Drug-drug interactions and masking effects in sport doping: influence of miconazole administration on the urinary concentrations of endogenous anabolic steroids

We have investigated the influence of oral miconazole administration on the urinary concentrations of endogenous anabolic androgenic steroids of doping relevance, specifically considering all these compounds routinely monitored in doping control analysis, in the framework of the steroidal module of the “athlete biological passport”, and other steroids, including dehydroepiandrosterone, 5α-dihydrotestosterone, and the hydroxylated metabolites...
