Warfarin Sodium

CartPharmacy.Com

Warfarin Sodium is used to prevent harmful blood clots from forming or growing larger. This is given if you have:

    •    Pulmonary embolism (a blood clot in your lungs)

This occurs when a clump of material, most often a blood clot, gets wedged into an artery in your lungs. These blood clots most commonly come from the deep veins of your legs. Pulmonary embolism is a blockage in one of the pulmonary arteries in your lungs. In most cases, pulmonary embolism is caused by blood clots that travel to the lungs from deep veins in the legs or, rarely, from veins in other parts of the body.

    •    Deep vein thrombosis (a blood clot elsewhere in your body)

The blood clots of deep vein thrombosis can be caused by anything that prevents your blood from circulating or clotting normally. This occurs when a blood clot forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling but also can occur with no symptoms. This can also develop if you have certain medical conditions that affect how your blood clots. It can happen as well if you don’t move for a long time, such as after surgery or an accident, or when you’re confined to bed. Deep vein thrombosis can be very serious because blood clots in your veins can break loose, travel through your bloodstream and lodge in your lungs that will block blood flow.

    •    A blood clot in or near your heart that could trigger organ damage, heart attack, or stroke

    •    A mechanical artificial heart valve that is prone to forming blood clots

    •    A high risk of blood clots forming in the heart. It can be a complication of some heart rhythm abnormalities

Preventing harmful blood clots helps to reduce the risk of a heart attack or stroke.

How does Warfarin Sodium work?

The development of a clot in the body is a complex procedure that includes various substances. Warfarin Sodium lessens the ability of the body to form blood clots. It is by hindering the development of vitamin K-dependent clotting factors. Vitamin K is needed to make clotting factors and prevent bleeding. Therefore, by giving this medication, your body may stop harmful clots. This may also help you prevent clots from getting larger.

The blood clotting process is complicated. It begins when blood platelets clump together and produce chemicals that activate clotting factors in the blood. Clotting factors are proteins that are produced by the liver. Vitamin K is essential for their production. The activated clotting factors cause a protein called fibrinogen to be converted into another called fibrin. Fibrin binds the platelets together, forming a blood clot.
