Metformin in the Horse: Pharmacokinetics and Detection Times Using Monte Carlo Simulations

open access: yesDrug Testing and Analysis, EarlyView.
In recent years, the detection of metformin in blood and urine samples collected from racehorses has raised concern among regulators. This study describes blood and urine concentrations and the pharmacokinetics of metformin following IV and oral administration to horses. Data presented here can be used to establish screening limits and withdrawal times

Further Insights Into the Metabolism of LGD‐4033 in Human Urine. Part 2. A New Minor Metabolite With Antagonistic Activity on the Androgen Receptor Can Indicate Recent Substance Intake

open access: yesDrug Testing and Analysis, EarlyView.
A novel early excreted minor metabolite of LGD‐4033 was detected and coded as M8. Its presence was evaluated as an indicator of recent substance intake versus end‐tail findings. Additionally, the agonist/antagonist properties of M8 and other selected LGD‐4033 metabolites on the androgen receptor (AR) were studied using in silico molecular docking and ...

Improvement of EPO Transgene Detection From Polymeric Dried Blood Spots for Antidoping Application

open access: yesDrug Testing and Analysis, EarlyView.
This article presents an optimized protocol for gene doping detection. Starting from one spot DBS (20 μL), concentrated DNA was obtained and real‐time PCR parameters were adjusted for increased detection. Robust detection of 5000 copies/mL of transgene was validated for polymeric device TASSO M‐20.
