Sure. Okay.
Edit: for those that think there's no research on lasix in racehorses
PubMed.
http://www.ncbi.nlm.nih.gov/sites/entrez "furosemide" "equine" 173 hits. That's only the past seven years, not all years of published research previous to that - basic pharmacokinetics, initial use in the racing industry - is available online, one has to look it up the old-fashioned way. Some examples:
Pharmacokinetics and pharmacodynamics of furosemide after oral administration to horses.
Detection, quantification, and pharmacokinetics of furosemide and its effects on urinary specific gravity following IV administration to horses.
Comparison of serum and urinary concentrations of clenbuterol with and without concomitant administration of furosemide in horses.
Detection of bicarbonate administration (milkshake) in standardbred horses.
Doping in race horses.
Factors influencing pre-race serum concentration of total carbon dioxide in Thoroughbred horses racing in California.
A direct enzyme immunoassay for the measurement of furosemide in horse plasma.
Questions effect of furosemide on racing Thoroughbreds.
