  • Patent number: 7531525
    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 present invention also provides a method of treating cystic fibrosis. The present invention further provides P1-(2?-deoxycytidine 5?-)P4-(uridine 5?-) tetraphosphate, tetra-(alkali metal) salts such as tetrasodium, tetralithium, tetrapotassium, and mixed (tetra-alkali metal) salts. The present further provides a pharmaceutical formulation comprising a P1-(2?-deoxycytidine 5?-)P4-(uridine 5?-) tetraphosphate, tetra-(alkali metal) salt, in a pharmaceutically acceptable carrier.

  • Publication number: 20080009463
    Abstract: A method and preparation for the stimulation of tear secretion in a subject in need of such treatment is disclosed. The method comprises administering to the ocular surfaces of the subject a purinergic receptor agonist such as uridine 5?-triphosphate (UTP), dinucleotides, cytidine 5?-triphosphate (CTP), adenosine 5?-triphosphate (ATP), or their therapeutically useful analogs and derivatives, in an amount effective to stimulate tear fluid secretion and enhance drainage of the lacrimal system. Pharmaceutical formulations and methods of making the same are also disclosed. Methods of administering the same would include: topical administration via a liquid, gel, cream, or as part of a contact lens or selective release membrane; or systemic administration via nasal drops or spray, inhalation by nebulizer or other device, oral form (liquid or pill), injectable, intra-operative instillation or suppository form.

  • Patent number: 6977246
    Abstract: The present invention relates to certain novel dinucleotides and formulations thereof which are highly selective agonists of the P2Y2 and/or P2Y4 purinergic receptor. They are useful in the treatment of chronic obstructive pulmonary diseases such as chronic bronchitis, PCD, cystic fibrosis, as well as prevention of pneumonia due to immobility. Furthermore, because of their general ability to clear retained mucus secretions and stimulate ciliary beat frequency, the compounds of the present invention are also useful in the treatment of sinusitis, otitis media and nasolacrimal duct obstruction. They are also useful for treatment of dry eye disease and retinal detachment as well as facilitating sputum induction and expectoration.
