| 摘要 |
The invention is directed in part to dosage forms comprising a combination of an analgesically effective amount of an opioid agonist analgesic and a neutral receptor binding agent or a partial mu-opioid agonist, the neutral receptor binding agent or partial mu-opioid agonist being included in a ratio to the opioid agonist analgesic to provide a combination product which is analgesically effective when the combination is administered as prescribed, but which is less analgesically effective or less rewarding when administered in excess of prescription. Preferably, the combination product affects an opioid dependent individual differently from an opioid naïve individual, and has a diminished likelihood of being associated with a life-threatening adverse drug reaction, especially in the opioid dependent individual.
