The pharmacodynamics and pharmacokinetics of hirudin were studied in dogs, rabbits
and rats. Hirudin proved to be a well tolerated substance with low toxicity. After
intravenous injection it was eliminated with a half time of 50 to 60 min. It was nearly
completely excreted through the kidneys in biologically active form. The efficacy
of hirudin in preventing venous thrombosis, vascular shunt occlusion and disseminated
intravascular coagulation in rats was demonstrated.
