This video features ESPN’s Greg Gumbel and Sharon Smith reporting on the use of the drub Lasix in horse racing….and how its use is not allowed at the 1986 Kentucky Derby. Furosemide, sold under the brand name Lasix, is a medication used to treat fluid build-up due to heart failure, liver scarring, or kidney disease….which is also used for the treatment of high blood pressure….which can be taken intravenously or by mouth. When taken by mouth, it typically begins working within an hour….while intravenously, it typically begins working within five minutes. Lasix is a type of loop diuretic that works by decreasing the re-absorption of sodium by the kidneys…..which when used in horse racing reduces the chances of bleeding in the lungs during a race. Lasix is specifically outlawed at this 1986 Kentucky Derby….as specified in the official program and betting line.
