1. An oral dosage form comprising:
- (a) a therapeutically effective amount of an opioid analgesic selected from the group consisting of morphine, hydromorphone, hydrocodone, oxycodone, codeine, levorphanol, meperidine, dihydrocodeine, dihydromorphine, oxymorphone, pharmaceutically acceptable salts thereof and mixtures thereof;
(b) an agent selected from the group consisting of sugars, sugar derived alcohols, starch, starch derivatives, cellulose derivatives, attapulgites, bentonites, dextrins, alginates, carrageenan, gums, pectins, gelatin, kaolin, lecithin, magnesium aluminum silicate, carbomers carbopols, polyvinylpyrrolidone, polyethylene glycol, polyethylene oxide, polyvinyl alcohol, silicon dioxide, curdlan, furcelleran, egg white powder, lacto albumin, soy protein, chitosan, surfactants emylsifiers and mixtures thereof,wherein the ratio of the agent to the opioid analgesic is from about 1;
1 to about 30;
1 by weight,the opioid analgesic and the agent are dispersed in the same controlled release matrix comprising a controlled release material,the agent is in an effective amount to impart a viscosity to a mixture formed when the dosage form is crushed and mixed with from about 0.5 to about 10 ml of an aqueous liquid to render the mixture unsuitable for parenteral and nasal administration, andthe inclusion of the agent into the oral dosage form does not substantially change the dissolution rate of the opioid analgesic, as compared to said dosage form without the agent; and
(c) particles of a sequestered opioid antagonist, the particles consisting of the opioid antagonist, a hydrophobic material and one or more additional pharmaceutically acceptable excipients, whereinthe hydrophobic material is selected from the group consisting of a cellulose polymer, an acrylic polymer, a polylactic acid, polyglycolic acid and a copolymer of the polylactic and polyglycolic acid, and is in an effective amount to prevent the release of the antagonist from the dosage form which has been orally administered intact such that the antagonist is not released or substantially not released within 4, 8, 12 and 24 hours after the oral dosage form has been administered orally intactbut is released in an amount that will substantially block an analgesic effect of the opioid analgesic when the oral dosage form has been tampered with and administered orally, intranasally, parenterally or sublingually,the dosage form providing pain relief for at least about 12 hours when orally administered intact to a human patient.
