How Does Low Molecular Weight Heparin Work?

Low molecular weight heparin is an anticoagulant drug used for removing blood clots in the legs and other parts of the body. Low molecular weight heparin is injected subcutaneously or intravenously.

Antithrombin is a small protein molecule that inactivates several enzymes involved in blood clot formation. Low molecular weight heparin activates antithrombin, thus preventing blood clot formation.

Low molecular weight heparin is used to prevent blood clots and to treat venous thromboembolism (deep vein thrombosis and pulmonary embolism). Low molecular weight heparin is also used in the treatment of myocardial infarction.
