Farmaceutisk oral doseringsform omfattende en kombination af en opioidagonist og opioidantagonist

摘要

The invention is directed in part to oral dosage forms comprising a combination of an orally analgesically effective amount of an opioid agonist 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).
