Amicar is used to induce clotting and in the scenario you guys are discussung I would think this is pretty risky because clotting would take place everywhere not just in the lungs where the "bleeding" is supposed to take place.

There isn't good documented efficacy supporting it's use as an anti-fibrinolytic.

As an aside I have always been skeptical of "bleeding" taking place in horses lungs but rather the human equivalent of pulmonary edema which "looks like bleeding" the lasix both increases capacitance (pipe size thus more pipe less bleeding but also causes urination through a "loop of Henle" mechanism) or the highest and most effacious way to move water fast.

Give pre-exercise, yes, the goal of lasix is to lower pulmonary artery pressure.

Doc, PM me and send me your e-mail, I'll send you a couple of good summary articles on current thoughts for possible causes of EIPH in the horse (other than strict stress failure of pulmonary capillaries secondary to increased Ppa) and treatments.
