Abstract
Disclosed herein are oral dosage forms of opioid therapeutic agents that are resistant to abuse and methods of their formulation. In particular, oral dosage forms that are resistant to dissolution in aqueous solutions of ethanol are described. The oral dosage forms may include one or more opioid antagonists that are sequestered from the opioid therapeutic agent such that the opioid antagonist has no substantial effect on the activity of the opioid therapeutic agent when the dosage form is taken orally as prescribed, but the opioid antagonist is released in an amount that reduces the effectiveness of the opioid therapeutic agent contained in the dosage form when the dosage form is crushed.
