| abstract |
Orally effective, analgetic compositions have been developed which are useful in the prevention of drug abuse because upon parenteral administration, they do not produce analgesia, euphoria, or physical dependence. Such compositions comprise an orally active, strong analgetic in oral dosage form and containing, for each analgetic dose of the analgetic agent, an amount of naloxone sufficient, upon parenteral administration of said oral dosage form, to negate the analgetic, euphoretic and dependence producing action of the composition, but insufficient to block the therapeutic effect of the analgetic when the admixture is taken orally. |
