  • Patent number: 5700481
    Abstract: A calcitonin, its derivative or a salt thereof is transdermally delivered by iontophoresis in which a substantially constant voltage in the range of 3 to 20 V is applied at an electric current of 0.05 to 0.5 mA/cm.sup.2. In this process, the calcitonin can be delivered transdermally with a higher absorptivity by applying a higher voltage for a short period (at a voltage of about 6 to 14 V for about 5 to 15 minutes) in the initial stage of the voltage application, and then applying a lower voltage for a long period (at a voltage of about 3 to 9 V for about 30 to 40 minutes).

  • Patent number: 5688517
    Abstract: A method for assessing the sensitivity of a patient's tumor cells to cephalomannine and 10-deacetyltaxol in order to treat those tumor cells involves the removal of a sample of the tumor cells and establishing a cell line therefrom. Cells from the cell line are cultured and then contacted with varying concentrations of cephalomannine or 10-deacetyltaxol to form treated cells. The treated cells are assessed to determine the cytotoxic effect of the cephalomannine and/or the 10-deacetyltaxol and, where cytotoxic response is exhibited, a therapeutic dosage is formulated using the selected concentration of cephalomannine or 10-deacetyltaxol and a carrier material. The method is particularly useful for neural and glial tumor cells.

  • Patent number: 5683713
    Abstract: A pharmaceutical and cosmetical preparation which rapidly penetrates through human skin, and which thus is able to bring about the rapid transdermal penetration of a wide variety of active ingredients. The compounds which enhance the rate of dermal penetration are also anti-oxidative agents and thus protect active substances susceptible to oxidative degradation. Preferred agents enhancing penetration and which protect against oxidation are higher esters and higher amides of thioglycolic acid and of mercaptopropionic acid. The preparations can be in the form of mixtures or there may be prepared chemical compounds which are a combination of the active substance and the said thioacids.

  • Patent number: 5683710
    Abstract: A percutaneous absorption preparation for use in the administration of isosorbide dinitrate (ISDN) as a coronary vasodilator into the living body by percutaneous absorption, which has excellent adhesion to the skin and does not cause pain and damage to stratum corneum when peeled off, is disclosed. The pressure-sensitive adhesive layer comprises an acrylic copolymer prepared by copolymerization of a monomer mixture comprising a (meth)acrylic acid alkyl ester and a functional monomer as the essential components, a fatty acid ester having a specified number of carbon atoms, a monoglyceride having a specified number of carbon atoms, and ISDN, and the pressure-sensitive adhesive layer is crosslinked. Since its skin adhesive property is improved by the inclusion of the monoglyceride, release of ISDN is improved and the area of the preparation can be decreased.
