increase in opioidergic tone (and thus no danger of a withdrawal syndrome if an opioid antagonist is given). Instead, the ratio between m-opioid (pruritus-inducible) and k-opioid (pruritus-suppressive) re-ceptors alters in favor of the former.69,70 This predisposes to the onset or exacerbation of pruritus.

An opposite shift of opioidergic function would also have to be considered in any treatment of a patient with fibromyalgia. These patients may be emotionally unresponsive due to an autoimmune hormonal disorder that diminishes opioid tone (Ramanathan et al., 2012; Johnson et al., 2014). Because the availability of social support is associated with beneficial effects on somatic health (Broadhead et al., 1983; Holt‐Lunstad et al., 2015), endogenous opioidergic tone might constitute an important protective factor for somatic well‐being via its links with prosocial behaviour and social attachment.

Aim To review and assess the efficacy of oral naltrexone for the treatment of cholestatic itch. 2018-09-27 · The opioid system is responsible for social pain and reward in the brain; therefore, understanding its underpinnings may help clinicians manage patients with depression and suicidal ideation. A central mechanism associated with increased opioidergic tone and involving activation of itch centres in the brain has been postulated.

Pruritus is a symptom of cholestasis, which appears to result, in part, from increased opioidergic tone; a central mechanism has been proposed. An opioidergic agent (or drug) is a chemical which functions to directly modulate the opioid neuropeptide systems (i.e., endorphin, enkephalin, dynorphin, nociceptin) in the body or brain. Examples include opioid analgesics such as morphine and opioid antagonists such as naloxone .

Following the naloxone administration in bile duct resected animals, striking opioid withdrawal signs are observed due to increased opioidergic tone. Pretreatment of animals with L-nitro arginine, a nitric oxide synthase inhibitor, reduces the naloxone-precipitated withdrawal signs as …

This may argue for an elevated opioidergic tone in the brain of athletes, mediating antinociceptive mechanisms. Opioids play a major role at descending pain modulation but the effects of neuropathic pain on the brain opioidergic system remain understudied. Since descending facilitation is enhanced during neuropathic pain, we studied the opioidergic modulation of the dorsal reticular nucleus (DRt), a medullary pain facilitatory area, in the spared nerve injury (SNI) model of neuropathic pain.

An opposite shift of opioidergic function would also have to be considered in any treatment of a patient with fibromyalgia.

central opioidergic tone contributes to the pruritus of cholestasis provide a rationale for treating this form of pruritus with opiate antagonists. However, initiation of therapy with an opiate antagonist in a cholestatic patient may precipitate a transient opioid withdrawal– like reaction. A …

Naltrexone behaves as an antagonist to endogenous and exogenous opioids, and also as an inverse agonist (thus this would be suitable for people who have low opioidergic/hedonic tone). 2020-09-23 · Sugar consumption promotes elevated opioidergic tone in the brain, and opioids inhibit synthesis and release of CRF and stress-induced HPA reactivity. 1995-05-01 · Re- printed with permission.11 tulated that increased opioidergic tone in cholestasis would be associated with opiate antagonist-reversible antinociception (in the absence of any exogenously ad- ministered opiate) and that an experimentally detectable manifestation of this phenomenon would be naloxone- reversible prolongation of tail-flick latencies in chole- static rats.

Dry cough, opioidergic tone, pruritus, paroxetine, serotonin Introduction Distressing persistent dry cough is commonly the consequence of sensitization of the cough reflex.

DOI The increase in opioidergic tone by the central administration of morphine, which binds to the mu opioid receptor, is associated with pruritus. Pruritus is a symptom of cholestasis, which appears to result, in part, from increased opioidergic tone; a central mechanism has been proposed. The single nucleotide polymorphism Al18G in exon 1 of the Opioidergic. Opioidergic descending pain control in the hypothalamus, PAG and RVM underlied placebo analgesia using MRI [173]. From: Peptides, 2010. Related terms: Neurotransmitter; Dopamine; Naloxone; Gonadotropin-Releasing Hormone; Beta-Endorphin; Serotonergic; Dopaminergic; Opioid Receptor; Opioid peptides However, the underlying mechanism for this observation remains elusive owing to the increased opioidergic tone detected in the transgenic model of AD, which would suggest a reduced sensitivity to exogenous opioid agonist, morphine (Smith and Yancey, 2003). Therefore, these results implicate a possible regulation of the opioidergic system in AD. Summary: The role of opioidergic system in controlling gonadotropin secretion in elderly men still remains uncertain.
