Compositions and methods for treatment of diabetic neuropathies
View Patent ↗The invention provides compositions and methods to treat diabetic neuropathies. In particular, the invention provides combinations of at least two types of antioxidants have complementary effects for use against diabetic neuropathies. The two types of antioxidants include: antioxidants that comprise stabilizing heteroatoms and antioxidants with extended conjugated segments in a ring structure. At least one of each type of provided antioxidant has a pro-oxidative or conditionally pro-oxidative effect.
1. A therapeutic method for treatment of diabetic neuropathy comprising therapeutic administration to a patient in need thereof a pharmaceutically effective amount of a composition comprising at least two types of antioxidant compounds comprising:
a) a pharmaceutically effective amount of at least one of a first type of antioxidant compound selected from the group consisting of taurine, beta-alanine, acetyl-L-carnitine, theanine, and L-citrulline; and
b) a pharmaceutically effective amount of at least one of a second type of antioxidant compound selected from the group consisting of a cobalamin compound and melatonin;
wherein, as measured by the Neuropathic Pain Scale, when administration provides no antioxidants other than those named above, the administration decreases a user's perceived diabetic neuropathic pain by at least 50 percent within 3 to 5 days after the onset of administration.
2. The method of claim 1 , wherein the composition comprises at least four of the first type of antioxidant compound, and the at least four compounds include taurine, beta-alanine, acetyl-L-carnitine and theanine.
3. The method of claim 1 , wherein the composition comprises at least two of the second type of antioxidant compound, and the at least two compounds include melatonin and a cobalamin compound.
4. The method of claim 1 , wherein the cobalamin compound is methylcobalamin.
5. The method of claim 1 , wherein taurine is in the amount from 40 mg to 360 mg.
6. The method of claim 1 , wherein acetyl-L-carnitine is in the amount from 40 mg to 360 mg.
7. The method of claim 1 , wherein melatonin is in the amount from 1 mg to 50 mg.
8. The method of claim 1 wherein the composition comprises:
a) taurine in an amount selected from the range of 40 mg to 360 mg;
b) beta-alanine in an amount selected from the range of 10 mg to 90 mg;
c) acetyl-L-carnitine in an amount selected from the range of 40 mg to 360 mg;
d) theanine in an amount selected from the range of 15 mg to 155 mg;
e) melatonin in an amount selected from the range of 1 mg to 50 mg; and
f) methylcobalamin in an amount selected from the range of 40 μg to 440 μg.
9. The method of claim 1 wherein the composition comprises:
a) taurine in an amount of 200 mg;
b) beta-alanine in an amount of 50 mg;
c) acetyl-L-carnitine in an amount of 200 mg;
d) theanine in an amount of 85 mg;
e) melatonin in an amount of 30 mg; and
f) methylcobalamin in an amount of 240 μg.
10. The method of claim 1 , wherein the cobalamin compound is selected from the group consisting of adenosylcobalamin, methylcobalamin, hydroxycobalamin, or cyanocobalamin.
11. The method of claim 1 , wherein the cobalamin compound is in the amount of from 40 μg to 440 μg in the composition.
12. The method of claim 1 , wherein the composition further comprises an adjuvant.
13. The method of claim 1 , wherein the composition further comprises an excipient.
14. The method of claim 1 , wherein the composition is in a solid dose form.
15. The method of claim 1 , wherein the pain comprises burning or tingling in the feet; aching hands; painful fingers; pain in legs; back pain; retinopathy; or sciatic nerve pain.
