Abstract

A solid oral controlled-release dosage form of hydrocodone is disclosed, the dosage form comprising an analgesically effective amount of hydrocodone or a pharmaceutically acceptable salt thereof, and controlled release material.

Claims

1. A solid oral controlled-release dosage form of hydrocodone, the dosage form comprising a matrix comprising hydrocodone or a pharmaceutically acceptable salt thereof and a wax, such that the dosage form provides a ratio of a plasma concentration of hydrocodone at the end of a dosing interval to a maximum plasma concentration of hydrocodone during the dosing interval of from 0.55 to 1 and effective pain relief over a period of time of about 12 hours or longer after administration to a human patient, wherein

the dosage form is a tablet, and

the hydrocodone or pharmaceutically acceptable salt thereof is the only active agent in the dosage form.

2. The dosage form of claim 1, wherein the effective pain relief is provided for about 12 hours.

3. The dosage form of claim 2, wherein said administration is first administration.

4. The dosage form of claim 3, wherein the wax is a fatty acid glyceride.

15. The dosage form of claim 1, wherein the dosage form provides a mean C₂₄/C_max hydrocodone ratio of from 0.55 to 1 after administration to a patient population and the dosing interval is 24 hours.

16. The dosage form of claim 1, wherein the dosage form provides a C₂₄/C_max hydrocodone ratio of from 0.55 to 1 after administration to the human patient and the dosing interval is 24 hours.

22. The dosage form of claim 1, which comprises from about 5 to about 60 mg hydrocodone.

27. The dosage form of claim 1, wherein the dosage form comprises a lubricant.

28. The dosage form of claim 1, wherein the dosage form provides a mean ratio of mean plasma concentrations of hydrocodone at the end of a dosing interval to mean maximum plasma concentrations of hydrocodone during the dosing interval of 0.55 to 1 after administration to a patient population.

29. The dosage form of claim 28, which provides a C₂₄/C_max hydrocodone ratio of from 0.55 to 1 after said administration and the dosing interval is 24 hours.

5. A solid oral controlled-release dosage form of hydrocodone, the dosage form comprising a matrix comprising hydrocodone or a pharmaceutically acceptable salt thereof and a wax, such that the dosage form provides a W₅₀ of hydrocodone of between 4 and 22 hours and a plasma concentration of hydrocodone within a therapeutic range over a period of time of about 12 hours or longer after administration to a human patient, wherein

the dosage form is a tablet, and

the hydrocodone or pharmaceutically acceptable salt thereof is the only active agent in the dosage form.

6. The dosage form of claim 5, wherein the dosage form provides the plasma concentration of hydrocodone within the therapeutic range over a period of time of about 12 hours after administration to the human patient.

7. The dosage form of claim 6, wherein said administration is first administration.

8. The dosage form of claim 5, wherein said administration is first administration.

9. The dosage form of claim 5, wherein the wax is a fatty acid glyceride.

10. The dosage form of claim 5, wherein the dosage form provides a C₂₄/C_max hydrocodone ratio of from 0.55 to 1 after said administration.

11. A solid oral controlled-release dosage form of hydrocodone, the dosage form comprising a matrix comprising hydrocodone or a pharmaceutically acceptable salt thereof and a wax, such that the dosage form provides a T_max of hydrocodone of from about 4 to about 14 hours and a plasma concentration of hydrocodone within a therapeutic range over a period of time of about 12 hours or longer after administration to a human patient, wherein

the dosage form is a tablet, and

the hydrocodone or a pharmaceutically acceptable salt thereof is the only active agent in the dosage form.

12. The dosage form of claim 11, wherein the dosage form provides the plasma concentration of hydrocodone within the therapeutic range over a period of time of about 12 hours after administration to the human patient.

13. The dosage form of claim 12, wherein said administration is first administration.

14. The dosage form of claim 11, wherein said administration is first administration.

17. The dosage form of claim 11, wherein the wax is a fatty acid glyceride.

18. A solid oral controlled-release dosage form of hydrocodone, the dosage form comprising a matrix comprising hydrocodone bitartrate and a wax, such that the dosage form provides a plasma concentration of hydrocodone within a therapeutic range over a period of time of about 12 hours or longer after administration to a human patient, wherein

the dosage form is a tablet, and

the hydrocodone bitartrate is the only active agent in the dosage form.

19. The dosage form of claim 18, wherein the wax is a fatty acid glyceride.

20. The dosage form of claim 18, wherein the amount of the hydrocodone bitartrate in the dosage form is equivalent to from about 5 mg to about 60 mg hydrocodone.

21. The dosage form of claim 18, wherein the dosage form provides a mean C₂₄/C_max hydrocodone ratio of from 0.55 to 1 after administration to a patient population.

23. The dosage form of claim 18, wherein the dosage form provides an in-vitro release of hydrocodone when measured by the USP Basket method at 100 rpm in 700 ml aqueous buffer at a pH of 1.2 at 37°

C. of from 10% to about 45% by weight hydrocodone released at 1 hour.

24. The dosage form of claim 18, wherein the dosage form provides the plasma concentration of hydrocodone within the therapeutic range over a period of time of about 12 hours after administration to the human patient.

25. The dosage form of claim 24, wherein said administration is first administration.

26. The dosage form of claim 18, wherein said administration is first administration.

30. The dosage form of claim 18, wherein the dosage form comprises a lubricant.
