Non-originator low molecular weight heparins: generics or biosimilars

First developed in the 1980s, low molecular weight heparins (LMWHs) are complex anticoagulants derived from porcine intestinal mucosa and are used in the treatment of deep vein thrombosis and pulmonary embolism. Heparin sodium’s anticoagulant activity is mainly governed by its ability to bind to the serine protease inhibitor antithrombin (AT). In this sense, heparin sodium functions as a cofactor for AT by modifying its conformation, thereby accelerating the inactivation of clotting factors.
