Pyridoxamine for the treatment of diabetic intermediaries and post-amadori inhibition
The present invention provides pharmaceutical compositions comprising dosage units of pyridoxamine, or a pharmaceutically acceptable salt thereof; and a pharmaceutically acceptable carrier, and methods for their use in limiting the progression of renal disease and/or diabetic complications in human diabetic patient.
1. A method for treating diabetic nephropathy in a human diabetic patient comprising orally administering to a human diabetic patient with a baseline serum creatinine concentration of greater than or equal to 1.3 mg/dL between 100 mg and 600 mg per day of pyridoxamine, or a pharmaceutically acceptable salt thereof, wherein the human diabetic patient has diabetic nephropathy, macroalbuminuria, and type II diabetes, and wherein the human diabetic patient is being treated with angiotensin converting enzyme inhibitor therapy or angiotensin receptor blocker therapy.
2. The method of claim 1 , wherein the human diabetic patient has failed to respond adequately to angiotensin converting enzyme inhibitor therapy or angiotensin receptor blocker therapy.
3. The method of claim 1 , wherein the pyridoxamine, or a pharmaceutically acceptable salt thereof, is administered once or twice a day.
4. The method of claim 2 , wherein the pyridoxamine, or a pharmaceutically acceptable salt thereof, is administered once or twice a day.
5. The method of claim 1 , wherein the pyridoxamine, or a pharmaceutically acceptable salt thereof, is administered as an oral dosage form selected from the group consisting of a 50 mg oral dosage form, a 75 mg oral dosage form, a 100 mg oral dosage form, a 125 mg oral dosage form, a 150 mg oral dosage form, a 175 mg oral dosage form, a 200 mg oral dosage form, a 250 mg oral dosage form, and a 300 mg oral dosage form.
6. The method of claim 5 , wherein the oral dosage form is administered once or twice a day.
7. The method of claim 5 , wherein the oral dosage form is selected from the group consisting of a 50 mg oral dosage form, a 250 mg oral dosage form, and a 300 mg oral dosage form.
8. The method of claim 7 , wherein the oral dosage form is administered once or twice a day.
9. The method of claim 2 , wherein the pyridoxamine, or a pharmaceutically acceptable salt thereof, is administered as an oral dosage form selected from the group consisting of a 50 mg oral dosage form, a 75 mg oral dosage form, a 100 mg oral dosage form, a 125 mg oral dosage form, a 150 mg oral dosage form, a 175 mg oral dosage form, a 200 mg oral dosage form, a 250 mg oral dosage form, and a 300 mg oral dosage form.
10. The method of claim 9 , wherein the oral dosage form is administered once or twice a day.
11. The method of claim 9 , wherein the oral dosage form is selected from the group consisting of a 50 mg oral dosage form, a 250 mg oral dosage form, and a 300 mg oral dosage form.
12. The method of claim 11 , wherein the oral dosage form is administered once or twice a day.
13. The method of claim 1 , wherein between 100 mg and 600 mg per day of pyridoxamine, or a pharmaceutically acceptable salt thereof is administered to the human diabetic patient.
14. The method of claim 13 , wherein the pyridoxamine, or a pharmaceutically acceptable salt thereof, is administered once or twice a day.
15. The method of claim 13 , wherein the pyridoxamine, or a pharmaceutically acceptable salt thereof, is administered as an oral dosage form selected from the group consisting of a 50 mg oral dosage form, a 250 mg oral dosage form, and a 300 mg oral dosage form.
16. The method of claim 15 , wherein the oral dosage form is administered once or twice a day.
