Kentucky Equine Research Releases Lasix Study Results

Kentucky Equine Research (KER) has released a technical bulletin, titled “Furosemide Use in Racehorses: A Nutritional Perspective,” summarizing research on the use of furosemide, performed both by KER and independent scientists.

Approximately 90% of Thoroughbreds and 70% of Standardbreds are treated with furosemide (known as Lasix or Salix) prior to competition. Use of the drug is also becoming prevalent in barrel racing. KER performed a series of studies on furosemide use, tracking the effects of the drug on body weight, water consumption and mineral losses, as well as recovery time. The results of these studies are summarized in the technical bulletin.

To improve weight recovery and replace these mineral losses, KER developed a two-stage electrolyte program called Race Recovery. Race Recovery Paste is used immediately after racing and serves to stimulate thirst and hasten body-weight recovery. KER studies have shown that horses had a 17% increase in 24-hour water intake and a 30% improvement in body-weight rebound when given Race Recovery Paste compared to control horses. Race Recovery Powder is fortified with highly bioavailable sources of electrolytes and minerals. KER balance trials have shown that Race Recovery Powder is effective in replacing electrolytes, including calcium and magnesium, lost in sweat and urine in exercised horses treated with furosemide.

Race Recovery is the newest addition to the KERx line of special-needs supplements developed by KER. The range of products addresses commonplace conditions like obesity and gastrointestinal health as well as complex problems like tying-up and bone demineralization. Backed by science and preferred by veterinarians, KERx products are designed with one goal in mind: to optimize horse health.
