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.

Particles comprising an opioid receptor antagonist as well as methods of their use and methods of their preparation are provided herein. Such particles may be used for treating and preventing opioid-induced side effects in patients, and may be provided to chronic opioid users as well.

Opioid receptors form functional heterodimers with each other and with other G-protein coupled receptors, such as dopamine receptors, adrenergic receptors, or chemokine receptors. These receptors can be exploited for high throughput screening of compounds to identify heterodimer opioid receptor modulators (agonists and antagonists). The invention also relates to identification of novel heterodimer receptor ligands and synergistic compositions, which can provide strategies for analgesia, narcotic addiction, hypertension, HIV infection, and immune system function.

The application is directed to compounds of Formula (I) and pharmaceutically acceptable salts and solvates thereof, wherein R¹, R², Y, Z, and G are defined as set forth in the specification. The invention is also directed to use of compounds of Formula (I), and pharmaceutically acceptable salts and solvates thereof, to treat disorders responsive to the modulation of one or more opioid receptors, or as synthetic intermediates. Certain compounds of the present invention are especially useful for treating pain.

The present invention relates generally to analgesic compounds having a mu opioid receptor agonist linked to a delta opioid receptor antagonist, and to methods for producing analgesia using such compounds. As compared to opioids such as morphine, these compounds can cause less tolerance, physical dependence, and/or constipation. These compounds are also more potent than morphine and are able to cross the blood brain barrier, thereby allowing for peripheral (e.g., IV) administration.

The present invention pertains to novel uses of endomorphine-1 peptide, analogs, and salts thereof for therapy of children, patients currently suffering from drug addiction, patients prone to opioid addiction, and patients with chemo-induced pain.

A topical opioid paradigm was developed to determine analgesic peripheral effects of morphine. Topical morphine as well as peptides such as [D-Ala2,MePhe4,Gly(ol)5]enkephalin (DAMGO) produced a potent, dose-dependent analgesia using the radiant heat tailflick assay. The topical drugs potentiated systemic agents, similar to the previously established synergy between peripheral and central sites of action. Local tolerance was rapidly produced by repeated daily topical exposure to morphine. Topical morphine tolerance was effectively blocked by the N-Methyl-D-Aspartate (NMDA) receptors antagonist MK801 and ketamine given either systemically or topically. NMDA receptor antagonists reversed pre-existing morphine tolerance. The activity of topical NMDA antagonists to block local morphine tolerance suggests that peripheral NMDA receptors mediate topical morphine tolerance. Morphine was cross tolerant to [D-Ala2,MePhe4,Gly(ol)5]enkephalin (DAMGO), but not to morphine-6 beta -glucuronide, implying different mechanisms of action. These observations have great importance in the design and use of opioids clinically. Topical pharmaceutical compositions comprising an analgesic that functions through an opiate receptor and an NMDA receptor antagonist for producing analgesia without inducing tolerance are described.

A dynorphin-A analog can be used for treatment, inhibition, and/or prevention of cocaine seeking behavior, and or the drug seeking behavior for a cocaine derivative or other structurally related substance. The dynorphin-A analog can be a cyclic dynorphin-A analog having sufficient systemic stability that crosses the blood-brain barrier so as to be active in the brain at kappa-opioid receptors (KOR) as an antagonist. Such activity at a KOR as an antagonist can be useful for cocaine management and reducing the desire, such as stress-related desires, for use of cocaine, crack, or the like. The KOR antagonist can be [N-benzylTyr¹,cyclo(D-Asp⁵,Dap⁸)]Dyn A-(1-11) amide, salt thereof, prodrug thereof, and/or derivative thereof.
