Application Number:	13/926,206
Patent Claims:	1. A therapeutic pharmaceutical composition comprising: a mixture including (a) an opioid; (b) a gel-forming polymer in an amount of about 3 to about 40 wt %; (c) a disintegrant; and (d) a surfactant; wherein the disintegrant is present in an amount sufficient to cause the pharmaceutical composition to exhibit an immediate release profile. 2. The therapeutic pharmaceutical composition of claim 1, wherein the pharmaceutical composition is in unit dose form. 3. The therapeutic pharmaceutical composition of claim 1, wherein the pharmaceutical composition is in suppository, capsule, caplet, pill, gel, soft gelatin capsule, or compressed tablet form. 4. The therapeutic pharmaceutical composition of claim 1, wherein the opioid susceptible to abuse is present in an amount of 0.5 to about 25 wt % of the composition. 5. The therapeutic pharmaceutical composition of claim 1, wherein the disintegrant is present in an amount of about 2 to about 25 wt % of the composition. 6. The therapeutic pharmaceutical composition of claim 1, wherein the surfactant is present in an amount of about 1 to about 10 wt % of the composition. 7. The therapeutic pharmaceutical composition of claim 1, wherein the disintegrant is selected from the group consisting of sodium starch glycolate, crospovidone, and croscarmellose sodium. 8. A therapeutic pharmaceutical composition comprising: a mixture including (a) an opioid selected from the group consisting of alfentanil, buprenorphine, butorphanol, carfentanil, codeine, dezocine, diacetylmorphine, dihydrocodeine, dihydromorphine, diprenorphine, etorphine, fentanyl, hydrocodone, hydromorphone, .beta.-hydroxy-3-methylfentanyl, levo-.alpha.-acetylmethadol, levorphanol, lofentanil, meperidine, methadone, morphine, nalbuphine, oxycodone, oxymorphone, pentazocine, pethidine, propoxyphene, remifentanil, sufentanil, tilidine, tramadol, and pharmaceutically acceptable salts thereof; (b) a gel-forming polymer in an amount of about 3 to about 40 wt %; (c) a disintegrant; and (d) a surfactant; wherein the disintegrant is present in an amount sufficient to cause the pharmaceutical composition to exhibit an immediate release profile. 9. The therapeutic pharmaceutical composition of claim 8, wherein the pharmaceutical composition is in unit dose form. 10. The therapeutic pharmaceutical composition of claim 8, wherein the pharmaceutical composition is in suppository, capsule, caplet, pill, gel, soft gelatin capsule, or compressed tablet form. 11. The therapeutic pharmaceutical composition of claim 8, wherein the opioid is present in an amount of 0.5 to about 25 wt % of the composition. 12. The therapeutic pharmaceutical composition of claim 8, wherein the disintegrant is present in an amount of about 2 to about 25 wt % of the composition. 13. The therapeutic pharmaceutical composition of claim 8, wherein the surfactant is present in an amount of about 1 to about 10 wt % of the composition. 14. The therapeutic pharmaceutical composition of claim 8, wherein the disintegrant is selected from the group consisting of sodium starch glycolate, crospovidone, and croscarmellose sodium. 15. A therapeutic pharmaceutical composition comprising: a mixture including (a) oxycodone hydrochloride; (b) a gel-forming polymer in an amount of about 3 to about 40 wt %; (c) a disintegrant; and (d) a surfactant; wherein the disintegrant is present in an amount sufficient to cause the pharmaceutical composition to exhibit an immediate release profile. 16. The therapeutic pharmaceutical composition of claim 15, wherein the pharmaceutical composition is in unit dose form. 17. The therapeutic pharmaceutical composition of claim 15, wherein the pharmaceutical composition is in suppository, capsule, caplet, pill, gel, soft gelatin capsule, or compressed tablet form. 18. The therapeutic pharmaceutical composition of claim 15, wherein the oxycodone hydrochloride is present in an amount of 0.5 to about 25 wt % of the composition. 19. The therapeutic pharmaceutical composition of claim 15, wherein the disintegrant is present in an amount of about 2 to about 25 wt % of the composition. 20. The therapeutic pharmaceutical composition of claim 15, wherein the surfactant is present in an amount of about 1 to about 10 wt % of the composition. 21. The therapeutic pharmaceutical composition of claim 15, wherein the disintegrant is selected from the group consisting of sodium starch glycolate, crospovidone, and croscarmellose sodium.
