A use of a tris (hydroxymethyl) aminomethane pharmaceutically acceptable salt or a composition formed by tris (hydroxymethyl) aminomethane and an inorganic acid or an organic acid in the preparation of drugs for treating or preventing hyperuricemia, gout, acute and chronic arthritis, gouty nephropathy, uric acid nephrolithiasis and related diseases. A use of tris (hydroxymethyl) aminomethane in the preparation of topical pharmaceutical compositions for preventing or treating gout and gouty arthritis by topical and transdermal administration.
- Claim:
1-18. (canceled)
- Claim:
19. A method of prevention or treatment of a disease caused by the combination (crystallization) between uric acid molecules or between the uric acid molecule and a macromolecular substance, comprising administering a therapeutically effective amount of a pharmaceutically acceptable salt of trimethylol aminomethane or a composition comprising the same to a subject in need thereof, wherein the prevention or treatment is achieved by eliminating a harmful effect of the uric acid via forming a uric acid - trimethylol aminomethane complex via bonding between trimethylol aminomethane and a uric acid, [chemical expression included] optionally, the disease is gout or gouty nephropathy, and the macromolecular substance is low density lipoprotein.
- Claim:
20. The method according to claim 19, wherein an acid forming the salt with trimethylol aminomethane comprises an organic acid and an inorganic acid, the inorganic acid or organic acid is selected from a group consisting of a hydrochloric acid, lysine, ascorbic acid, acetic acid, formic acid, phosphoric acid, sulfuric acid, maleic acid or butanedisulfonic acid, so as to form the salt with trimethylol aminomethane or form a compound via hydrogen bonding.
- Claim:
21. The method according to claim 19, wherein the disease is gout, gouty nephropathy, gouty arthritis, uremia, lithangiuria, urate nephropathy, kidney stone or chronic kidney disease (CKD).
- Claim:
22. The method according to claim 19, wherein the therapeutically effective amount of the pharmaceutically acceptable salt of trimethylol aminomethane or the composition comprising the same exhibits the following effects: preventing crystallization of a uric acid, dissolving a crystal of the uric acid and reducing a combination of the uric acid with a macromolecular substance such as blood fat or blood sugar so as to reduce the influence on the blood fat and the blood sugar to eliminate a harmful effect of the uric acid or realize a function for reducing the content of the uric acid.
- Claim:
23. The method according to claim 19, wherein the composition comprises a therapeutically effective amount of the pharmaceutically acceptable salt of trimethylol aminomethane and a food acceptable or pharmaceutically acceptable excipients.
- Claim:
24. The method according to claim 23, wherein the composition is selected from a pharmaceutical composition, a feedstuff composition, a food composition or a health-care composition, optionally the pharmaceutical composition is a human medicament or a poultry medicament.
- Claim:
25. The method according to claim 19, wherein the subject comprises a mammal or a non-mammal, preferably, the mammal is human, preferably, the non-mammal is poultry, more preferably, the poultry is a goose or chicken.
- Claim:
26. The method according to claim 19, wherein the pharmaceutically acceptable salt of trimethylol aminomethane or the composition comprising the same is formulated in the form of injections, oral liquids, tablets, capsules, dialysis liquids, granules, pills, powders, gel ointments or sprays, and is administered to the subject via infusion, orally, smearing, dressing or dialysis.
- Claim:
27. The method according to claim 19, wherein the amount for administration is 0.1 g/kg to 10 g/kg body weight per day, preferably 1.7 g/kg body weight per day, more preferably 3.4 g/kg body weight per day.
- Claim:
28. The method according to claim 19, wherein when the composition is in the form of solutions, the composition is formulated as an aqueous solution with a pH value of 5.0 to 11.0, preferably an aqueous solution with a pH value of 7.4 ± 0.5.
- Claim:
29. A method of prevention or treatment of gout or gouty arthritis, comprising administering a therapeutically effective amount of trimethylol aminomethane or a pharmaceutically acceptable salt thereof, wherein the treatment or prevention are via topical transdermal administration with the form of topical external transdermal medicament.
- Claim:
30. The method according to claim 29, wherein the topical external transdermal medicament is in the form of creams, ointments, gels, transdermal preparations, foams, sprays, lotions, solutions, emulsions or suspensions, preferably gels.
- Claim:
31. The method according to claim 19, wherein the disease is hyperuricemia, gout or a disease caused by a high content of a uric acid.
- Claim:
32-33. (canceled)
- Claim:
34. The method according to claim 31, wherein the prevention or treatment of hyperuricemia, gout or gouty arthritis in poultry, comprises administering a therapeutically effective amount of trimethylol aminomethane or a composition comprising the same to a poultry subject in need thereof, wherein the prevention or treatment is achieved by forming a uric acid - trimethylol aminomethane complex via bonding between trimethylol aminomethane and a uric acid, [chemical expression included] .
