Warfarin

Warfarin

Properties

This medicine contains a heparin-like substance as active ingredient. It is a drug that affects blood clotting (anticoagulant drug). Blood clots normally form only as a response to injury. In some people, however, there is a tendency for clots to form in the blood vessels without apparent  cause.

Disturbed blood flow occurring as a result of the presence of fatty  deposits – atheroma – inside the blood vessels increases the risk of the formation of this type of abnormal clot (or thrombus). In addition, a portion of a blood clot (known as an embolus) formed in response to injury or surgery may sometimes break off and be removed in the  bloodstream.

The likelihood of this happening is increased by long periods of little or no activity. When an abnormal clot forms, there is a risk that it may become lodged in a blood vessel, thereby blocking the blood supply to a vital organ such as the brain or heart.

Anticoagulant drugs, such as this medicine, help to maintain normal blood flow in people who are at risk from clot formation. They can either prevent the formation of blood cloths in the veins or stabilize an existing clot so that it does not break away and become a circulation-stopping embolism.

All of the anticoagulant drugs reduce the activity of certain blood clotting factors, although the mode of action of each drug differs. However, this medicines do not dissolve the clots that have already formed; these clots are treated with thrombolytic drugs.
