Methods and Compositions to Inhibit Dependence on Opioids

Abstract

The present invention provides a method of inhibiting dependence to an opioid by a human subject in need thereof. The method comprises administering an effective amount of a pharmaceutical composition to the subject during opioid therapy. The pharmaceutical composition comprises a) a non-steroidal anti-inflammatory drug (NSAID); and b) a co-agent selected from the group consisting of: fexofenadine, ketotifen, desloratadine, cetirizine, salts thereof and combinations thereof.

1 . A method of inhibiting dependence to an opioid by a human subject in need thereof, comprising:
 administering an effective amount of a pharmaceutical composition to the subject during opioid therapy, wherein the pharmaceutical composition comprises:   a) a non-steroidal anti-inflammatory drug (NSAID); and   b) a co-agent selected from the group consisting of: fexofenadine, ketotifen, desloratadine, cetirizine, salts thereof and combinations thereof;   wherein dependence to an opioid is inhibited in the human subject.   
     
     
         2 . The method of  claim 1  wherein the NSAID is selected from the group consisting of:
 aspirin, ibuprofen, naproxen, diclofenac, diflunisal, etodolac, indomethacin, ketoprofen, ketorolac, meloxicam, nabumetone, oxaprozin, piroxicam, salsalate, sulindac, and tolmetin. 
 
     
     
         3 . The method of  claim 1  wherein the NSAID is ibuprofen and the co-agent is fexofenadine. 
     
     
         4 . The method of  claim 1  wherein the amount of ibuprofen is about 150 mg to about 900 mg, and the amount of fexofenadine is about 60 mg to about 180 mg. 
     
     
         5 . The method of  claim 1  wherein the ibuprofen and the fexofenadine is combined in one unit dose. 
     
     
         6 . The method of  claim 1  wherein the ibuprofen and the fexofenadine is in the form of a tablet, lozenge or chewing gum. 
     
     
         7 . The method of  claim 1  wherein the NSAID is ibuprofen and the co-agent is ketotifen. 
     
     
         8 . The method of  claim 1  wherein the amount of ibuprofen is about 1200 mg to about 1600 mg, and the amount of ketotifen is about 0.5 mg to about 3 mg. 
     
     
         9 . The method of  claim 1  wherein the daily dose of ibuprofen is about 2400 mg to about 3200 mg, and the daily dose of ketotifen is about 2 mg. 
     
     
         10 . The method of  claim 9  wherein the ibuprofen and the ketotifen is combined in one unit dose. 
     
     
         11 . The method of  claim 10  wherein the ibuprofen and the ketotifen is in the form of a tablet, lozenge or chewing gum. 
     
     
         12 . A method of inhibiting dependence to an opioid by a human subject in need thereof, comprising:
 administering to the subject an effective amount of a pharmaceutical composition during an opioid withdrawal period, wherein the pharmaceutical composition consists essentially of:   a) about 1200 mg to about 1600 mg of ibuprofen, and   b) about 0.5 mg to about 3 mg ketotifen,   wherein dependence to an opioid is inhibited in the human subject.   
     
     
         13 . The method of  claim 12  wherein the daily dose of ibuprofen is about 2400 mg to about 3200 mg, and the daily dose of ketotifen is about 2 mg. 
     
     
         14 . The method of  claim 12  wherein the ibuprofen and the ketotifen are combined in one unit dose. 
     
     
         15 . The method of  claim 12  wherein the ibuprofen and the ketotifen are in the form of a tablet, lozenge or chewing gum. 
     
     
         16 . A pharmaceutical composition comprising a) an NSAID, and/or a salt thereof; and b) a co-agent selected from the group consisting of: fexofenadine, ketotifen, desloratadine, cetirizine salts thereof and combinations thereof. 
     
     
         17 . The pharmaceutical composition of  claim 16  wherein the NSAID is selected from the group consisting of: aspirin, ibuprofen, naproxen, diclofenac, diflunisal, etodolac, indomethacin, ketoprofen, ketorolac, meloxicam, nabumetone, oxaprozin, piroxicam, salsalate, sulindac, and tolmetin. 
     
     
         18 . The pharmaceutical composition of  claim 17  wherein the amount of ibuprofen is about 2400 mg to about 3200 mg, and the amount of ketotifen is about 2 mg. 
     
     
         19 . The pharmaceutical composition of  claim 18  wherein the ibuprofen and the ketotifen is combined in one unit dose. 
     
     
         20 . The pharmaceutical composition of  claim 19  wherein the ibuprofen and the ketotifen is in the form of a tablet, lozenge or chewing gum.
