ANTICOAGULANT THERAPY Meaning and
Definition
-
Anticoagulant therapy refers to the medical treatment aimed at preventing the formation and growth of blood clots within the circulatory system. It involves the administration of medications known as anticoagulants that inhibit the coagulation or clotting of blood. The primary goal of anticoagulant therapy is to reduce the risk of thrombosis, which is the formation of abnormal blood clots that can obstruct blood vessels and cause serious complications.
Anticoagulant medications work by interfering with the blood's clotting mechanisms. They specifically target certain proteins involved in the clotting process, such as thrombin or factor Xa, to prevent the formation of fibrin, the insoluble protein that makes up blood clots. By inhibiting clot formation, anticoagulants help to maintain adequate blood flow through the vessels, preventing blockages that can lead to conditions such as deep vein thrombosis, pulmonary embolism, stroke, or heart attack.
Anticoagulant therapy is commonly prescribed for individuals diagnosed with venous thromboembolism (VTE), atrial fibrillation, or mechanical heart valve replacements. It may also be recommended for individuals undergoing certain medical procedures, such as major surgeries or dialysis, where the risk of blood clots is higher. The choice of anticoagulant medication and its dosage depends on various factors, including the patient's medical condition, age, weight, and potential interactions with other medications.
Regular monitoring of blood clotting factors, such as the international normalized ratio (INR) or activated partial thromboplastin time (aPTT), is essential during anticoagulant therapy to ensure that the prescribed medication is effectively working. Close medical supervision is recommended to prevent over-anticoagulation, which can lead to excessive
Etymology of ANTICOAGULANT THERAPY
The word anticoagulant originates from the Latin words anti meaning against or opposite and coagulans meaning clotting or congealing. Thus, anticoagulant literally means against coagulation or anti-clotting.
The term therapy on the other hand, comes from the Greek word therapeia, meaning healing or treatment.
