What respiratory disease is often treated with Lasix in horses?

Exercise-induced Pulmonary Hemorrhage (EIPH) is the respiratory disease frequently treated with Lasix in horses. EIPH occurs when blood vessels in the lungs rupture during intense physical exertion, often leading to the presence of blood in the horse's airways. Lasix, a diuretic, is commonly administered to help reduce blood pressure within the lungs, thus reducing the risk of further bleeding. By alleviating the excess fluid buildup in the tissues and promoting better lung function, Lasix plays a vital role in the management of this condition, especially in racehorses.

Conversely, while asthma (often referred to as heaves in horses) is a respiratory condition that might involve the use of bronchodilators, it is not treated with Lasix. Strangles, a bacterial infection, primarily affects the lymph nodes and is typically treated with antibiotics rather than diuretics. Colic refers to abdominal pain and would require different approaches for treatment, including pain management and sometimes surgery, making it unrelated to the use of Lasix.
