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).

Disclosed in certain embodiments is an oral dosage form comprising a therapeutically effective amount of an opioid analgesic, an opioid antagonist and one or more pharmaceutically acceptable excipients; the dosage form further including a gelling agent in an effective amount to impart a viscosity unsuitable for administration selected from the group consisting of parenteral and nasal administration to a solubilized mixture formed when the dosage form is crushed and mixed with from about 0.5 to about 10 ml of an aqueous liquid.

An analgesic composition is disclosed comprising a sub-analgesic dosage of a mu-opioid agonist, optionally in the form of a pharmaceutically acceptable salt, and a sub-analgesic dosage of a kappa2-opioid agonist, optionally in the form of a pharmaceutically acceptable salt. There is also disclosed a method for producing analgesia in humans and lower animals which comprises administering concurrently to a human or lower animal in need of such treatment an analgesic composition of the invention.

A pain relief lollipop comprises a candy matrix comprising (a) an opioid agonist, (b) an N-methyl-D-aspartate receptor antagonist different from the opioid agonist, (c) gabapentin, or a pharmaceutically acceptable salt thereof, and, optionally, a muscle relaxant, sedative, anxiolytic, and/or antidepressant. A patient can self-administer small amounts of the pain relief drug as needed by simply licking or sucking on the lollipop in response to his subjective experience of pain.

This invention relates to a method of selectively enhancing the analgesic potency of morphine and other clinically used bimodally-acting opioid agonists and simultaneously attenuating development of physical dependence, tolerance and other undesirable side effects caused by the chronic administration of said bimodally-acting opioid agonists comprising the co-administration of a bimodally-acting opioid agonist which activates both inhibitory and excitatory opioid receptor-mediated functions of neurons in the nociceptive (pain) pathways of the nervous system and an opioid receptor antagonist which selectively inactivates excitatory opioid receptor-mediated side effects. This invention also relates to a method of using excitatory opioid receptor antagonists alone to block the undesirable excitatory side effects of endogenous bimodally-acting opioid agonists which may be markedly elevated during chronic pain. This invention further relates to a method of long-term treatment of previously detoxified opiate, cocaine and alcohol addicts utilizing said excitatory opioid receptor antagonists, either alone or in combination with low-dose methadone, to prevent protracted physical dependence, and to compositions comprising an excitatory opioid receptor antagonist of the invention and a bimodally-acting opioid agonist.

Methods and compositions for treating subjects with pain, including neuropathic pain, using opioid antagonists or combinations of opioid antagonists and opioid agonists, including, for example, wherein the amount of an opioid antagonist enhances the neuropathic pain-alleviating potency of an opioid agonist.

Methods and materials, including novel compositions, dosage forms and methods of administration, useful for treating arthritic conditions, inflammation associated with a chronic condition, and/or chronic pain, including pain from arthritis and inflammation, using opioid antagonists, including combinations of opioid antagonists and opioid agonists. Methods and materials comprising opioid antagonists or combinations opioid antagonists and agonists may optionally include one or more additional therapeutic agents.

The present invention provides abuse-resistant transdermal delivery devices containing an opioid agonist intended for analgesic purposes in pain patients.

Disclosed in certain embodiments is an oral dosage form comprising a therapeutically effective amount of an opioid analgesic, an opioid antagonist and one or more pharmaceutically acceptable excipients; the dosage form further including a gelling agent in an effective amount to impart a viscosity unsuitable for administration selected from the group consisting of parenteral and nasal administration to a solubilized mixture formed when the dosage form is crushed and mixed with from about 0.5 to about 10 ml of an aqueous liquid.

The present invention provides a dosage form, particularly a tamper resistant dosage form, comprising; non-stretched melt extruded particulates comprising a drug selected from an opioid agonist, a tranquilizer, a CNS depressant, a CNS stimulant or a sedative hypnotic; and a matrix; wherein said melt extruded particulates are present as a discontinuous phase in said matrix.

The present invention provides a composition comprising an opioid agonist, and a polymer-antagonist conjugate. The polymer-antagonist conjugate preferably does not hydrolyze upon administration to a patient, and does not bind to the opioid receptors. The covalent bond between the polymer and the antagonist in the conjugate is broken over a defined period of time to release the antagonist into the formulation. The released antagonist attenuates the liking of the agonist, thereby eliminating the incentive to the diversion of the medicines.
