The therapeutic pharmaceutical composition of claim 8, wherein the pharmaceutical composition is in a suppository, capsule, caplet, pill, gel, soft gelatin capsule, or compressed tablet form. 13. The therapeutic pharmaceutical composition of claim 8, wherein the analgesic is present in an amount of about 0.5 to about 25 percent by weight. 14. The therapeutic pharmaceutical composition of claim 8, wherein the analgesic is oxycodone or a pharmaceutically acceptable salt thereof. 15. A therapeutic pharmaceutical composition comprising: a mixture including (a) at least one opioid analgesic 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-acetylmethadol, levorphanol, lofentanil, meperidine, methadone, morphine, nalbuphine, oxycodone, oxymorphone, pentazocine, pethidine, propoxyphene, remifentanil, sufentanil, tilidine, tramadol and a pharmaceutically acceptable salt thereof; (b) gel forming polyethylene oxide; (c) at least one disintegrant wherein the disintegrant is selected from the group consisting of crospovidone, sodium starch glycolate, and croscarmellose sodium; and (d) sodium lauryl sulfate at about 1 to 10 percent by weight. 16. The therapeutic pharmaceutical composition of claim 15, further comprising an emetic. 17.
