Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.

Acute toxic leucoencephalopathy following protonitazene ingestion

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Background Distribution of illicit counterfeit alprazolam containing the highly potent synthetic opioid‐receptor agonist protonitazene recently resulted in a number of severe overdoses in Ireland. We report three cases that presented to our hospital, within 6 weeks of one another, following ingestion of illicitly‐sourced alprazolam.

Altered Central μ-Opioid Receptor Binding After Psychological Trauma

open access: yes, 2007
Functional neuroimaging studies have detected abnormal limbic and paralimbic activation to emotional probes in posttraumatic stress disorder (PTSD), but few studies have examined neurochemical mechanisms that underlie functional alterations in regional ...

Rocavorexant, a novel, selective orexin‐1 receptor antagonist: Safety, tolerability and pharmacokinetics in healthy adults and individuals with opioid use disorder

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Rocavorexant (INDV‐2000), a selective orexin‐1 receptor antagonist, reduces drug self‐administration and anxiety in nonclinical studies. This Phase 1 programme evaluated the safety, pharmacokinetics and pharmacodynamics of rocavorexant in healthy volunteers and treatment‐seeking individuals with opioid use disorder (OUD).

The μ-opioid receptor differentiates two distinct human nociceptive populations relevant to clinical pain

open access: yesCell Reports Medicine
Summary: The shortfall in new analgesic agents is a major impediment to reducing reliance on opioid medications for control of severe pain. In both animals and man, attenuating nociceptive transmission from primary afferent neurons with a μ-opioid ...

The role of endogenous opioid neuropeptides in neurostimulation-driven analgesia

open access: yesFrontiers in Systems Neuroscience, 2022
Due to the prevalence of chronic pain worldwide, there is an urgent need to improve pain management strategies. While opioid drugs have long been used to treat chronic pain, their use is severely limited by adverse effects and abuse liability ...

Opioid Receptor [PDF]

open access: yes, 2022
Chronic pain and depression are both widely prevalent comorbid medical conditions. While efficient, μ-opioid receptor-based medications are associated with life-threatening side effects, including respiratory depression, dependence, and addiction.

Tramadol Co‐Administration with Oxycodone or Hydrocodone Increases Opioid Burden without Improving Postoperative Pain Control

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Tramadol is frequently co‐prescribed with oxycodone or hydrocodone after surgery under the assumption that its dual mechanism of action provides an opioid‐sparing benefit. However, evidence supporting this practice is limited and inconsistent. We conducted a secondary analysis of the multicenter IGNITE ADOPT‐PGx pragmatic trial of patients undergoing ...

Mechanistic insights into ligand selectivity in μ- and δ-opioid receptors beyond the “message–address” conceptual framework

open access: yesActa Pharmaceutica Sinica B
Ligand selectivity between μ-opioid receptors (μ-OR) and δ-opioid receptors (δ-OR) is key for improving opioid analgesics. While the “message–address” hypothesis has been central to explaining this selectivity, we present evidence for an additional ...
