Of all the questions posed to veterinarians by owners, the most common one concerns the use of Furosemide (Lasix). Lasix is one of the most discussed and sometimes controversial, yet least understood, drugs used in racing. For years, states argued over its use for treatment of exercise-induced pulmonary hemorrhage (EIPH) “bleeding”. Fortunately, in recent years the states have begun to agree on the dosage, route, and time of administration. Most notably, New York has finally approved its use in racehorses, which is scheduled to begin this fall. These events are due primarily to the efforts and recommendations of the American Association of Equine Practitioners. With the introduction of the flexible fiber optic endoscope, studies have shown that as much as 70% to 80% of horses have visible evidence of EIPH. One of the most controversial topics in Thoroughbred racing today is the race-day use of furosemide (commonly called Salix or Lasix). The drug is used to lessen the effects of a respiratory condition called exercise-induced pulmonary hemorrhage (EIPH), characterized by bleeding into the lungs or out the nose during exercise. In the midst of rumor and fact regarding the drug and the disease it treats, one professor offered an explanation. 2 Veterinary Science Seminar "Furosemide and EIPH: Efficacy and Controversy: The American Horsemen’s Story," held in Lexington, Ky., Thomas Tobin, MVB, MSc, Ph D, MRCVS, Dipl. ABT, professor of pharmacology and experimental therapeutics at the University of Kentucky Gluck Equine Research Center, reviewed the relationship between EIPH, furosemide, and the racehorse. EIPH and its Effects Tobin relayed that the phenomenon now known as EIPH was first recorded in the literature in the late 1700s when it was identified as epitaxis (bleeding from the nostrils) after intense exercise, and a decrease in performance. But it wasn’t until the fiber-optic endoscope was invented in the 1970s that veterinarians found that up to 80% of racehorses had evidence of blood in their tracheas after a race. Later, veterinarians learned a bronchoalveolar lavage will show evidence of bleeding at the alveolar capillary level. ACVIM, a professor at the Faculty of Veterinary Science at the University of Melbourne, Australia, described an EIPH scoring system that is currently used: "If you want to quantify the amount (or severity) of bleeding, you can do it visually," Tobin confirmed.

Because Salix — now more commonly known as Lasix — is a powerful diuretic when administered to a horse it causes the kidneys to increase urine production over and above the normal limit. As a result water is removed from the blood, not only in the lungs but also throughout the body. the liquid component of the blood that the red blood cells are suspended in) which in turn increases urine excretion, promotes dehydration, weight loss and electrolyte imbalances. How it helps counteract bleeding is by lowering blood pressure especially in the aorta and pulmonary artery which diminishes the problem of EIPH (Exercise-Induced Pulmonary Hemorrhage)  and returns performance to typical levels.  It is well known that due to the strenuous nature of the exercise involved in horse racing where Thoroughbreds can reach speeds of over 40 mph over the duration of 2 minutes or more, a majority of race horses will to some extent show bleeding in the lungs. Also known as Simple EIPH, the root cause of this acute, rather than chronic, problem is due to ruptured lung capillaries that release blood into the air passages of the lungs. Accordingly the air passageways can become obstructed which causes labored breathing and thus difficulty in running.  Because Salix prevents such bleeding in the lungs, it is arguably a performance enhancing drug. Medication use in horse racing has become a hot topic across the country. Uniform standards have been established by the Racing Medication and Testing Consortium (RMTC) for the United States. However, not all states are following these guidelines. The National Uniform Medication Program consists of medication rules, penalties, and testing guidelines. Additionally, the policy contains the Controlled Therapeutic Substances list, a policy limiting administration of furosemide to third-party veterinarians, a multiple medication violation penalty system, and a laboratory quality assurance program. Approved Controlled Therapeutic Medications The RMTC has established a list of 30 approved controlled therapeutic medications that have use for treating medical conditions in horses, along with withdrawal guidelines to avoid positive tests during races. It is important to note that administration of more than 1 medication can affect the time for the drug to leave the system, which can cause a positive drug test.
