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 a bitartrate salt of hydrocodone and microcrystalline cellulose, the dosage form, after administration to a human subject, providing a C₂₄/C_max hydrocodone ratio of from about 0.55 to about 1.0, wherein

the dosage form is a tablet,

the amount of hydrocodone in the dosage form is from about 0.5 mg to about 1250 mg, and

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

2. The dosage form of claim 1, which provides a therapeutic effect for about 24 hours.

3. The dosage form of claim 1, wherein said administration is first administration.

4. The dosage form of claim 1, wherein the matrix comprises a cellulose ether.

5. The dosage form of claim 4, wherein the cellulose ether is an alkylcellulose.

6. The dosage form of claim 4, wherein the cellulose ether is a hydroxyalkylcellulose.

7. The dosage form of claim 6, wherein the hydroxyalkylcellulose is hydroxypropylcellulose.

8. The dosage form of claim 1 which provides a C₂₄/C_max hydrocodone ratio of 0.55 to 0.85.

9. The dosage form of claim 8, which provides a C₂₄/C_max hydrocodone ratio of 0.6 to about 0.7.

10. The dosage form of claim 1, which provides a T_max of hydrocodone at about 8 to about 14 hours after administration of the dosage form.

11. The dosage form of claim 1, which comprises an amount of the hydrocodone bitartrate salt which is equivalent to from about 5 mg to about 60 mg of hydrocodone.

12. A solid oral controlled-release dosage form of hydrocodone, the dosage form comprising a matrix comprising a bitartrate salt of hydrocodone and microcrystalline cellulose, the dosage form, after administration to human subjects, providing a mean C₂₄/C_max hydrocodone ratio of from about 0.55 to about 1.0, wherein

the dosage form is a tablet,

the amount of hydrocodone in the dosage form is from about 0.5 mg to about 1250 mg, and

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

the dosage form is a tablet,

the amount of hydrocodone in the dosage form is from about 0.5 mg to about 1250 mg, and

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

22. The dosage form of claim 21, wherein said administration is first administration.

23. The dosage form of claim 21, wherein the dosage form provides a C₂₄/C_max hydrocodone ratio of from about 0.55 to about 1 after said administration.

24. The dosage form of claim 23, which provides C₂₄/C_max hydrocodone ratio of from 0.55 to about 0.85.

28. A solid oral controlled-release dosage form of hydrocodone, the dosage form comprising a matrix comprising hydrocodone or a pharmaceutically acceptable salt thereof and microcrystalline cellulose, wherein

the dosage form, after administration to human subjects, provides a mean W₅₀ of hydrocodone of between 4 and 22 hours and a therapeutic effect for about 24 hours, wherein

the dosage form is a tablet,

the amount of hydrocodone in the dosage form is from about 0.5 mg to about 1250 mg, and
