Administration Studies in Equine Antidoping Research: Designing Scientific Investigations to Effectively Direct Medication Control in Racehorses

open access: yesDrug Testing and Analysis, EarlyView.
ABSTRACT Pharmacokinetics is the study of the movement of drug in the body and includes the processes of absorption, distribution, metabolism, and excretion. Pharmacodynamics is the pharmacologic effect of the drug on the body. The pharmacokinetics of a drug determines its pharmacologic effect. Pharmacokinetic studies describe drug concentrations while

Impact of Menstrual Cycle and Oral Contraceptives on Haematological and Inflammatory Biomarkers in Highly Trained Female Athletes

open access: yesDrug Testing and Analysis, EarlyView.
In highly trained female athletes, haematological and inflammatory biomarkers were found to be independent of menstrual cycle phase, but oral contraceptive use increased transferrin, reticulocyte count and triglycerides and decreased interleukin‐6.

Workplace Drug Testing—Prevalence of Positive Test Results, Most Common Substances, and Importance of Medical Review

open access: yesDrug Testing and Analysis, EarlyView.
Among 23,900 urine and oral fluid drug tests from Swedish workplaces, 4.6% tested positive for controlled substances. Cannabis, amphetamine, cocaine and benzodiazepines were most common. Many samples containing opiates, amphetamine or benzodiazepines were MRO verified as being due to medical prescriptions, while cannabis or cocaine were almost entirely

Screening and Quantification of the Synthetic Cannabinoid Receptor Agonist 5F‐MDMB‐PINACA From Seized Prison Paper Using Ultraperformance Liquid Chromatography–Mass Spectrometry Approaches

open access: yesDrug Testing and Analysis, EarlyView.
Synthetic cannabinoid receptor agonists are being infused on paper and illicitly introduced into prisons through mail correspondence. An approach to quantify and map the synthetic cannabinoid 5F‐ADB on a seized paper sample from a UK prison was determined using ultraperformance liquid chromatography–quadrupole Dalton–mass spectrometry.
