Abstract: A method and preparation for the stimulation of mucosal hydration in a subject in need of such treatment is disclosed. The method comprises administering to the mucosal surfaces of the subject a purinergic receptor agonist such as uridine 5′-diphosphate (UDP), dinucleotide triphosphates; cytidine 5′-diphosphate (CDP), adenosine 5′-diphosphate (ADP), or their therapeutically useful analogs and derivatives, in an amount effective to stimulate mucin secretion. 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.

Abstract: The invention provides a method for increasing hydration and lubrication of lacrimal tissues in a subject in need of such treatment. The method comprises administering to the subject a nicotinic acetylcholine receptor agonist such as nicotine and its analogs, transmetanicotine and its analogs, epibatidine and it analogs, lobeline and its analogs, pyridol derivatives, para-alkylthiophenol derivatives, and imidacloprid and its analogs, in an amount effective to stimulate mucus secretion in the lacrimal system. Pharmaceutical formulations and methods of making the same are also disclosed. Methods of administering the formulation 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, suppository form, or transdermal form.
