Anticoagulant - Definition

Ask a question


Coagulation is the transformation of a liquid substance into a substance more or less solid. In the blood, it occurs in several stages which allow the formation of a blood clot. An anticoagulant allows us to slow down excessive coagulation. It's a medication used under close medical observation. It allows the blood to be thinned and prevents the formation of clots. Anticoagulants are prescribed in the case of phlebitis, pulmonary embolism, lack of adequate blood circulation, or heart failure. Two kinds of anticoagulants are used in medicine: heparins, fast-acting anticoagulants, which aren't recommended very often for use over extended periods of time, and the vitamin K antagonists, commonly called VKA, which act more slowly, but can be taken in the long-term.
