Title:Tamper resistant composition comprising hydrocodone and acetaminophen for rapid onset and extended duration of analgesia
Abstract: The present disclosure provides an extended release pharmaceutical composition comprising hydrocodone and acetaminophen that provides a rapid onset of analgesia, and reduced levels of acetaminophen near the end of the dosing interval. Also provided are methods for reducing the risk of acetaminophen-induced hepatic damage in a subject being treated with an acetaminophen containing composition, as well as methods for treating pain in a subject in need thereof.

5. The pharmaceutical composition of claim 1, wherein the AUC.sub.2.4-36h for hydrocodone or salt is about 13 ngh/mL/mg to about 17 ngh/mL/mg.

6. The pharmaceutical composition of claim 1, wherein the composition comprises about 650 mg of acetaminophen and about 15 mg of hydrocodone or salt.

7. The pharmaceutical composition of claim 1, wherein the composition comprises about 325 mg of acetaminophen and about 7.5 mg of hydrocodone or salt.

8. The pharmaceutical composition of claim 7, wherein the composition is in the form of a tablet and a single dose comprises two tablets.

9. The pharmaceutical composition of claim 1, wherein the extended release component comprises at least one extended release polymer.

10. The pharmaceutical composition of claim 9, wherein the at least one extended release polymer is a polyethylene oxide.

11. The pharmaceutical composition of claim 10, wherein the molecular weight of the polyethylene oxide is from about 500,000 Daltons to about 10,000,000 Daltons.

12. The pharmaceutical composition of claim 1, wherein the composition further comprises at least one immediate release portion comprising hydrocodone or a pharmaceutically acceptable salt thereof, acetaminophen, or a combination thereof.

13. The pharmaceutical composition of claim 12, wherein the at least one immediate release portion comprises from about 20% to about 30% of the total amount of hydrocodone or salt in the composition and from about 40% to about 60% of the total amount of acetaminophen in the composition; and the at least one extended release portion comprises the balance of each of the hydrocodone or salt and the acetaminophen.

14. The pharmaceutical composition of claim 12, wherein the composition comprises (a) one immediate release portion comprising the hydrocodone or salt and the acetaminophen, and (b) one extended release portion comprising the extended release polymer, the hydrocodone or salt and the acetaminophen.

15. The pharmaceutical composition of claim 14, wherein the immediate release portion comprises, by weight of the immediate release portion, from about 70% to about 80% acetaminophen and from about 0.5% to about 1% of hydrocodone or salt; and the extended release portion comprises, by weight of the extended release portion, from about 30% to about 50% of the extended release polymer, from about 20% to about 40% of acetaminophen, and from about 0.5% to about 2% of hydrocodone or salt.

16. A therapeutically effective pharmaceutical composition for oral administration in the treatment of pain, comprising: at least one extended release portion comprising hydrocodone or a pharmaceutically acceptable salt thereof, acetaminophen, and an extended release component; wherein the total amount of acetaminophen in the composition is about 325 mg to about 650 mg, and the total amount of hydrocodone or salt in the composition is about 7.5 mg to about 15 mg; wherein when the composition is orally administered to a subject in need thereof, the subject attains therapeutic blood levels of both the hydrocodone and the acetaminophen within about one hour after administration of the composition and maintains analgesia for about 12 hours after administration of the composition; and wherein upon placement of the composition in an in vitro dissolution test comprising USP Paddle Method at a paddle speed of about 100 rpm in 900 ml of 0.1N HCl using a USP type II apparatus at a constant temperature of 37.degree.
