Summary for Patent: 9,474,750
Title:Opioid agonist/opioid antagonist/acetaminophen combinations
Abstract: The invention is directed in part to oral dosage forms comprising a combination of an opioid agonist, acetaminophen and an orally active opioid antagonist, the opioid antagonist being included in a ratio to the opioid agonist to provide a combination product which is analgesically effective when the combination is administered orally, but which is aversive in a physically dependent subject. Preferably, the amount of opioid antagonist included in the combination product provides at least a mildly negative, "aversive" experience in physically dependent addicts (e.g., precipitated abstinence syndrome).
