clenbuterol
Clenbuterol (Spirovent, Ventipulmin) is a sympathomimetic amine used by sufferers of breathing disorders as a decongestant and bronchodilator. [1]
Alberto Contador will hold a press conference at a hotel in Spain Thursday and is expected to blame his positive test for Clenbuterol on food contamination. [2]
A World Anti-Doping Agency-accredited lab in Cologne, Germany, found a “very small concentration” of clenbuterol in Contador’s urine sample on July 21 at the Tour, according to a statement from the International Cycling Union (UCI). [3]
Recently though, the drug has been publicized for its off-label use as a weight loss drug, similar to usage of other sympathomimetic amines such as Ephedrine. [1]
Three-time Tour de France winner Alberto Contador tested positive for a banned steroid during this year’s race and has been suspended by cycling’s governing body. [...] Having invested millions of dollars in recent years in what is widely regarded as the one of the most stringent anti-doping regimes anywhere, cycling authorities hoped to be turning the corner on the widespread drug use by riders that had long made a mockery of the sport.

Professional cycling’s battered credibility took another devastating blow Wednesday night with revelations that the world’s best rider, Alberto Contador of Spain, tested positive for the banned substance Clenbuterol during his victorious ride at the Tour de France this summer. [2]
Jacinto Vidarte, Contador’s publicist, released a statement Wednesday saying the cyclist insists food contamination is the only possible explanation. [3]
The International Cycling Union, or UCI, which oversees professional cycling, issued a release saying that an anti-doping laboratory in Germany detected a minuscule amount of the drug (50 picograms), and that backup testing confirmed the finding. [...] If Tour de France organizers strip Contador of his most recent victory, he will be only the second cyclist in history to suffer such a fate - the first being Floyd Landis, who tested positive for testosterone in 2006 and was forced to relinquish his title. [...] This spring, Landis finally confessed to doping and leveled accusations at Armstrong and other cyclists that have become the subject of a federal investigation into Armstrong’s teams. [2]
There are also other informal reports on localized food contamination cases by clenbuterol in the U.S., which led to setting rules that limit consumption of this medicine only to horses. [...] It is also a non-steroidal anabolic and metabolism accelerator, through a mechanism not well understood. [...] A common trade name is Ventipulmin. [1]
