Lasix opponents have often argued that the diuretic can mask the presence of other drugs in a horse’s urine sample, a position that seemed to gain credence when the Seattle Mariners star Robinson Cano was banned for 80 games Tuesday because he tested positive for Lasix. Major League Baseball bans Lasix not because it believes it can improve a player’s performance, but because it believes it can mask other drugs that can. But two horse racing experts in the fields of Lasix, drug testing and the administration of drugs contacted by the TDN said that racing has virtually infallible safeguards in place to make sure that Lasix cannot hide the presence of performance-enhancing drugs in a horse’s system. “I am confident that the way we regulate Lasix does not materially affect our drug testing capabilities,” said Rick Arthur, the California Horse Racing Board’s equine medical director. “I’m not going to say it has no effect at all, but it is not a significant effect. With the rules that are in place, I don’t believe Lasix can be administered in a way that can manipulate a drug test.” Arthur explained that Lasix does not necessarily mask other drugs. Instead, because it is a diuretic, it causes the dilution of urine, which makes it harder to find other drugs in tests. “What that means is, let’s say because of Lasix your urine is twice as diluted. buy generic cialis professional One of the questions that we are frequently asked is, “What is the effect of Lasix on blood viscosity? Bleeds, or exercise induced pulmonary hemorrhages (EIPH), affect the majority of horses during intense exercise, and Lasix is often used to reduce or prevent bleeds. Lasix (or furosemide) is a potent loop diuretic that increases urine production and urinary frequency. Lasix has been administered to horses before races for the past 40 years as a way to reduce or prevent bleeds . Because Lasix reduces plasma volume, it is believed by many experts to reduce blood pressure in the lungs and prevent bleeds from occurring. Lasix has been shown to reduce plasma volume by 11-13%, and the effect lasts for up to 3-4 hours . Despite the reduced blood pressure and plasma volume in furosemide treated horses, veterinary researchers at the University of Pennsylvania stated, “Using a visual endoscopic scoring system, numerous studies conducted after racing have shown either a slight or no reduction in EIPH in horses administered furosemide before racing” . An authoritative review by equine veterinary scientists Lawrence Soma and Cornelius Uboh published in the Journal of Veterinary Pharmacology and Therapeutics stated that the reduction in blood pressure in the lungs caused by Lasix is not sufficient in magnitude to prevent bleeds .

It is believed that Dr. Alex Harthill first administered the medication to Northern Dancer prior to the 1964 Kentucky Derby. Lasix. When you hear the name the immediate response is to think of US racing, for it has long been the drug of choice that differentiates the American’s attitude to medication from other racing jurisdictions around the world. It is the common name for Furosemide, the anti-bleeding medication that burst into prominence in the 1970s. Racing.com's Senior Racing Journalist Shane Anderson looks at how well the use of Lasix - or Furosemide - is understood by the racing industry. When you hear the name the immediate response is to think of US racing, for it has long been the drug of choice that differentiates the American’s attitude to medication from other racing jurisdictions around the world. It is the common name for Furosemide, the anti-bleeding medication that burst into prominence in the 1970s. Yet, its use in Australian racing, is not widely known – or at least acknowledged. With the recent disqualification of Junoob from his victory in the Group 1 The Metropolitan at Randwick in October, and subsequent $30,000 fine to Sydney’s premier trainer Chris Waller for presenting the horse to race with a prohibited substance in his system, it has become apparent that Furosemide is being used in varying degrees throughout the Australian thoroughbred racing industry. If the use of Furosemide is banned on race day, then should it be allowed as a medication treatment at all? Bleeding in the lungs, which is now commonly referred to as Exercise Induced Pulmonary Haemorrhaging (EIPH), has long been an issue that has affected the racing industry. Horses, when placed under pressure during strenuous exercise, may bleed due to raised blood pressure in the lungs. This bleeding may then become present in the nostrils. The blood pressure leading from the artery on the right side of the heart to the lungs has a four-fold increase in horses during exercise or competition, a trait that would not exist in humans as an example. This pulmonary pressure increase means that the capillaries in horses’ lungs are prone to rupture. 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.
