Description

Clenbuterol is agonist of beta2 adrenergic receptor. In some countries it is used as bronchodilator for treatment of asthma, but is not approved in USA. The drug is abused by bodybuilders and athletes for its ability to increase lean muscle mass and to reduce body fat. In 1998 FDA approved the clenbuterol-based Ventipulmin Syrup as a prescription-only drug for treatment of airway obstruction in horses.

Sample Use Guides

In Vivo Use Guide
For treatmen of airways obstruction the clenbuterol is administered orally, 15ml of syrop 2-3 times a day.
Route of Administration: Oral
In Vitro Use Guide
Affinity towards beta2 adrenergic receptors was measured using the recombinant receptor expressed in Sf-9 cells. Cell membrane homogenates were incubated with 0.15 nM of radioligand [3H]CGP1217 in the absence of presence of the clenbuterol. Following incubation, the samples were filtered rapidly under vacuum through through glass fiber filters, the filters were dried, and counted for radioactivity in a scintillation counter. Clenbuterol was binding to beta2 receptor with Ki of 0.58 uM.
