How does it work?

Enoxaparin is a medicine known as a low molecular weight heparin. It is an anti-clotting or anticoagulant medicine, and works by interfering with the body's natural blood clotting mechanism. Blood clotting involves a complex series of pathways. Enoxaparin inactivates a compound in this pathway called thrombin, which plays an important role in blood clot formation. Therefore, enoxaparin prevents the formation of blood clots (thrombosis) in the body. Blood clots within the body can be dangerous as they can travel in the blood vessels and potentially block off blood supply to the heart, lungs or brain. Enoxaparin is given by injection under the skin, and is used to prevent clots forming in the blood. This can occur in various conditions where the normal blood circulation is disturbed. Surgery, particularly abdominal surgery, produces a risk of thrombosis, as does a heart attack and poorly controlled angina (unstable angina). Clots can also occur when people are bed-ridden for long periods of time. Enoxaparin is given to prevent thrombosis in these groups of people. In addition, enoxaparin is used to prevent blood clotting when it is filtered through a kidney dialysis machine. Enoxaparin is also used to treat blood clots which have formed in the veins of the leg (deep vein thrombosis), as these may otherwise detach and travel in the circulation to the lungs causing a pulmonary embolism.
