Abstract

Oral dosage forms of bisphosphonate compounds, such as zoledronic acid, can be used to treat or alleviate pain or related conditions. The oral bioavailabilty of zoledronic acid can be enhanced by administering the zoledronic acid in the disodium salt form.

First claim

The invention claimed is:

1. A method of treating low back pain comprising orally administering zoledronic acid to a human being in need thereof, wherein the human being receives about 40 mg to about 300 mg of zoledronic acid per month, and wherein the human being experiences pain relief that lasts for a duration of at least 48 hours, and the human being receives zoledronic acid no more often than once daily.

2. The method of claim 1 , wherein the zoledronic acid is administered in an amount and frequency that results in an AUC of zoledronic acid, over a four week period, that is about 100 ng·h/mL to about 2000 ng·h/mL.

3. The method of claim 2 , wherein the zoledronic acid is administered once a month, or less frequently.

4. The method of claim 2 , wherein zoledronic acid is administered for only 1 to 3 months.

5. The method of claim 3 , wherein the mammal experiences pain relief at least 3 weeks after a dose of zoledronic acid is administered.

6. The method of claim 2 , wherein the zoledronic acid is administered weekly.

7. The method of claim 1 , wherein the zoledronic acid is administered 2 to 5 times in a month.

8. The method of claim 1 , wherein the zoledronic acid is administered daily.

9. The method of claim 1 , wherein human being to which the zoledronic acid is administered does not eat food or drink beverage for at least 1 hour before the zoledronic acid is administered.

10. The method of claim 1 , wherein the low back pain is related to vertebral change.

11. The method of claim 1 , wherein the zoledronic acid is administered in an amount and frequency that results in an AUC of zoledronic acid, over a one week period, that is about 20 ng·h/mL to about 500 ng·h/mL.

12. The method of claim 1 , wherein the zoledronic acid is administered in a solid dosage form having a hardness of about 5 kPa to about 20 kPa.

13. The method of claim 1 , wherein the zoledronic acid is administered in a solid dosage form that contains at least about 50% (w/w) of zoledronic acid.

14. The method of claim 1 , wherein the zoledronic acid is administered daily, and a daily dose contains an amount of zoledronic acid that results in an AUC of zoledronic acid that is about 4 ng·h/mL to about 30 ng·h/mL.

15. The method of claim 1 , wherein the human being to which the zoledronic acid is administered does not eat food or drink beverage for at least 30 minutes after the zoledronic acid is administered.
