Effect of thrombin inhibitors and a glycoprotein IIb/IIIa receptor antagonist in an ex vivo human experimental thrombosis model.

The development of new antithrombotic drugs to inhibit the blood coagulation system and to block receptors of platelets represents an important area of medical research. The results of the efficacy in animal models are of critical importance for the further development of these compounds for human use. The transferability of such data from animal to human species still remains controversial. The antithrombotic effects of direct thrombin inhibitors and a glycoprotein IIb/IIIa (GPIIb/IIIa) receptor antagonist were investigated in an experimental thrombosis model using human blood in order to analyze the feasibility of such a model.
