Why use lasix on race horses?

Answer 1

Some horses have nose bleeds when given strenous excercise, so they ar given lasix to lower their blood pressure reducing the possiblity of the nose bleeds. It is done to improve the publics view of horse racing, not because the horse is in any real danger from the nose bleeds. I just doesn't do the racing industry any good to see a horse in the winner circle with blood dripping from a nose bleed or bloody frothy foam around the mouth and nostrils.
