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.

What is claimed is: 
     
         1 . An extended release pharmaceutical composition, comprising:
 an immediate release portion comprising hydrocodone or a pharmaceutically acceptable salt of hydrocodone, acetaminophen, or a combination thereof; and an extended release portion comprising hydrocodone or a pharmaceutically acceptable salt of hydrocodone, acetaminophen, or a combination thereof;   wherein when the composition is orally administered to a subject in need thereof the composition delivers the hydrocodone or the pharmaceutically acceptable salt thereof and the acetaminophen to the subject's upper gastrointestinal tract for at least about 4 hours to about 12 hours; and   wherein there is substantially no effect on AUC 0-inf  for hydrocodone and acetaminophen when the pharmaceutical composition is administered in a fed versus fasted state.   
     
     
         2 . The extended release pharmaceutical composition of  claim 1 , wherein the extended release component comprises at least one extended release polymer. 
     
     
         3 . The extended release pharmaceutical composition of  claim 2 , wherein the at least one extended release polymer is a polyethylene oxide. 
     
     
         4 . The extended release pharmaceutical composition of  claim 3 , wherein the polyethylene oxide has a molecular weight from about 500,000 Daltons to about 10,000,000 Daltons. 
     
     
         5 . The extended release pharmaceutical composition of  claim 1 , wherein the total amount of the acetaminophen in the composition is from about 250 mg to about 1300 mg; and the total amount of the hydrocodone in the composition is from about 5 mg to about 30 mg. 
     
     
         6 . The extended release pharmaceutical composition of  claim 1 , wherein the total amount of the acetaminophen in the composition is about 325 mg; and the total amount of the hydrocodone in the composition is about 7.5 mg. 
     
     
         7 . The extended release pharmaceutical composition of  claim 1 , wherein the composition is administered to a subject in need thereof at least twice a day. 
     
     
         8 . The extended release pharmaceutical composition of  claim 1 , wherein the composition delivers the hydrocodone or the pharmaceutically acceptable salt thereof and the acetaminophen to the subject's upper gastrointestinal tract for at least about 6 hours. 
     
     
         9 . A method of treating pain in a patient in need thereof, comprising administering to the patient the pharmaceutical composition of  claim 1 . 
     
     
         10 . The method of  claim 9 , wherein the subject in need thereof is suffering from pain or diagnosed with a condition associated with pain, the pain being acute pain or chronic pain. 
     
     
         11 . The method of  claim 10 , wherein the subject in need thereof is suffering from moderate to severe acute pain. 
     
     
         12 . An extended release pharmaceutical composition comprising:
 at least one immediate release portion comprising hydrocodone or a pharmaceutically acceptable salt thereof and acetaminophen and at least one extended release portion comprising an extended release component, hydrocodone or a pharmaceutically acceptable salt thereof, and acetaminophen;   wherein the sum of the amounts of the acetaminophen in the immediate release and the extended release portions is about 325 mg;   wherein the sum of the amounts of the hydrocodone or pharmaceutically acceptable salt thereof in the immediate release and extended release portions is about 7.5 mg; and   wherein the composition can be administered to a subject in need thereof without regard to food.   
     
     
         13 . The extended release composition of  claim 12 , wherein the AUC of hydrocodone when a subject is in a fasted state is bioequivalent to the AUC of hydrocodone when the subject is in a fed state. 
     
     
         14 . The extended release composition of  claim 12 , wherein the AUC of acetaminophen when a subject is in a fasted state is bioequivalent to the AUC of acetaminophen when the subject is in a fed state. 
     
     
         15 . The extended release composition of  claim 12 , wherein the Cmax of hydrocodone when a subject is in a fasted state is bioequivalent to the Cmax of hydrocodone when the subject is in a fed state. 
     
     
         16 . The extended release composition of  claim 12 , wherein there is substantially no effect on AUC 0-inf  for hydrocodone and acetaminophen when the composition is administered in a fed versus fasted state. 
     
     
         17 . A pharmaceutical composition comprising an immediate release portion and an extended release portion, wherein:
 the immediate release portion comprises acetaminophen and hydrocodone or a pharmaceutically acceptable salt thereof,   the extended release comprises acetaminophen, hydrocodone or a pharmaceutically acceptable salt thereof, and an extended release component, and   the total amount of acetaminophen in the pharmaceutical composition is from about 325 mg to about 650 mg and the total amount of hydrocodone or a pharmaceutically acceptable salt thereof in the pharmaceutical composition is from about 7.5 mg to about 15 mg,   wherein the pharmaceutical composition provides an AUC (0-3hr)  for hydrocodone after a single dose from about 1.0 ng·hr/mL/mg to about 5.0 ng·hr/mL/mg.   
     
     
         18 . The pharmaceutical composition of  claim 17 , wherein upon oral administration, the pharmaceutical composition provides an AUC (0-3hr)  for hydrocodone from about 1.50 ng·hr/mL/mg to about 4.25 ng·hr/mL/mg. 
     
     
         19 . The pharmaceutical composition of  claim 17 , wherein upon oral administration, the pharmaceutical composition provides an AUC (0-3hr)  for hydrocodone from about 2.0 ng·hr/mL/mg to about 3.0 ng·hr/mL/mg. 
     
     
         20 . The pharmaceutical composition of  claim 17 , wherein upon oral administration, the pharmaceutical composition provides an AUC 0-12hr  for hydrocodone from about 5 ng·hr/mL/mg to about 25 ng·hr/mL/mg.
