Ticagrelor: a novel drug for an old problem.

Abstract

Cardiovascular disease and in particular, acute coronary syndromes are one of the principle causes of death in the industrialized countries. In the setting of acute coronary syndromes (both ST - segment or non ST - segment elevation myocardial infarction), platelets aggregation plays a key and central role in their development. Platelets are the mediators of hemostasis at sites of vascular injury, but they also mediate pathologic thrombosis; activated platelets stimulate thrombus formation in response to rupture of an atherosclerotic plaque or endothelial cell erosion promoting atherothrombotic disease. Recent patent relates to the methods and devices for treating atherosclerosis and to prevent in-stent restenosis or thrombosis. Because of the importance of platelets involvement in the initiation and propagation of thrombosis, antiplatelet drugs have a source of research; in the recent past, new antiplatelet drugs (such as ticagrelor) have been studied and placed in the routine therapy. The aim of this paper is to summarize the pharmacological properties and the clinical characteristics of ticagrelor.
