The product contains the active ingredient clenbuterol hydrochloride, which is a sympathomimetic amine with a high degree of selectivity for the B2-receptor sites in the body, thus providing intense bronchodilating properties with minimum effect on the cardiovascular system. It has been shown to stimulate muco-ciliary clearance in horses.
The effects on pulmonary function and clinical response have been assessed in clinical trials with horses suffering from a variety of respiratory conditions.
A marked decrease in intrathoracic pressure, a decrease in respiratory rate, an initial decrease followed by an increase in arterial oxygen partial pressure and clinical improvements were observed. In addition, a significant reduction in resistance to airflow and a clinical improvement in the animals respiratory pattern were seen.
