Patent Claims:	1. A method of treating a subject with a disease characterized by the production of mucin, comprising administering to the subject an effective amount of a composition comprising at least one compound selected from the group consisting of analogues and derivatives of 2-amino-nicotinic acid. 2. The method of claim 1, wherein the disease is selected from the group consisting of a chronic obstructive pulmonary disease (COPD), an inflammatory lung disease, and an acute or chronic infectious disease. 3. The method of claim 1, wherein the mucin production occurs in the respiratory tract of the subject. 4. The method of claim 1, wherein the mucin production occurs in the gastrointestinal tract of the subject. 5. The method of claim 4, wherein the mucin production occurs in the pancreas of the subject. 6. The method of claim 2, wherein the disease is asthma. 7. The method of claim 2, wherein the disease is bronchitis. 8. The method of claim 2, wherein the disease is chronic bronchitis. 9. The method of claim 2, wherein the disease is cystic fibrosis. 10. The method of claim 2, wherein the disease is emphysema. 11. The method of claim 2, wherein the disease is gastrointestinal malabsorption syndrome. 12. The method of claim 2, wherein the disease is steatorrhea. 13. The method of claim 2, wherein the disease is diarrhea. 14. The method of claim 2, wherein the disease is allergic inflammation. 15. The method of claim 2, wherein the treatment reduces airway inflammation. 16. The method of claim 2, wherein the treatment reduces inflammatory cells. 17. A method of claim 2, wherein the treatment reduces epithelial-related inflammation. 18. A method of claim 1, wherein the treatment is for bronchial hyperresponsiveness. 19. The method of claim 1, wherein the treatment down-regulates mediators of airway inflammation. 20. The method of claim 19, wherein the mediator is a chemokine. 21. The method of claim 19, wherein the mediator is a cytokine. 22. The method of claim 21, wherein the cytokine is interleukin 9. 23. The method of claim 1, wherein the treatment decreases the number of goblet cells in the respiratory tract. 24. The method of claim 1, wherein the treatment decreases the number of goblet cells in the gastrointestinal tract. 25. The method of claim 1, wherein the treatment decreases the number of submucosal glands in the respiratory tract. 26. The method of claim 1, wherein the treatment decreases the number of submucosal glands in the gastrointestinal tract. 27. The method of claim 1, wherein the 2-amino-nicotinic acid compound is niflumic acid or a pharmaceutically acceptable salt thereof. 28. The method of claim 27, wherein the composition consists essentially of niflumic acid. 29. The method of claim 1, wherein the 2-amino-nicotinic acid compounds are formulated as prodrugs. 30. The method of claim 29, wherein the 2-amino-nicotinic acid compound is niflumic acid. 31. The method of claim 1, wherein the 2-amino-nicotinic acid compounds inhibit chloride channel activity. 32. The method of claim 31, wherein the chloride channel is a calcium activated chloride channel. 33. The method of claim 32, wherein the calcium activated chloride channel is human CLCA1 or CLCA2. 34. The method of claim 1, wherein the composition is administered by a systemic route. 35. The method of claim 34, wherein the composition is administered by a parenteral route. 36. The method of claim 35, wherein the parenteral route is selected from the group consisting of intravenous, intramuscular, intraperitoneal and subcutaneous administration. 37. The method of claim 2, wherein the composition is formulated as a suppository. 38. The method of claim 2, wherein the composition is an extended release formulation for deposit under the skin or intramuscular injection. 39. The method of claim 1, wherein the composition is administered by an oral route. 40. The method of claim 39, wherein the composition is formulated for oral administration in a formulation selected from the group consisting of capsules, tablets, elixirs, suspensions and syrups. 41. The method of claim 39, wherein the composition is formulated as a controlled release formulation. 42. The method of claim 1, wherein the composition further comprises a pharmaceutically acceptable carrier. 43. The method of claim 42, wherein the pharmaceutically acceptable carrier is selected from the group consisting of a surfactant, stabilizing agent, encapsulating agent and absorption-enhancing agent. 44. The method of claim 42, wherein the pharmaceutically acceptable carrier is sterile water or sterile oil. 45. The method of claim 44, wherein the sterile oil is selected from the group consisting of petroleum, animal, vegetable, peanut, soybean, mineral and sesame oil. 46. The method of claim 42, wherein the pharmaceutically acceptable carrier is selected from the group consisting of saline, glycerol and dextrose solutions. 47. The method of claim 1, wherein the composition is administered by inhalation. 48. The method of claim 47, wherein the composition is in the form of an aerosol. 49. The method of claim 1, wherein the composition is administered by an inhaler. 50. The method of claim 49, wherein the inhaler is a metered dose inhaler. 51. The method of claim 49, wherein the inhaler is a dry powder inhaler. 52. The method of claim 1, wherein the composition is administered in a topical formulation as a solution, suspension, gel, ointment or salve. 53. The method of claim 1, wherein the composition is administered in combination with an additional agent for the treatment of diseases selected from the group consisting of asthma, bronchitis, chronic bronchitis, cystic fibrosis, emphysema, gastrointestinal malabsorption syndrome, steatorrhea, diarrhea and allergic inflammation. 54. The method of claim 53, wherein the additional agent is selected from the group consisting of expectorants, mucolytics, antibiotics, antihistamines, steroids, anti-inflammatory agents and decongestants. 55. The method of claim 53, wherein the additional agent is a beta receptor agonist. 56. The method of claim 53, wherein the additional agent is a steroid. 57. The method of claim 53, wherein the additional agent is a leukotriene antagonist. 58. A method of treating a subject with a disease characterized by the production of mucin, comprising administering to the subject an effective amount of a composition comprising niflumic acid or pharmaceutically acceptable salts thereof.
