Detection of main urinary metabolites of β2-agonists clenbuterol, salbutamol and terbutaline by liquid chromatography high resolution mass spectrometry

Clenbuterol, terbutaline and salbutamol are B2-agonists drugs included in the list of banned substances of the World Anti Doping Agency (WADA) prohibited in and out of competition. In this article, the excretion of urinary metabolites of clenbuterol, terbutaline and salbutamol have been studied using liquid chromatography electrospray time-of-flight mass spectrometry (LC-TOFMS), after a single therapeutic dose administration in rats.
