#thrombosis

• Anticoagulant — Preventing, delaying, or halting the blood clotting process; a medication, biological substance, or chemical compound (such as heparin or coumarin derivatives) clinically utilized to prevent and treat thrombosis, pulmonary embolism, and other vascular cardiovascular conditions by reducing blood clot formation.
• Anti-thrombus — A rare or figurative medical term designating a pharmaceutical preparation, a monoclonal antibody, an endovascular device, or a biological mechanism specifically designed to counteract, dissolve, or prevent the formation of a thrombus (blood clot) within the lumen of blood vessels. It is sometimes used in clinical jargon to describe an active protective barrier against acute thrombosis.
• Antithrombin — A plasma glycoprotein synthesized by the liver, playing the major physiological role of inhibiting coagulation enzymes, specifically thrombin and factor Xa, thereby preventing the formation of parasitic blood clots. Clinically designated as antithrombin III, this macromolecule represents the most important natural anticoagulant in the human body, its efficiency being exponentially amplified by heparin, which is why its hereditary deficiency dramatically increases the risk of venous thromboembolism.
• Antithrombotic — An abstract medical term or a historical/experimental trade name designating an active substance, a synthetic antibody, or a biochemical compound capable of inhibiting the process of intravascular thrombosis. This macromolecule acts by specifically blocking platelet membrane receptors or by neutralizing enzymatic factors within the coagulation cascade, with the ultimate goal of preventing the obstruction of large blood vessels.
