Clenbuterol

Clenbuterol belongs to the group of ß-agonists. In livestock production clenbuterol improves the meat/fat ratio in fattened animals or accelerate the growth. Up to now ß-agonists have not been authorized as adjuvants for fattening.

In addition to its lipolytic and anabolic effect, clenbuterol has a relaxing effect on non-striated musculature on which is based its therapeutic use as an antiasthmatic and a tocolytic agent. When employed as a fattening adjuvant, as compared with the therapeutic use, clenbuterol is administered in a 5 to 10 times higher dose.

Therefore, it is possible that clenbuterol residues may lead to a risk for consumers after illegal administration.

Using the RIDASCREEN® Clenbuterol assay, it is possible to detect clenbuterol and other ß-agonists in urine, muscle, liver and cattle eyeball both rapidly and with accuracy.
