Bioanalytical techniques in discrimination between therapeutic and abusive use of drugs in sport.

In this paper, the strategies of discrimination and the analytical methods used for the main groups of substances where the distinction is needed (β-2 agonists, ephedrines, glucocorticoids and morphine) will be reviewed. Nowadays, LC-MS is the method of choice for the analysis of these substances and, in most of the cases, a simple dilution of the urine sample is performed before the chromatographic analysis.application/pdfengThis is the author's final version of the following article: Ventura R, Matabosch X, Segura J.
