known method of lysing the sample, using it to impregnate a weak cation exchange resin, eluting out the glycosylated components with a buffer solution containing from about 0.6 M to about 0.11 M alkali metal ion dissolved therein, and recovering the eluate, is modified by the inclusion of a dihydroxyboryl compound in either the hemolysate, the elution buffer, or both.

  • Patent number: 4389491
    Abstract: An ion exchange method and kit for the separation of hemoglobin A.sub.1c from other hemoglobin components in a sample of human blood. The sample is lysed, then used to impregnate a weak cation exchanger. Two buffer solutions are then passed through the column in succession, the first having an alkali metal ion concentration of from about 0.02M to about 0.05M and the second having an alkali metal ion concentration of from about 0.06M to about 0.11M. The second eluate contains substantially all of the hemoglobin A.sub.1c and substantially none of the other hemoglobin components in the original sample. Analysis of the second eluate thus provides a reliable indication of the long-term glucose level in the blood of a patient, and hence the patient's ability to regulate the quantity of glucose ingested. The hemolysate with the Schiff base precursor is introduced directly to the chromatographic column.
