Compositions for oral administration of zoledronic acid or related compounds for treating multiple myeloma
Oral dosage forms of bisphosphonate compounds, such as zoledronic acid, can be used to treat or alleviate pain or related conditions. The oral bioavailability of zoledronic acid can be enhanced by administering the zoledronic acid in the disodium salt form.
1. A method of treating multiple myeloma, comprising orally administering zoledronic acid in the disodium salt form to a mammal in need thereof, 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 ngh/mL to about 2000 ngh/mL.
2. The method of claim 1 , wherein the zoledronic acid in the disodium salt form is administered once a month, or less frequently.
3. The method of claim 2 , wherein the zoledronic acid in the disodium salt form is administered for only 1 to 3 months.
4. The method of claim 1 , wherein the zoledronic acid in the disodium salt form is administered weekly.
5. The method of claim 1 , wherein the zoledronic acid in the disodium salt form is administered 2 to 5 times in a month.
6. The method of claim 1 , wherein the zoledronic acid in the disodium salt form is administered daily.
7. The method of claim 1 , wherein the mammal is a human being.
8. The method of claim 7 , wherein the human being to which the zoledronic acid in the disodium salt form is administered does not eat food or drink beverage for at least 1 hour before the zoledronic acid in the disodium salt form is administered.
9. The method of claim 1 , wherein the zoledronic acid in the disodium salt form is administered orally in a dosage form that is substantially free of bioavailability-enhancing agents, and wherein the dosage form is administered in a manner such that zoledronic acid has a bioavailability of 1.5% to 3%.
10. The method of claim 1 , wherein the zoledronic acid in the disodium salt form is administered in an amount that results in an AUC of zoledronic acid that is about 20 ngh/mL to about 2000 ngh/mL each time zoledronic acid in the disodium salt form is administered.
11. The method of claim 10 , wherein the zoledronic acid in the disodium salt form is administered weekly.
12. The method of claim 10 , wherein the mammal is a human being.
13. The method of claim 12 , wherein the human being to which the zoledronic acid in the disodium salt form is administered does not eat food or drink beverage for at least 1 hour before the zoledronic acid in the disodium salt form is administered.
14. The method of claim 10 , wherein the zoledronic acid in the disodium salt form is administered in a solid dosage form having a hardness of about 5 kPa to about 20 kPa.
15. The method of claim 10 , wherein the zoledronic acid in the disodium salt form is administered in a solid dosage form that contains at least about 50% (w/w) of zoledronic acid in the disodium salt form.
16. The method of claim 12 , wherein the human being to which the zoledronic acid in the disodium salt form is administered does not eat food or drink beverage for at least 30 minutes after the zoledronic acid in the disodium salt form is administered.
17. The method of claim 1 , wherein the zoledronic acid in the disodium salt form is administered daily, and a daily dose contains an amount of zoledronic acid in the disodium salt form that results in an AUC of zoledronic acid that is about 4 ngh/mL to about 30 ngh/mL.
18. The method of claim 17 , wherein the mammal is a human being.
19. The method of claim 18 , wherein the human being to which the zoledronic acid in the disodium salt form is administered does not eat food or drink beverage for at least 1 hour before the zoledronic acid in the disodium salt form is administered.
20. The method of claim 17 , wherein the zoledronic acid in the disodium salt form is administered in a manner such that the bioavailability of zoledronic acid is 1.5% to 3% in the mammal being treated.
21. The method of claim 18 , wherein the human being to which the zoledronic acid in the disodium salt form is administered does not eat food or drink beverage for at least 30 minutes after the zoledronic acid in the disodium salt form is administered.
