1. A pharmaceutical composition for extended release of oxycodone and acetaminophen, comprising:
- at least one extended release portion comprising oxycodone or a pharmaceutically acceptable salt of oxycodone, 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 oxycodone or salt in the composition is about 7.5 mg to about 15 mg;
wherein upon oral administration of the composition to a subject in a fasted state, the composition provides an AUC0-1.7h for acetaminophen of about 5 ng·
h/ml/mg to about 13 ng·
h/ml/mg;
an AUC1.7-48h for acetaminophen of about 25 ng·
h/ml/mg to about 75 ng·
h/ml/mg;
an AUC0-2.8h for oxycodone or salt of about 1 ng·
h/ml/mg to about 3 ng·
h/ml/mg; and
AUC2.8-48h for oxycodone or salt of about 7.5 ng·
h/ml/mg to about 15 ng·

Abstract
The present disclosure provides extended release pharmaceutical compositions comprising oxycodone and acetaminophen that produce a quick initial onset of analgesia, yet, maintain analgesia for about 12 hours after administration of the composition to a subject in need thereof. The pharmaceutical compositions disclosed herein also reduce the levels of acetaminophen in a subject'"'"'s blood near the end of the dosing interval because the acetaminophen released by the pharmaceutical composition is being eliminated by a subjects body faster than it is being absorbed.

31. An extended release pharmaceutical composition, comprising:
-
at least one extended release portion comprising oxycodone or a pharmaceutically acceptable salt of oxycodone, 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 oxycodone 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 oxycodone 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°
