Enoxaparin is a low molecular weight heparin marketed under the trade names Lovenox, Xaparin and Clexane, among others. It is an anticoagulant used to prevent and treat deep vein thrombosis or pulmonary embolism, and is given as a subcutaneous injection (by a health care provider or the patient). Its use is evolving in acute coronary syndromes (ACS).

Enoxaparin is manufactured by Sanofi and is derived from the intestinal mucosa of pigs. Generic versions are available from Amphastar Pharmaceuticals and Sandoz.
