Thrombosis is the condition where an imbalance in the homeostatic mechanism results in unwanted intravascular thrombus formation. Imbalances in this highly regulated process of coagulation and anticoagulation can lead to a variety of pathophysiological conditions leading to stroke, pulmonary heart attack and other serious conditions. In the western world, thromboembolic diseases are the leading cause of morbidity and mortality. Remarkable progress has occurred over the last decade in the development of antithrombotic drugs, which can be classified into 3 major categories – Anticoagulants, Antiplatelets and thrombolytics. Increased understanding of the pathobiology of thrombotic and vascular disorders has helped researchers to target novel pathways involving the coagulation, thrombolytic, fibrinolytic and integrin systems. Traditionally aspirin and unfractionated heparin was used for myocardial infarction. Newer antiplatelet agents such as, clopidogrel, GP IIb/IIIa inhibitors, low molecular weight heparin, direct thrombin inhibitors and several improved thrombolytic agents have been introduced for clinical use. This review will discuss different important drugs, which have been launched in recent years and also some new targets pursued by different companies.
