Composition and method for treating connective tissue damage by transmucosal administration
View Patent ↗The present invention provides a composition, and a method of use thereof for treating connective tissue damage in man and in animals, which comprises a therapeutically effective amount of chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan (hyaluronic acid). Particularly, the present invention provides a composition, and a method of use thereof, for treating connective tissue damage including, but not limited to, arthritic disease, osteoarthritis, rheumatoid arthritis, osterochondrosis dessicans, cartilage damage, joint injury, joint inflammation, joint synovitis, degenerative joint disease (DJD), post surgical DJD, traumatic injury, fracture, tendon damage, ligament damage, skeletal damage, musculoskeletal damage, fiber damage, adipose tissue damage, blood cell damage, and plasma damage. Compositions for delivery of the present invention include those for parenteral, oral, and transmucosal delivery and for direct surgical placement onto the affected tissues.
1. A composition for treating connective tissue damage in a mammal comprising a therapeutically effective amount of: chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan, in the absence of a separate analgesic agent, wherein said composition is in a formulation adapted for transmucosal administration.
2. The composition of claim 1 , wherein said therapeutically effective amount of chondroitin sulfate comprises from between about 0.5 grams to about 1.5 grams of chondroitin sulfate per unit dose of said composition.
3. The composition of claim 2 , wherein said chondroitin sulfate is chondroitin 4-sulfate.
4. The composition of claim 2 , wherein said chondroitin sulfate is chondroitin 6-sulfate.
5. The composition of claim 2 , wherein said chondroitin sulfate is a mixture of chondroitin 4-sulfate and chondroitin 6-sulfate.
6. The composition of claim 1 , wherein said therapeutically effective amount of N-acetyl D-glucosamine is from about 0.5 grams to about 1.5 grams of N-acetyl D-glucosamine per unit dose of said composition.
7. The composition of claim 1 , wherein said therapeutically effective amount of hyaluronan is from about 10 mg to about 50 mg of hyaluronan per unit dose of said composition.
8. The composition of claim 1 , whrein said transmucosal administration is a sublingual administration.
9. The composition of claim 8 , wherein said formulation for sublingual administration comprises gel, paste, film, or any dissolvable polymeric material in which said composition is absorbed via blood vessels under a tongue or a buccal mucosa.
10. The composition of claim 1 , wherein said transmucosal administration is a nasal administration.
11. The composition of claim 10 , wherein said formulation for nasal administration is a nasal spray or mist.
12. The composition of claim 10 , wherein said formulation is flavored.
13. The composition of claim 9 , wherein said formulation is flavored.
14. The composition of claim 9 , wherein said gel comprises hydroxypropyl cellulose and propylene glycol.
15. The composition of claim 9 , wherein said gel comprises hydroxyethyl cellulose, glycerin, and propylene glycol.
16. The composition of claim 9 , wherein said gel comprises hydroxyethyl cellulose.
17. The composition of claim 1 , further comprising one or more therapeutic agents selected from the group consisting of a synthetic or a non-synthetic corticosteroid agent, nonsteroidal anti-inflammatory agent, antirheumatic agent, immunoregulation agent, immunosuppressant agent, articular function augmentor agent, and interleukin production inhibitor.
18. A composition for treating connective tissue damage in a mammal and in a formulation adapted for transmucosal administration, said composition consisting essentially of a therapeutically effective amount of: chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan, in the absence of a separate analgesic agent.
19. A method for treating connective tissue damages in a mammal comprising transmucosally administering to a mammal in need thereof, a therapeutically effective amount of a composition comprising chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan, in the absence of a separate analgesic agent.
20. The method of claim 19 , wherein said transmucosal administration is sublingual or intranasal administration.
21. A method for treating connective tissue damage in a mammal comprising transmucosally administering to a mammal in need thereof, a therapeutically effective amount of a composition consisting essentially of chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan, in the absence of a separate analgesic agent.
22. The method of claim 21 , wherein said transmucosal administration is sublingual or intranasal administration.
