  • Patent number: 5935592
    Abstract: A stable solution, cream, salve, or spray composition containing activated chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for the treatment of vaginitis and endometriosis by reducing any of Candida, Actinobacillus actinomycetemcomitans, Pseudomonades, and Porphyromonas gingivalis present in the vagina or the uterus. The preferred concentration ranges are in the range of about 0.005% to about 2.0% of chlorine dioxide, and in the range of about 0.02% to about 3.0% of phosphate. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.4, at which pH chlorine dioxide becomes activated and releases sufficient chlorine dioxide to reduce motility and become lethal to the involved micro-organisms.

  • Patent number: 5932245
    Abstract: Nanosols and process for preparing the same allow colloidally dispersed solutions of scarcely water-soluble active substances to be stabilized with gelatin or its derivatives, by partly or fully setting the iso-ionic point (IIP, equivalent to a neutral charge) between the gelatin and the surface charged active substance particles. In order to neutralize the charge of the system composed of active substance particles and gelatin, the surface charge of the particles is compensated by a corresponding opposite charge of the gelatin molecules. For that purpose, a determined charge in relation to the isoelectric point (IEP) and the pH value of the solution is set on the gelatin molecules. By stabilizing in this way the practically monodispersed state thus generated, the Ostwald maturation of the colloidal particles of scarcely soluble active substance is strongly reduced.

  • Patent number: 5925376
    Abstract: An improved method of treating psoriasis involves controlling the enhanced proliferation and terminal differentiation of psoriatic epidermis through the activity of epidermal phosphorylase kinase. In general, the method involves contacting psoriatic epidermal cells with a combination of substances affecting the activity of phosphorylase kinase. The combination can be: (1) a calmodulin inhibitor together with a stimulator of cAMP-dependent protein kinase II, (2) a calmodulin inhibitor together with a calcium channel blocker; (3) a stimulator of cAMP-dependent protein kinase II together with a calcium channel blocker; or (4) a calmodulin inhibitor together with a calcium channel blocker and a stimulator of cAMP-dependent protein kinase II. Alternatively, a selective phosphorylase kinase inhibitor such as curcumin can be administered, alone or with an agent such as vitamin D.sub.3 or an analogue thereof, etretinate, diltiazem, or anthralin. The invention also includes pharmaceutical compositions.

  • Patent number: 5919835
    Abstract: Blends of polymers having properties distinct from the individual polymer components and that are suitable for use as carriers of pharmaceutically active agents, are prepared from two or more polyanhydrides, polyesters or mixtures of polyanhydrides and polyesters. The blends have different properties than the polymers used to prepare the blends, providing a means for altering the characteristics of a polymeric matrix without altering the chemical structure of the component polymers. Blends of various polyanhydrides, polyesters, and polyanhydrides and polyesters, containing pharmaceutically active agents, are prepared using solvent mixing or melt mixing procedures.
