  • Patent number: 6818629
    Abstract: The present invention provides a method of treating edematous retinal disorders. The method comprises administration of a pharmaceutical formulation comprising a hydrolysis-resistant P2Y receptor agonist to stimulate the removal of pathological extraneous fluid from the subretinal and retinal spaces and thereby reduce the accumulation of said fluid associated with retinal detachment and retinal edema. The P2Y receptor agonist can be administered with therapeutic and adjuvant agents commonly used to treat edematous retinal disorders. The pharmaceutical formulation useful in this invention comprises a P2Y receptor agonist with enhanced resistance to extracellular hydrolysis, such as dinucleoside polyphosphate compounds, or hydrolysis-resistant mononucleoside triphosphates.

  • Patent number: 6740465
    Abstract: Photothermally sensitive recording sheets for color imaging are disclosed comprising a transparent support sheet having a thermal slip layer disposed on one surface of the support and a heat sensitive image layer on the opposite surface of the support. A second opaque (paper) or transparent (plastic) sheet is laminated to the color-producing layer. The image layer comprises photohardenable microcapsules containing a photopolymerizable or photocrosslinkable compound, a photoinitiator and a dye precursor and a developer material external to the microcapsules. Image-wise exposure of the recording sheet to actinic radiation causes selective photohardening of microcapsules sensitive to that radiation. Heating the resultant exposed recording sheet to a temperature well above the developer melting point by for example a thermal head allows the developer to selectively permeate the non-photohardened capsules resulting in the development of an image, including full color images.

  • Patent number: 6730707
    Abstract: The present invention provides a method of reducing intraocular pressure by administering pharmaceutical compositions comprising indole derivatives. The pharmaceutical compositions useful in this invention comprise indole derivatives and melatonin analogs of Formulae I-IV. A preferred embodiment is a method of lowering intraocular pressure using 5-(methoxycarbonylamino)-N-acetyltryptamine (5-MCA-NAT), also known as GR 135531, which has a prolonged duration of action and greater efficacy in lowering intraocular pressure compared to melatonin. The present invention further provides a method of treating disorders associated with ocular hypertension, and a method of treating various forms of glaucoma; the method comprises administering an effective dose of a pharmacuetical composition comprising an indole derivative with or without agents commonly used to treat such disorders.

  • Patent number: 6703376
    Abstract: A method of promoting drainage of mucous secretions in the congested airways of a bedridden/immobilized patient or an intubated/mechanically-ventilated patient is disclosed. The method comprises administering to the airways of the patient a uridine phosphate such as uridine 5′-triphsophate(UTP) or P1,P4-di(uridine-5′) tetraphosphate, an analog of UTP, or any other analog, in an amount effective to promote drainage of fluid in the congested airways, including sinuses, to create the ciliary beat frequency of cilia on the surface lumina epithelia cells, to increase the secretions of mucous by goblet cells and to promote the clearance of retained secretions by hydrating mucous secretions, by stimulating ciliary beat frequency in the airways and by stimulating surfactant production. Pharmaceutical formulations and methods of making the same are also disclosed.
