Experimental studies on the antithrombotic action of a highly effective synthetic thrombin inhibitor

The antithrombotic action of the highly effective synthetic thrombin inhibitor N alpha-(2-naphthylsulfonylglycyl)-4-amidinophenylalanine piperidide was studied in various models of experimental thrombosis in rats. Intravenous infusion of the thrombin inhibitor caused a dose-dependent inhibition or prevention of stasis-induced venous thrombosis, of arterial thrombosis after electrically-induced damage of the vessel wall and of thrombotic occlusion of an extracorporeal arterio-venous shunt.
