Compositions of the invention can comprise therapeutic amounts of: chondroitin sulfate and hyaluronan, and optionally include N-acetyl D-glucosamine.
1. A method of treating a symptom associated with a kidney stone or a ureteral stone in a subject in need, comprising administering to the subject in need an effective amount of a composition comprising an effective amount of chondroitin sulfate and hyaluronan.
2. The method of claim 1 , wherein said chondroitin sulfate is CS4, chondroitin sulfate, CS6 chondroitin sulfate, or a mixture of CS4 and CS6 chondroitin sulfate.
3. The method of claim 1 , wherein said effective amount of chondroitin sulfate is between about 0.1 grams to about 10 grams per unit dose of the composition.
4. The method of claim 1 , wherein said effective amount of hyaluronan is about 10 mg to about 1000 mg of hyaluronan per unit dose of the composition.
5. The method of claim 1 , wherein said composition further comprises an effective amount of N-acetyl D-glucosamine.
6. The method of claim 5 , wherein said effective amount of N-acetyl D-glucosamine is between about 0.5 grams to about 10 grams per unit dose of the composition.
7. The method of claim 1 , wherein said composition further comprises an excipient to facilitate the treatment.
8. The method of claim 1 , wherein said composition is a sterile solution or a sterile suspension.
9. The method of claim 1 , wherein said composition is directly instilled into the kidney, bladder, or ureter, or urethra of the urinary tract of the subject in need.
10. The method of claim 9 , wherein said composition is instilled before, during, or after a separate treatment for the kidney or ureteral stones.
11. The method of claim 10 , wherein said treatment for the kidney or ureteral stones is lithotripsy or other surgical procedures.
12. The method of claim 1 , wherein said composition is administered to the urinary tract of the subject in need through a catheter to coat the urinary tract of the subject in need.
13. The method of claim 1 , wherein said symptom is urinary tract pain, inflammation, or infection.
14. The method of claim 1 , wherein said composition facilitates kidney or ureteral stones or fragments thereof passing through the kidney, bladder, ureter, or urethra of the urinary tract of said subject.
15. A method to alleviate or reduce pain, inflammation, or infection associated with a kidney stone or a ureteral stone in man or in animals, comprising administering to a subject in need an effective amount of a composition comprising an effective amount of chondroitin sulfate and hyaluronan, before, during, or after a separate treatment of the kidney or ureteral stones.
16. The method of claim 15 , wherein said treatment of kidney or ureteral stones is by lithotripsy or other surgical procedures.
17. The method of claim 15 , wherein said composition further comprises an effective amount of N-acetyl D-glucosamine.
18. The method of claim 17 , wherein said composition further comprises one or more excipients to facilitate the treatment.
19. The method of claim 15 , wherein said composition further facilitates kidney or ureteral stones passing through the kidney, bladder, ureter, or urinary tract of said subject.
20. The method of claim 15 , wherein said composition is directly instilled into the kidney, bladder, ureter, or urethra administered through a catheter.
