Abstract
Racehorses are commonly affected by a condition known as Exercise Induced Pulmonary Haemorrhage (EIPH) which consists of rupture of alveolar membranes and extravasation of blood into the airways. EIPH is considered to negatively affect racehorse performance and there is no current treatment. In order to reduce the amount of bleeding the diuretic furosemide has been used prior to exercise and competition in some racing jurisdictions. Efficacy of furosemide in reducing EIPH is documented in this research through endoscopic observation of the airways of horses positive for EIPH in two consecutive races.

Racehorses are commonly affected by a condition known as Exercise Induced Pulmonary Haemorrhage (EIPH) which consists of rupture of alveolar membranes and extravasation of blood into the airways
In Brazil, Thoroughbred racehorses are entitled to the use of FUR once they are endoscopically diagnosed as EIPH positive by authorized veterinarians
This study evaluated the efficacy of first time FUR use under competition circumstances by comparing endoscopies after two consecutive races
Summary
Racehorses are commonly affected by a condition known as Exercise Induced Pulmonary Haemorrhage (EIPH) which consists of rupture of alveolar membranes and extravasation of blood into the airways. Prophylaxis of Exercise Induced Pulmonary Haemorrhage (EIPH) with Furosemide (FUR) has become widespread, despite the fact that its results are questionable in efficiently and consistently controlling haemorrhage. In Brazil, Thoroughbred racehorses are entitled to the use of FUR once they are endoscopically diagnosed as EIPH positive by authorized veterinarians.
