商品名：Ventipulmin
Beta2-adrenergic agonist (beta2/beta1 ratio = 4.0). Bronchodilator. Stimulates beta2 receptors to relax bronchial smooth muscle. It also may inhibit release of inflammatory mediators, especially from mast cells. Compared to terbutaline, it has lower efficacy because of lower intrinsic activity, and it is only a partial agonist. Clenbuterol differs from other beta agonists because it resists O-sulfate ester conjugation, which produces a longer half-life. It also has better oral absorption (83%) than other beta agonists in horses. In horses, the plasma half-life is 13 hours, but in urine it can be detected for 12 days. In addition to the effects on respiratory smooth muscle, clenbuterol also can produce repartitioning effects, which indicates Clenbuterol 163 C that it will stimulate developm
Clenbuterol is indicated for treatment of animals with reversible bronchoconstriction such as horses with recurrent airway obstruction (RAO), formerly called chronic obstructive pulmonary disease (COPD). Studies have demonstrated effects in horses, but there are no reports of use in other species. In horses, it can have repartitioning effects (producing less fat), but it has also decreased exercise capacity and increased rate of fatigue. It should not be used in animals intended for food.
