CYP2D6‐Guided Opioid Therapy for Chronic Pain: A Multi‐Center Pragmatic Randomized Controlled Trial

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
The analgesic effectiveness of several opioids depends on CYP2D6‐mediated metabolism to more active opioid receptor agonists. CYP2D6 activity is impacted by genetic variability and medications that inhibit CYP2D6. We conducted a pragmatic, multi‐center, randomized, controlled trial to determine whether CYP2D6‐guided opioid prescribing improves chronic ...

Medication Use During Breastfeeding—An Understudied Population: A Five‐Year Experience in the Pharmacovigilance Center of Lyon

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Medication use during breastfeeding is common, yet data on drug transfer into breast milk and infant exposure remain limited. This study describes real‐world requests concerning medication compatibility with breastfeeding managed by the Lyon pharmacovigilance center over five years.

Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

open access: yesDrug Testing and Analysis, EarlyView.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

Regulation of c-jun n-terminal kinases by opioid receptors

open access: yes, 2002
In mammals, the G protein-coupled opioid receptors are mainly expressed in the central nervous system, and early pharmacological studies on immunocytes indicate that the classical δ-, μ- and κ-opioid receptors are also present in platelets, lymphocytes ...

First Occurrence of Fatal Intoxication Involving Methiodone (IC‐26) in Finland; a Medicolegal Autopsy Case Report

open access: yesDrug Testing and Analysis, EarlyView.
ABSTRACT Methiodone (IC‐26) is a non‐fentanyl novel synthetic opioid which has recently been detected in drug seizures in Europe. There is still limited data about the drug in published toxicological case work, both in non‐fatal and fatal cases. We present a medicolegal autopsy case report on a fatal intoxication in an individual undergoing opioid ...

The roles of opioid receptors and agonists in health and disease conditions [PDF]

open access: yes, 2011
Opioid receptors are found in the central nervous system (CNS) and are classified as mu (µ), kappa (κ), delta (δ) and sigma (σ) opioid receptors. Opioid receptors belong to the large family of G protein coupled receptors (GPCRs), and have diverse and ...

Population‐Stratified Distributions of Post‐Mortem Blood Drug Concentrations: An Epidemiological Framework for Contextual Interpretation

open access: yesDrug Testing and Analysis, EarlyView.
Post‐mortem blood drug concentrations exhibit substantial overlap between deaths in which a drug was implicated and those in which it was not. Analysis of over 58,000 NPSUM cases demonstrates that demographic stratification does not resolve this uncertainty, reinforcing the need for contextual, evidence‐based interpretation rather than concentration ...

Intra‐Individual Variability of Blood and Urinary Steroid Markers and the Response to Codeine Intake in Healthy Men and Women

open access: yesDrug Testing and Analysis, EarlyView.
Short‐term codeine administration (1–3 days) caused individual alterations in Athlete Biological Passport steroid markers, including elevated urinary T/E ratios and decreased serum testosterone concentrations below individual thresholds, despite no significant changes at the group level.
