Codeine toxicity via breast Milk: Can this occur and implications for opiate therapy in children

British Journal of Clinical Pharmacology, EarlyView.
Codeine is commonly used in combination analgesic products. The use of codeine during breastfeeding can rarely be associated with serious adverse effects related to genetic polymorphisms affecting codeine's metabolism and disposition. Clinicians treating infants of breastfeeding mothers should be aware of this rare but potentially serious complication.

Dual Effect of Glucuronidation of a Pyrogallol-Type Phytophenol Antioxidant: A Comparison between Scutellarein and Scutellarin

Molecules, 2018
To explore whether and how glucuronidation affects pyrogallol-type phytophenols, scutellarein and scutellarin (scutellarein-7-O-glucuronide) were comparatively investigated using a set of antioxidant analyses, including spectrophotometric analysis, UV ...

In vitro metabolism, reaction phenotyping, enzyme kinetics, CYP inhibition and induction potential of ataluren

Pharmacology Research & Perspectives, 2020
Ataluren promotes ribosomal readthrough of premature termination codons in mRNA which result from nonsense mutations. In vitro studies were performed to characterize the metabolism and enzyme kinetics of ataluren and its interaction potential with CYP ...

The Glycosyltransferase Pathway: An Integrated Analysis of the Cell Metabolome

Metabolites, 2022
Nucleotide sugar-dependent glycosyltransferases (UGTs) are critical to the homeostasis of endogenous metabolites and the detoxification of xenobiotics. Their impact on the cell metabolome remains unknown.

Virtual Twin Approach Using Physiologically Based Pharmacokinetic Modeling to Support Precision Dosing of Valproic Acid in Geriatric Patients

Clinical Pharmacology &Therapeutics, EarlyView.
Personalized dosing is particularly important for drugs with narrow therapeutic indices in geriatric patients, who exhibit substantial physiological variability and limited pharmacokinetic (PK) evidence to guide individualized dose selection. Valproic acid (VPA) is an effective treatment option for bipolar disorder in older adults, yet dosing largely ...

Gas Chromatography of Glucuronides.

Chemical and Pharmaceutical Bulletin, 1967
The applicability of gas chromatography to the analysis of various types of glucuronides including ether-, ester-, N-and S-glucuronides was studied by converting them to acetyl, methyl and trimethylsilyl derivatives.

Payload‐Based Clinical Pharmacology Review of Approved Antibody–Drug Conjugates: Commonalities and Considerations for Streamlined Development

Clinical Pharmacology &Therapeutics, EarlyView.
Antibody–drug conjugates (ADCs) combine the specificity of an antibody with the potency of a cytotoxic drug. Thirteen ADCs, utilizing seven unique cytotoxic payloads and targeting 11 distinct antigens, are currently approved by the US Food and Drug Administration as of June 2025, representing a rapidly growing and highly promising class of anticancer ...

Investigation of the In Vitro and In Vivo Metabolism and μ‐Opioid Receptor Affinity of the Nitazene N‐Pyrrolidino Fluetonitazene

Drug Testing and Analysis, EarlyView.
Eight metabolites for N‐pyrrolidino fluetonitazene were identified in vitro, three of which (M2, M6 and M8) were present in an authentic urine sample. M2 was the most abundant in vivo metabolite and is a common marker metabolite of nitazepyne‐type substances.

Phase I Metabolism of Novel Phencyclidine Derivative 3‐Cl‐PCP: In Vitro Studies With Pooled Human Liver Microsomes and Investigation of a Post‐Mortem Case

Drug Testing and Analysis, EarlyView.
A fatal 3‐chloro‐phencyclidine (3‐Cl‐PCP) intoxication was investigated by analyzing postmortem samples and a pooled human liver microsomes assay. Tentative metabolite identification was performed by liquid chromatography‐quadrupole time‐of‐flight mass spectrometry (LC‐QTOF‐MS). Seven phase I metabolites were identified.

In Vitro Metabolism of Δ8‐, Δ9‐, and Δ10‐THC in Human Hepatocytes: Distinct Δ10‐THC Biotransformation and Implications for Drug Testing

Drug Testing and Analysis, EarlyView.
Δ8‐THC and Δ9‐THC showed comparable metabolic profiles. In contrast, Δ10‐THC underwent extensive glucuronidation and hydroxylation, with only minor formation of a carboxy metabolite, indicating a markedly different metabolic pathway. These differences may increase the risk of misidentification and misinterpretation in cannabis drug testing.
