Antiplatelet therapy by acetylsalicylic acid (ASA, aspirin) provided pivotal advances in the prevention and treatment of organovascular (angiovascular, cardiovascular, cerebrovascular, extremitovascular, renovascular, genitovascular, mesenteriointestinokolonovascular, bronchopulmovascular, oculovascular, otovascular and other) arterial ischemic diseases. Currently available antiplatelet drugs have some limitations which might be overcomed by improved dosing regimens, use of combination of agents affecting different platelet functions and, in particular, by the new antiplatelet drugs (new arterial antithrombotics) with distinct pharmacodynamic properties offering new advantages, including faster onset of action, greater potency, and reversibility of effects.Key words: arteriothromboprophylaxis - arterial thrombosis - classic antiplatelet drugs - new antiplatelet agents - organovascular arterial diseases.
