Cimbuterol is primarily used in veterinary medicine as a bronchodilator to treat respiratory conditions in animals, particularly horses. It helps to relax the muscles in the airways, making it easier for animals to breathe, especially in cases of asthma or chronic obstructive pulmonary disease (COPD). Additionally, it has been explored for its potential to promote muscle growth and reduce fat, leading to its misuse as a performance-enhancing agent in livestock. However, its use in food-producing animals is highly regulated or banned in many countries due to potential health risks to humans consuming treated animal products.
