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

Drug 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 ...

An Investigation Into the Yields of 3,4‐Methylenedioxyphenyl‐2‐propanone (MDP2P) From Glycidate Pre‐Precursors

Drug Testing and Analysis, EarlyView.
Hydrolysis of the glycidate pre‐precursors MMDMG and EMDMG was evaluated for MDP2P production. Acid hydrolysis of MMDMG (HCl, 100°C, 18 h) yielded the highest MDP2P recovery (79%), whereas base hydrolysis produced only slightly lower yields (73%), demonstrating both pathways are effective routes to this key MDMA precursor.

Population Pharmacokinetics and Detection Times of Betamethasone After Intravenous, Intramuscular, and Intranasal Jet Administration of Betamethasone Sodium Phosphate in Horses

Drug Testing and Analysis, EarlyView.
Betamethasone concentrations in 20 horses from Japan and Germany following IV, IM, and INJ administration of betamethasone phosphate were analyzed using population pharmacokinetic modeling. For IV administration of 0.04 mg/kg q24 h, IPC and IUC were 0.012 and 0.31 ng/mL, respectively; the IUC approximated the IFHA urine ISL (0.20 ng/mL).

Comprehensive Evaluation of Commercial Antibodies for High Sensitivity Detection of EPO‐Doping on Western Blots

Drug Testing and Analysis, EarlyView.
A large‐scale evaluation of 164 commercially available anti‐human EPO antibodies was conducted to identify an alternative to clone AE7A5 anti‐EPO antibody used in doping control for the detection of erythropoiesis‐stimulating agents (ERAs) on Western blots.

Simultaneous Detection of Steroid Esters and Multi‐Class Substances in Dried Blood Spots by LC‐HRMS/MS From a Single Spot for Human Doping Control

Drug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled, for the first time, the comprehensive detection of steroid esters and multi‐class menu substances from a single dried blood spot. Following extraction, the resulting extract is split into two aliquots, reducing sample consumption and simplifying the analytical workflow.
