  • Tamper resistant oral opioid agonist formulations
    Patent number: 10588865
    Abstract: Oral dosage forms containing an opioid antagonist in a sequestered form are described. The opioid antagonist is sequestered such that it is not released or substantially not released in the gastrointestinal tract from the dosage form which is administered orally intact. However, when the dosage form is chewed, crushed, heated or dissolved in a solvent, and then administered orally, intranasally, parenterally or sublingually, the opioid antagonist is released and at least partially blocks effects of the opioid agonist.
    Type: Grant
    Filed: June 5, 2019
    Date of Patent: March 17, 2020
    Assignee: Purdue Pharma L.P.
    Inventors: Benjamin Oshlack, Curtis Wright, J. David Haddox

  • Tamper-resistant oral opioid agonist formulations
    Patent number: 9456989
    Abstract: Methods of decreasing abuse potentials of oral opioid dosage forms are described. In the methods, an opioid antagonist in a substantially non-releasable form is included in oral dosage forms comprising an opioid agonist. When the dosage form is chewed, crushed, heated or dissolved in a solvent, and then administered orally, intranasally, parenterally or sublingually, the opioid antagonist is released and at least partially blocks effects of the opioid agonist. Methods of preparing oral opioid dosage forms having decreased abuse potential are also described.
